iPhone WatchKit Companion App Display Name

Question

If you open the Apple Watch application on your >= iOS 8.2 iPhone, you get a list of applications, featuring watch apps.

Where can I define the name, displayed next to the watch app's icon?

Answer 1

As per this Apple note:

CFBundleDisplayName (Bundle display name) within the Info.plist of the iPhone App corresponds to the name as viewed on the iPhone, while the value in CFBundleName (Bundle name) is the one used within the WatchKitSettings app:

CFBundleDisplayName (Bundle display name) in the Info.plist file for the WatchKit App is tied to the name that is displayed on the Apple Watch itself:

Answer 2

Its weird and may change in the future, but it's the "Bundle Name" (CFBundleName) of the parent iOs Application which is used in the iOs Apple Watch Companion Application as the Watch Application Name.

But in the Watch Application, it's the "Bundle Display Name" (CFBundleDisplayName) of the Watch application which is used (same as on iPhone).

In the 2 cases, you can localized them using InfoPlist.strings with :

"CFBundleDisplayName" = "Whosnext";
"CFBundleName" = "Whosnext";

Moreover, if name of Watch and iPhone application differs, your application will be rejected.
