Description Stuart Fischer 2016-10-27 16:05:33 UTC
This issue looks very similar to Bug #28078.

We have made a universal (supporting iPhone/iPod/iPad) app with a watchkit extension and watchkit app.

We found recently after upgrading Xamarin Studio (version 6.1.1 (build 15)) and Xamarin.iOS ( to latest release version, that our (jenkings command-line msbuild) release builds would no longer deploy successfully to iPads.

From investigation, we found with the new Xamarin Studio and Xamarin.iOS, that the Info.plist (post-modification by the normal Xamarin/iOS build process) for the watchkit app extension was missing the UIRequiredDeviceCapabilities key with watch-companion entry:


If we add the above manually to Info.plist (ie: commit this change to source control) for the watchkit app extension, the built app deploys to iPads successfully. Adding the dictionary entry to the .plist manually is the workaround from bug #28078, and it works again now).

I guess older versions of Xamarin Studio / Xamarin.iOS probably automatically added the UIRequiredDeviceCapabilities entry to the watchkit extension's Info.plist, but that functionality seems missing/broken now.

Without the workaround, the error we get at the console when we try to deploy the app to iPad is the same as that listed in the older bug:

"This app contains an app extension that specifies an extension point identifer that is not supported on this version of iOS for the value of the NSExtensionPointIdentifier key in its Info.plist"

Hi, so this bug is a duplicate of #44257.

I've created a pull request against our cycle8 branch so this fix makes it to our stable Xamarin.iOS as soon as possible.
