Crash in WidgetExtensionContext.getDescriptors(completion:)

Hi,

I've been working on a Widget Extension which works great locally (when installed via Xcode) but it crashes when distributed via TestFlight. Most of the crashes occur at WidgetExtensionContext.getDescriptors(completion:)

Here's the crash log:

I've seen multiple reports about the 3rd party widgets not appearing for TestFlight builds in the PB3, but I am not sure if this is related.

What can I do to solve this? Thank you!

Ah, the widgets now show up. I archived the project using Xcode beta 2 using old placeholder API.

Yes, this is the same issue that is reported in multiple different threads. WidgetKit crashes when a widget is installed from
a TestFlight build that was compiled with Xcode 12 beta 3.

I am gonna try building it with Xcode 12 beta 2 to see if this is related to Xcode or iOS. Will post the results soon.

Hi,

I'm having the same issue, test it on Xcode Beta 5.

WidgetKit: closure #1 in WidgetExtensionContext.getDescriptors(completion:) + 208

On Organizer.

The new beta 5 needs to implement in the TimeLineProvider a new method called getSnapshot. Despite being implemented, the same thing happens.

Locally the widget shows in the widget gallery, but when upload to TestFlight, doesn't appear on the gallery.

Has anyone seen this recently? I get the same WidgetExtensionContext.getDescriptors(completion:) error using Xcode 12.0.1. Locally and TestFlight show no issues, but I am seeing the crashes via Organizer/Crashes in production.

Any help would be greatly appreciated.

I see crashes for this too, and in production not just TestFlight. If anyone ever finds a solution or how to debug further please share 🙏
