When you’re utterly new to Swift and iOS improvement (or want a brush-up), that is the sequence for you.
The UIKit Apprentice is a sequence of epic-length tutorials for newbies the place you’ll learn to construct 4 full apps from scratch.
Every new app will likely be a…
extra
This part tells you a couple of issues it’s good to know earlier than you get began, akin to what you’ll want for {hardware} and software program, the place to search out the challenge information for this guide and extra.
This part introduces you to the primary of the 4 apps you’ll construct over the course of this guide — Bull’s Eye.
As you progress by means of constructing the Bull’s Eye app, the part will train you suppose like a programmer and plan your programming duties. As well as, you’ll additionally learn to use Xcode, Interface Builder, and even the fundamentals of coding for iOS.
Whereas a few of the ideas on this part may appear a bit primary, please don’t skip this part in case you are new to iOS improvement – you’ll study some fundamentals which act because the constructing blocks for what you study later.
Welcome to The UIKit Apprentice! On this guide, you are about to deep dive into the newest and biggest Swift and iOS greatest practices. You’ll construct 4 iOS initiatives utilizing Swift and UIKit. Good luck!
On this chapter, you’ll begin constructing the preliminary display for the Bull’s Eye sport.
Congratulations, you could have a UIButton on the display! It is time to begin including the UISlider which will likely be basic to the sport.
On this chapter you’ll cope with random numbers, beginning a brand new spherical of the sport, and calculating the factors scored.
It is time to calculate and show the rating and the variety of rounds performed on this chapter.
Add some polish to the sport in order that it truly appears like a sport. Additionally, enable the person to re-start the sport in order that two folks can play the sport.
Let’s spruce up the sport UI with some fancy art work and make your sport stand out from the pack. Additionally, let’s add an About display with details about the sport.
Phew! You’ve got efficiently created Bull’s Eye. Within the remaining chapter of this part you’ll find out about supporting completely different gadget sizes and add some lovely animations.
This part builds upon what you learnt within the earlier part by introducing you to your second app. Checklists takes you from a single-screen app to a multi-screen app the place you study the ideas of navigation movement, displaying knowledge lists, and the concept of modeling and persisting your knowledge.
If you wish to construct any kind of list-based iOS app, this part is an effective start line for studying the fundamentals. In fact, even for those who aren’t constructing a list-based app, this part has some primary ideas akin to dealing with the navigation movement from one display to a different (and again once more) that might be very helpful to an apprentice iOS developer.
Add a desk view to point out a listing of to-do objects and within the course of find out about code navigation controllers and desk views for iOS.
On this chapter, we’ll arrange an information mannequin to characterize our guidelines objects after which use the information mannequin to show our to-do objects.
All about navigation controllers — add them, configure them, and use them. Additionally learn the way add a brand new display to your to-do app and add the flexibility to delete to-do objects.
Create the Add Merchandise display to your app and within the course of, learn to create customized desk view cells, get person enter, and add polish to knowledge entry screens.
You may find out about delegates and protocols, and use them to finish the add objects performance to your Checklists app.
Now that you may add objects, learn to edit added objects. Additionally, refactor your code to optimize it.
Checklists works nice however we won’t persist our knowledge — our to-do objects are reset every time the app is re-launched. Let’s learn to persist our knowledge between app periods.
From one listing to many – Checklists manages a single listing of things in the mean time. That is not very helpful. Let’s add the flexibility to have a number of lists of things.
Let’s enhance our knowledge mannequin in order that we are able to have completely different to-do objects for every guidelines. We’ll additionally implement a brand new saving technique within the course of.
Learn to save utility settings and different helpful info between app periods. Additionally, guard towards potential crashes and to enhance the first-run expertise of the app in order that your app appears extra polished and user-friendly.
With the fundamental performance to your Checklists app completed, it is time to add some polish and performance that makes your app stand out from the herd.
Learn to add native notifications to Checklists with the intention to be notified when a to-do merchandise is due and handle notifications by means of the lifecycle of a to-do merchandise.
With this third part and the MyLocations app, you get into Swift programming in earnest.
Certain, you’ve already coded apps within the earlier two sections, however this part begins off with a very good evaluate of all of the Swift coding ideas you’ve discovered to this point and provides to it by introducing some new ideas too.
Along with that, you find out about utilizing GPS coordinates, displaying knowledge on maps, and utilizing the iOS picture picker to take images utilizing your digital camera or to select present photos out of your photograph album. There’s a number of priceless normal info on Swift improvement in addition to particular details about constructing location-aware apps.
This part additionally introduces you to constructing apps for Darkish mode – a topic that you simply’ll do a deep-dive into within the subsequent part.
You’ve got made nice progress! You have learnt the fundamentals of Swift programming and created two functions from scratch. Now let’s add some extra Swift principle to strengthen the foundations we have constructed whereas creting these two apps.
That is the primary chapter on this part which teaches you create a “location album” app. Take the primary steps for creating this new app by studying use the Core Location framework to get your location and to show it.
You have been capable of entry location knowledge and show it within the final chapter. On this chapter, you’ll enhance upon that code by dealing with GPS errors and enhancing the GPS accuracy. You may additionally arrange the app to deal with completely different display sizes.
Time for some extra principle! You may study all about objects, lessons, inheritance, and some different object oriented ideas from Swift that it’s good to be conversant in.
Time to get again to coding once more. You may learn to construct the Tag Location display and arrange one other knowledge entry display for an iOS app.
The MyLocations app performance is slowly taking form now. So it is time to polish issues up a bit by enhancing the person expertise and including some UI thrives.
Study all about save your areas on the gadget utilizing Core Knowledge, the thing persistence framework for iOS.
Let’s present the information that you simply’re now capable of save through Core Knowledge as a listing of areas. Study TableView sections, NSFetchedResults and deleting tagged areas.
Let’s get visible! Present your tagged location on a map view utilizing MapKit with the intention to see the place on this planet every location is.
Learn to use the built-in picture picker in iOS so as to add photos from both the digital camera or the photograph album to your tagged areas.
It is time to give MyLocations an entire visible makeover! You may change the styling for the app, add buttons for motion objects, add sounds, icons, and launch photos.
The ultimate part of the guide covers constructing an app which helps each Gentle and Darkish appearances from scratch through the StoreSearch app. StoreSearch reveals you have separate customized belongings and colours for every sort of iOS look.
However that’s not all! The app additionally reveals you do customized screens each for particular orientations (panorama vs. portrait) in addition to for particular platforms (iPhone vs. iPad). This part covers networking, working with distant API endpoints to fetch knowledge wanted by your app, and parse the fetched knowledge, work with Stack Views, and add iPad assist to your app.
If that wasn’t sufficient, this part additionally takes you thru the total utility life cycle – from creating the code, testing it, and all the best way to submitting to Apple. So don’t skip this part considering that you understand all about iOS improvement after the previous couple of sections!
Most iOS job listings say that it’s good to have labored with a REST API. Properly, this chapter begins you on a brand new app which can train you all about fetch knowledge from a distant server and get you on the trail to REST API mastery.
Learn to show your knowledge in a desk view utilizing customized desk cells. Additionally change the appearnace of the app and do a little bit of debugging.
