Unfortunately, Uninstalling app, emptying trash then restarting did not solve the error. I still keep getting same error NOTE: When I change bundle identifier in Xcode to something else, I was able to add new domain but after I changed it back to previous identifier, I start to get same error Any suggestion about this?

Bumping the value of the CFBundleVersion entry in the Info.plist file (of both app and extension) fix the problem. I was able to add new domain. But after I changed it back to previous version, I start to get same error
