I have an iPhone app with watch app and extension. I'm getting the following error when building: Embedded binary's bundle identifier is not prefixed with the parent app's bundle identifier.

I've followed the instructions as set out here: https://developer.apple.com/library/ios/technotes/tn2410/_index.html

The iPhone app bundle ID is 'com.myname.appname'

The watch app bundle ID is 'com.myname.appname.watchkitapp' (the 'parent' app bundle ID mentioned in the error)

The watch extension bundle ID is 'com.myname.appname.watchkitextension' (the embedded bundle ID mentioned in the error)

I've set the NSExtensionPointIdentifier to com.apple.watchkit

I've created three separate app IDs and three separate provisioning profiles.

Any help is appreciated.

I've solved the issue.

For those interested the extension bundle IDs should be as follows:

iPhone app bundle ID: com.myname.myapp

Watch app bundle ID: com.myname.myapp.watchkitapp

Watch extension bundle ID: com.myname.myapp.watchkitapp.watchkitextension

Cheers

After much trial and error, I landed on this. The prior replies helped but I needed a slight modification:

iPhone app bundle ID: com.myname.myapp
Watch app bundle ID: com.myname.myapp.watchkitapp
Watch extension bundle ID: com.myname.myapp.watchkitextension

In WatchOS Info.plist

<key>WKCompanionAppBundleIdentifier</key>
<string>com.myname.myapp</string>

In watcOS Extension Info.plist

<key>NSExtension</key>
	<dict>
		<key>NSExtensionAttributes</key>
		<dict>
			<key>WKAppBundleIdentifier</key>
			<string>com.myname.myapp.watchkitapp</string>
            ...
		</dict>
