iMsg extension for existing iOS app

Question

I'm trying to attach iMsg extension to an existing iOS app. After running an extension from xCode, I'm getting an error saying:

Could not locate installed application

Install claimed to have succeeded, but application could not be found on device. bundleId = 'extension bundle id'

Extension appears in iMsg apps section, but I can't attach it for debug.

Answer 1

I changed 'Executable' in my scheme from actual extension to 'Ask on lunch' and issue disappeared
