I am making an attempt to write down a quite simple extension to show a sticker. None of Apple’s pattern code works on system or in simulator. I can not inform if it is a full regression on Apple’s half or one thing particular to my setup. The one error message that the console shows is:

Error creating the CFMessagePort wanted to speak with PPT.

I’ve used this pattern code: making a sticker app and have additionally tried the vanilla ‘Sticker Pack App’ at File > New > Undertaking > Sticker Pack App. In each instances, iMessages exhibits an icon of my app within the extension checklist, however no photographs are displayed. I’ve tried utilizing photographs of assorted sizes per the steering right here, however stickers nonetheless refuse to show.

Is a brand new entitlement/setting required by Apple that isn’t flipped on within the pattern code or Xcode template?

I am utilizing Xcode 15.1 and iOS 17.2
