You have to be careful when changing the bundle identifiers, and here's how they should be set (you need to change each identifier in the Info.plist for the iPhone app, for the Watchkit Extension and for the Watchkit App):

iPhone Application Info.plist:

Set any bundle identifier as you like (the "Bundle identifier" property).

Example:

Bundle identifier: com.fruitcompany.orange

WatchKit App Info.plist

The bundle identifier here must be prefixed with the identifier of the iPhone application, like this(example):

Bundle identifier: com.fruitcompany.orange.watchkit

You also need to change the WKCompanionAppBundleIdentifier which must match with the iPhone application bundle identifier, like this:

WKCompanionAppBundleIdentifier: com.fruitcompany.orange

WatchKit Extension Info.plist:

The bundle identifier here must be prefixed with the identifier of the iPhone application, like this(example):

Bundle identifier: com.fruitcompany.orange.watchkit.extension

You also need to set the WKAppBundleIdentifier under the NSExtension attribute.

The WKAppBundleIdentifier identifier must match with the WatchKit app bundle identifier like this:

WKAppBundleIdentifier: com.fruitcompany.orange.watchkit

Don't forget to check that your Bundle ID in project target is the same as in Info.plist!
