Watch embedded binary ' s bundle identifier is not prefixed with the parent app ' bundle identifier.

Error reason: The bundle ID of IPhone app, watch app and watch extension does not conform to Apple's naming convention. Its naming conventions must follow a fixed format.

The solution is as follows:

The following three items (project name my) are under the Targets of the project: My, my WatchKit app, my WatchKit extention

General-> Identity under the Bundle identifier are fixed written, do not casually change.

For example:

com.xxx.my

Com.xxx.my.watchkitapp

Com.xxx.my.watchkitapp.watchkitextension
