I previously used the built-in template to add an iMessage extension target to my existing app and all is working fine. For development purposes I wanted to create a duplicate of the extension/container app pair, but with different bundle ID's. I duplicated the 2 Targets in XCode, and updated their bundle ID's and provisioning profiles. Everything is basically working, but for a few oddities:
1. If I Run the new extension, the debugger also launches and attaches to the old extension.
2. When I run the new extension, it does not automatically build and install the container app as previous pairing did
I searched through all the visible settings, and can't see where this behavior is determined. I manually editted the .xcscheme file and saw that the new extension was missing the RemoteRunnable section where BundleIdentifier = "com.apple.MobileSMS" was specified. I couldn't find that anywhere to set that in XCode UI, so I manually added to the xcsheme, but didn't fix the oddities. Anyone know how to fix this?
