ios – Sandbox Receipt Validation Fails with Error 21003 on Bodily Gadget (Firebase Cloud RUN Perform & App Retailer Join)


I am creating an iOS app that makes use of in-app purchases (IAP) configured by way of App Retailer Join. For receipt validation, I’m utilizing a Firebase Cloud Perform to ahead the receipt knowledge to Apple’s sandbox verification endpoint. My setup is as follows:

Testing on a bodily iOS gadget utilizing a sandbox check account.
I’m utilizing the IAP merchandise as outlined in App Retailer Join.
The consumer retrieves the receipt utilizing SKReceiptManager.retrieveReceiptData() (by way of my customized helper) and sends it—together with the product ID—to my Firebase Cloud Perform.
I’ve verified that my APPLE_SHARED_SECRET (handed within the payload beneath the “password” key) is ready by way of atmosphere variables.
Regardless of checking that the receipt isn’t empty and trimming any additional whitespace, I repeatedly obtain an error from Apple with standing code 21003 (“The receipt couldn’t be authenticated”).
Beneath are related code snippets from my implementation:

Advantages of Swift Programming Language for iOS App Improvement


It was for fairly a very long time that Apple working techniques for cell phones, tablets, and computer systems have been primarily developed with Goal-C.

The 12 months 2014 flipped the whole lot round with the presentation of Swift – a contemporary, quicker, and simpler-to-implement programming language. It’s been greater than 10 years because the Swift 1.0 launch, and now, iOS builders expect the Swift 6.0 launch to convey much more highly effective options.

Swift has proved to be a viable various to Goal-C for a lot of tasks, and now, many firms are constructing their iOS apps with Swift tech stack. On this article, we’ll dive into Swift’s particulars and discover out when to make use of this programming language and if present Goal-C remains to be related.

What Is Swift?

Swift is a programming language developed by Apple Inc. and used for constructing native apps that run on the Apple and Linux working techniques.

Whereas Linux is a stand-alone platform, Apple working techniques embody a complete line of options like iOS for cell phones, macOS for computer systems, iPadOS for tablets, watchOS for smartwatches, and tvOS for Apple TV. Due to this fact, there may be a variety of software program functions that may be developed with Swift.

The Swift language first appeared in 2014 in its place answer to Goal-C, which was omnipresent on all of Apple’s platforms. Since its introduction, Swift has rapidly gained recognition, and in 2015, it grew to become open supply. Many builders admit that this programming language is far less complicated to code and simpler to learn.

As we speak, Swift has reached the highest place within the worldwide charts of programming languages. For instance, the TIOBE Index for April 2025 has ranked Swift twenty sixth among the many prime 50 programming languages.

Whereas within the PYPL PopularitY of Programming Language Index, Swift charted at quantity 11, and the Stack Overflow Developer survey talked about Swift because the sixteenth most liked growth language.

Within the survey of 2019, software program developer Andrew Madsen examined the highest 110 apps within the App Retailer with a Python script for leveraging Swift of their supply code. The developer came upon that 42% of the highest 110 apps are developed with the Swift programming language to a higher or lesser extent.

The apps with the most important share of Swift-based code gave the impression to be Walmart for iOS, with 80% of Swift, Microsoft Outlook, and Postmates utilizing 67% of the language, Tinder has 47% of it, and Starbucks consists of 35%.

Definitely, a a lot bigger variety of world-known manufacturers construct their apps with Swift, and it’s anticipated to proceed rising in recognition within the close to future.

Advantages of Swift Programming Language for iOS App Improvement

Benefits of App Improvement with Swift

As with every language, Swift has its personal execs and cons for. Regardless of some shortcomings, many builders nonetheless choose implementing the Swift code extra for fast and efficient iOS growth. Let’s take a better take a look at the benefits of Swift.

Open-Supply Availability

Swift is an open-source growth language. This implies it’s accessible for everybody who desires to dive into iOS growth.

Swift builders can contribute to language growth, sharing their options regarding bug fixing, greatest items of code, and numerous language enchancment concepts. In simply a number of years after changing into an open-source answer, Swift acquired a powerful and supportive neighborhood and an intensive variety of third-party growth instruments.

Quick Improvement

To rapidly construct functions, Swift offers software program builders with LLVM instruments, a set of modular and reusable compilers, and toolchain applied sciences. These instruments compile meeting code into machine code, leading to quicker code processing.

Furthermore, in accordance to Apple Inc., Swift is 2.6 occasions quicker than Goal-C and as much as 8.4 occasions quicker than Python.

Easy to Learn, Straightforward to Keep

Swift makes use of easy and expressive syntax and grammar. It’s a lot simpler to learn and write than Goal-C.

Software program builders want to put in writing much less code to create the identical duties in Swift moderately than in Goal-C. This leads to quicker coding, fast error dealing with, and simple upkeep because of a fewer variety of errors within the code.

In addition to, Swift consists of an Computerized Reminiscence Counting (ARC) characteristic. It tracks and handles the reminiscence utilization within the developed apps, excluding the need to do it manually. This fashion, Swift automates the routine processes of reminiscence administration, assuaging and accelerating the event course of many occasions.

Security Options

Swift additionally helps builders rapidly outline and eradicate bugs earlier than code compilation. To forestall code from crashing, it initializes variables earlier than their use, checks arrays, and integers for overflow, and manages reminiscence with ARC mechanically.

Furthermore, Swift has enhancements in its nil pointer which prevents its objects from being nil by default. This leads to a cleaner and safer code that doesn’t result in any errors throughout its compilation.

Enhanced Staff Scalability

With Swift, challenge managers can simply scale their growth groups and add extra builders as wanted. It’s doable as a result of simplicity, brevity, and readability of the programming language.

The specialists in Java, Python, C#, and C++ can code in Swift to some extent because of its proximity to those languages and English and shallow studying curve.

Interoperability

It’s doable to combine Swift with the Goal-C and Cocoa framework. Software program builders can interchangeably use Goal-C in Swift and Swift in Goal-C. This interoperability is particularly helpful for big and long-lasting tasks the place software program builders can leverage the outdated and fashionable options of the 2 languages in a single challenge.

Common Updates

In 2024, Swift builders launched its 5.10.1 model and we will await one thing new quickly. Apple continuously invests in language growth, making Swift a stable possibility for many who construct iOS apps regularly.

This fashion, builders can use Swift to construct apps for numerous Apple merchandise. Above all, ranging from Swift 5.0, it features a secure utility binary interface (ABI) that enables Apple to supply sturdy help for the language throughout the Apple platforms.

Swift Disadvantages

As for the disadvantages, there will not be so lots of them. Nonetheless, they’re vital to contemplate with a view to create first rate iOS functions.

pros and cons of swift

Instability

Swift is a younger growth language that undergoes numerous modifications and experiments. Which means that it has few normal libraries and a few growth frameworks.

Although the Swift neighborhood is rising quick and has many specialists, it nonetheless might not all the time be doable to seek out all of the programming options rapidly compared to different programming languages.

Swift Model Compatibility Points

As Swift builders introduce many language modifications in its newer variations, it’s susceptible to model compatibility points. This fashion, if a developer decides to shift to a more recent model of Swift, they might discover some difficulties, together with the need to rewrite their app’s code.

To deal with this challenge, Swift builders have created a Swift Migration Software for XCode that makes code migration from model to model a lot simpler.

Previous OS Model Compatibility Points

As Swift is a brand new growth language, it doesn’t work with the outdated OS working techniques. It begins solely with iOS 7, macOS 10.9, and helps later variations. For legacy tasks, software program builders have to make use of a longstanding Goal-C.

Lack of C++ Assist

Final however not least, earlier than selecting Swift to your subsequent challenge, be certain that it doesn’t rely upon the C++ programming language, as Swift and C++ will not be interoperable.

How It All Began At SCAND

In June 2014, the SCAND cellular growth staff, along with different software program growth specialists, have been watching the annual Apple Worldwide Builders Convention (WWDC).

At that convention, Craig Federighi offered Swift for the primary time. Our staff was excited in regards to the new language, which generated heated discussions in regards to the future and views of iOS growth.

Though the primary model was fairly uncooked, we understood that Swift would have nice potential. Due to this fact, with the primary Swift documentation and tutorial launch, our iOS staff dug into its particulars and began studying this new programming language.

We started creating prototypes primarily based on Swift 1.0 and, with time, began discovering new growth practices, changing into increasingly more skilled within the language.

The SCAND specialists have been studying Swift and evaluating it to the event of then present Goal-C. This helped us make an in depth examine of the variations between the 2 growth languages, their very own execs and cons, and for what tasks it’s higher to make use of one language over one other.

Now, SCAND builders broadly use Swift for iPhone app growth. This programming language permits the constructing of highly effective and efficient apps for numerous industries, together with FinTech, m-commerce, healthcare, leisure, and others.

Furthermore, our staff has studied the most effective practices for utilizing Swift along with Goal-C to contribute probably the most to the app growth tasks.

swift development language

Why Goal-C Is Nonetheless Standard

Swift is rapidly conquering the OS growth subject, however does it imply that the time of Goal-C has handed? Though Swift is less complicated to study and, in comparison with Goal-C, has extra fashionable instruments and properties, Goal-C will stick with us for longer.

The very fact is Goal-C has a big codebase, and plenty of apps nonetheless have this language at their core. It’s hardly doable to rebuild all these options and libraries developed with Goal-C only for the sake of utilizing a brand new language.

Furthermore, this programming language has existed for greater than 20 years within the growth market and is way more secure than Swift.

Apple builders have discovered a option to unite the 2 languages. It’s to enhance compatibility between the 2. Due to this fact, Goal-C creators nonetheless replace this language to raised alter it to Swift.

There are a number of circumstances when Goal-C works higher than Swift for OS growth:

  • A big codebase written in Goal-C, e.g., in case your challenge has greater than 100,000 code traces written on this language, it’s not price switching to Swift;
  • For those who plan to construct a framework or SDK, then Goal-C is a more sensible choice as a result of lack of Swift ABI stability, which is able to end in poor communication between the weather within the equipment code;
  • In case your tasks are constructed with C or C++ third-party frameworks, as Swift isn’t appropriate with these programming languages.

Conclusion on Swift Programming Language

Swift is a younger, rapidly growing programming language constructed with efficiency in thoughts. Many software program builders choose this programming language because it’s a lot simpler to put in writing and skim, debug, and keep, and it provides fashionable growth instruments.

In the meantime, many companies are additionally beginning to rent cellular builders who work with Swift because it permits constructing highly effective and efficient iOS software program options a lot quicker and at an inexpensive price.

 

Mega Fashions Aren’t the Crux of the Compute Disaster

Mega Fashions Aren’t the Crux of the Compute Disaster


Each time a brand new AI mannequin drops—GPT updates, DeepSeek, Gemini—individuals gawk on the sheer measurement, the complexity, and more and more, the compute starvation of those mega-models. The belief is that these fashions are defining the resourcing wants of the AI revolution.

That assumption is improper.

Sure, massive fashions are compute-hungry. However the largest pressure on AI infrastructure isn’t coming from a handful of mega-models—it’s coming from the silent proliferation of AI fashions throughout industries, every fine-tuned for particular purposes, every consuming compute at an unprecedented scale.

Regardless of the potential winner-takes-all competitors growing among the many LLMs, the AI panorama at massive isn’t centralizing—it’s fragmenting. Each enterprise isn’t simply utilizing AI—they’re coaching, customizing, and deploying non-public fashions tailor-made to their wants. It is the latter scenario that can create an infrastructure demand curve that cloud suppliers, enterprises, and governments aren’t prepared for.

We’ve seen this sample earlier than. Cloud didn’t consolidate IT workloads; it created a sprawling hybrid ecosystem. First, it was server sprawl. Then VM sprawl. Now? AI sprawl. Every wave of computing led to proliferation, not simplification. AI is not any totally different.

AI Sprawl: Why the Way forward for AI Is a Million Fashions, Not One

Finance, logistics, cybersecurity, customer support, R&D—every has its personal AI mannequin optimized for its personal operate. Organizations aren’t coaching one AI mannequin to rule their total operation. They’re coaching hundreds. Meaning extra coaching cycles, extra compute, extra storage demand, and extra infrastructure sprawl.

This isn’t theoretical. Even in industries which can be historically cautious about tech adoption, AI funding is accelerating. A 2024 McKinsey report discovered that organizations now use AI in a mean of three enterprise capabilities, with manufacturing, provide chain, and product growth main the cost (McKinsey).

Healthcare is a first-rate instance. Navina, a startup that integrates AI into digital well being data to floor medical insights, simply raised $55 million in Collection C funding from Goldman Sachs (Enterprise Insider). Vitality is not any totally different—business leaders have launched the Open Energy AI Consortium to convey AI optimization to grid and plant operations (Axios).

The Compute Pressure No One Is Speaking About

AI is already breaking conventional infrastructure fashions. The belief that cloud can scale infinitely to help AI progress is lifeless improper. AI doesn’t scale like conventional workloads. The demand curve isn’t gradual—it’s exponential, and hyperscalers aren’t maintaining.

  • Energy Constraints: AI-specific information facilities are actually being constructed round energy availability, not simply community backbones.
  • Community Bottlenecks: Hybrid IT environments have gotten unmanageable with out automation, which AI workloads will solely exacerbate.
  • Financial Strain: AI workloads can eat thousands and thousands in a single month, creating monetary unpredictability.

Knowledge facilities already account for 1% of world electrical energy consumption. In Eire, they now eat 20% of the nationwide grid, a share anticipated to rise considerably by 2030 (IEA).

Add to that the looming strain on GPUs. Bain & Firm lately warned that AI progress is setting the stage for a semiconductor scarcity, pushed by explosive demand for information center-grade chips (Bain).

In the meantime, AI’s sustainability downside grows. A 2024 evaluation in Sustainable Cities and Society warns that widespread adoption of AI in healthcare may considerably improve the sector’s vitality consumption and carbon emissions, except offset by focused efficiencies (ScienceDirect).

AI Sprawl Is Greater Than the Market—It’s a Matter of State Energy

When you assume AI sprawl is a company downside, assume once more. Essentially the most vital driver of AI fragmentation isn’t the non-public sector—it’s governments and navy protection companies, deploying AI at a scale that no hyperscaler or enterprise can match.

The U.S. authorities alone has deployed AI in over 700 purposes throughout 27 companies, masking intelligence evaluation, logistics, and extra (FedTech Journal).

Canada is investing as much as $700 million to develop home AI compute capability, launching a nationwide problem to bolster sovereign information heart infrastructure (Innovation, Science and Financial Growth Canada).

And there are rising requires an “Apollo program” for AI infrastructure—highlighting AI’s elevation from business benefit to nationwide crucial (MIT Know-how Overview).

Navy AI won’t be environment friendly, coordinated, or optimized for value—will probably be pushed by nationwide safety mandates, geopolitical urgency, and the necessity for closed, sovereign AI methods. Even when enterprises rein in AI sprawl, who’s going to inform governments to decelerate?

As a result of when nationwide safety is on the road, nobody’s stopping to ask whether or not the facility grid can deal with it.

AI Outperforms Physicians in Actual-World Pressing Care Choices, Research Finds – NanoApps Medical – Official web site


The research, carried out on the digital pressing care clinic Cedars-Sinai Join in LA, in contrast suggestions given in about 500 visits of grownup sufferers with comparatively frequent signs – respiratory, urinary, eye, vaginal and dental.

A brand new research led by Prof. Dan Zeltzer, a digital well being professional from the Berglas College of Economics at Tel Aviv College, in contrast the standard of diagnostic and therapy suggestions made by synthetic intelligence (AI) and physicians at Cedars-Sinai Join, a digital pressing care clinic in Los Angeles, operated in collaboration with Israeli startup Okay Well being. The paper was revealed in Annals of Inner Drugs and introduced on the annual convention of the American School of Physicians (ACP). This work was supported with funding by Okay Well being.

Prof. Zeltzer explains: “Cedars-Sinai operates a digital pressing care clinic providing telemedical consultations with physicians specializing in household and emergency care. Lately, an AI system was built-in into the clinic algorithm primarily based on machine studying that conducts preliminary consumption via a devoted chat, incorporates information from the affected person’s medical document, and gives the attending doctor with detailed diagnostic and therapy recommendations firstly of the go to -including prescriptions, exams, and referrals. After interacting with the algorithm, sufferers proceed to a video go to with a doctor who finally determines the analysis and therapy. To make sure dependable AI suggestions, the algorithm-trained on medical data from thousands and thousands of instances, solely affords recommendations when its confidence degree is excessive, giving no suggestion in about one out of 5 instances. On this research, we in contrast the standard of the AI system’s suggestions with the physicians’ precise choices within the clinic.”

The researchers examined a pattern of 461 on-line clinic visits over one month through the summer season of 2024. The research centered on grownup sufferers with comparatively frequent symptoms-respiratory, urinary, eye, vaginal and dental. In all visits reviewed, the algorithm initially assessed sufferers, supplied suggestions, after which handled them by a doctor in a video session. Afterwards, all suggestions from each the algorithm and the physicians have been evaluated by a panel of 4 docs with no less than ten years of scientific expertise, who rated every suggestion on a four-point scale: optimum, affordable, insufficient, or probably dangerous. The evaluators assessed the suggestions primarily based on the sufferers’ medical histories, the data collected through the go to, and transcripts of the video consultations.

The compiled scores led to attention-grabbing conclusions: AI suggestions have been rated as optimum in 77% of instances, in comparison with solely 67% of the physicians’ choices; on the different finish of the size, AI suggestions have been rated as probably dangerous in a smaller portion of instances than physicians’ choices (2.8% of AI suggestions versus 4.6% of physicians’ choices). In 68% of the instances, the AI and the doctor acquired the identical rating; in 21% of instances, the algorithm scored larger than the doctor; and in 11% of instances, the doctor’s choice was thought-about higher.

The reasons supplied by the evaluators for the variations in scores spotlight a number of benefits of the AI system over human physicians: First, the AI extra strictly adheres to medical affiliation guidelines-for instance, not prescribing antibiotics for a viral an infection; second, AI extra comprehensively identifies related info within the medical record-such as recurrent instances of an identical an infection that will affect the suitable course of therapy; and third, AI extra exactly identifies signs that might point out a extra severe situation, akin to eye ache reported by a contact lens wearer, which may sign an an infection. However, physicians are extra versatile than the algorithm and have a bonus in assessing the affected person’s actual situation. For instance, suppose a COVID-19 affected person stories shortness of breath. A health care provider might acknowledge it as a comparatively gentle respiratory congestion in that case. In distinction, primarily based solely on the affected person’s solutions, the AI may unnecessarily refer them to the emergency room.

Prof. Zeltzer concludes: “On this research, we discovered that AI, primarily based on a focused consumption course of, can present diagnostic and therapy suggestions which can be, in lots of instances, extra correct than these made by physicians. One limitation of the research is that we have no idea which physicians reviewed the AI’s suggestions within the accessible chart, or to what extent they relied on these suggestions. Thus, the research solely measured the accuracy of the algorithm’s suggestions and never their influence on the physicians. The research’s uniqueness lies in the truth that it examined the algorithm in a real-world setting with precise instances, whereas most research concentrate on examples from certification exams or textbooks. The comparatively frequent circumstances included in our research characterize about two-thirds of the clinic’s case quantity. Thus, the findings could be significant for assessing AI’s readiness to function a decision-support instrument in medical apply. We will envision a close to future by which algorithms help in an rising portion of medical choices, bringing sure information to the physician’s consideration, and facilitating sooner choices with fewer human errors. After all, many questions nonetheless stay about the easiest way to implement AI within the diagnostic and therapy course of, in addition to the optimum integration between human experience and synthetic intelligence in medication.”
