have the same issue. when compiling with xcode 15 widgets work on ios 15 (my minimum target). when compiling with xcode 16 b6, my widgets arent listed both on ios 15 devices and simulators.

have the exact same problem. anything lower than ios 17.2 will produce this error

Some of my users are reporting this too. And since the app is a widget design tool/editor that's a pretty big issue for me, since it renders the complete app useless to those users.

Just got the same error. My app is targeted to iOS14 since it relies on WidgetKit.

Can confirm, Apple fixed something and it works now as it should.

This is still not solved.
