ios – XCode Share and Widget Extensions not working after including native SPM bundle


Introduction of downside

This not too long ago began occurring once I added an inner bundle with shared code throughout principal app and extensions. Once I load the simulator by both setting our principal app because the goal or as the person extensions, the extensions don’t present up on the simulator. Once I construct and run the share extension to images, our app’s choice doesn’t present as much as share regardless of being a possible picture share goal. Once I run the widget extension, the choice so as to add our app’s widget doesn’t present up. These have been working fantastic on my companion’s units earlier than I added the shared bundle. Now it does not work on any of our units

enter image description here

Embedded binary just isn’t signed with the identical certificates because the guardian app

There’s one other bug that I’ve not too long ago stumbled throughout once I added the shared bundle. That’s
Embedded binary just isn’t signed with the identical certificates because the guardian app. Confirm the embedded binary goal’s code signal settings match the guardian app’s.
The logs present that this error occurs when constructing the widget extension. This construct error goes away once I allow Copy solely when putting in

The option that I pressed to enable/disable the above bug

The extensions have been working simply fantastic earlier than the bundle was added.

I initially thought it was a signing downside, however then we triple checked and acquired a correct Apple Growth Crew with Certs but it nonetheless does not work. I’ve set the interior bundle as a static bundle. As a aspect word, the interior bundle just isn’t explicitly signed (which I do not know tips on how to do). Nonetheless it’s added as a static library within the Frameworks, Libraries, and Embedded Content material part of each principal app and extensions (lest the imports do not work)

Malicious Code via AI Code Editors

The crux of the assault hinges on the guidelines recordsdata which are utilized by AI brokers to information their conduct, serving to customers to outline greatest coding practices and undertaking structure.

Particularly, it entails embedding fastidiously crafted prompts inside seemingly benign rule recordsdata, inflicting the AI instrument to generate code containing safety vulnerabilities or backdoors. In different phrases, the poisoned guidelines nudge the AI into producing nefarious code.

This may be achieved by utilizing zero-width joiners, bidirectional textual content markers, and different invisible characters to hide malicious directions and exploiting the AI’s capacity to interpret pure language to generate weak code by way of semantic patterns that trick the mannequin into overriding moral and security constraints.

Cybersecurity

Following accountable disclosure in late February and March 2024, each Cursor and GiHub have said that customers are liable for reviewing and accepting strategies generated by the instruments.

“‘Guidelines File Backdoor’ represents a major threat by weaponizing the AI itself as an assault vector, successfully turning the developer’s most trusted assistant into an unwitting confederate, probably affecting hundreds of thousands of finish customers by means of compromised software program,” Karliner mentioned.

“As soon as a poisoned rule file is integrated right into a undertaking repository, it impacts all future code-generation classes by staff members. Moreover, the malicious directions usually survive undertaking forking, making a vector for provide chain assaults that may have an effect on downstream dependencies and finish customers.”
