When I package from XCode via Fabric Plugin a Beta in debug mode, I got an error :
Fabric Archive packaging Error -6
In Xcode I have check code signing manual (or auto same problem) for the app and the widget/extension with valid certificates and provisionning.
I also check that I have all certificates (public/private keys) and provisionning on my keychain.
If I build with fastlane last version 2.58.0, I got the same issue than direcly build from XCode.
Note that without any changes, one day it's work, an other that fails. This is strange.
Any help?
Even if you have the certificates and profiles on your keychain, you may need to refresh them. To do this in Xcode 9, follow the instructions here: https://stackoverflow.com/a/46686725/6543020
