Xcode 8 Code signing error

Question

I have Xcode 8 installed on OSX el Captain.

I have a stickers bundle which runs on simulator. However, when I build it on me errors as below:

Check dependencies Signing for "StickerPackExtension" requires a development team. Select a development team in the project editor. Code signing is required for product type 'App Extension' in SDK 'iOS 10.0'

Showing Recent Errors Only Signing for "StickerPackExtension" requires a development team. Select a development team in the project editor.

Code signing is required for product type 'App Extension' in SDK 'iOS 10.0'

I have tried creating the certificates again, clean build, restarting Xcode but the error is still there. I have also tried 'automatic manage signing' and changed the settings manually as well.

Please help!

Answer 1

The issue for me was selecting the Signing Profile Team for both Targets: The extension and the wrapper application.

It's not obvious, but if you open the drop-down to the left of General with the name of your app and select StickerPackExtension, you can then set the Team for the extension.
