I get the following error when trying to run my WatchKit app:
Please try again later. This app has the ITSWatchOnlyContainer key set in its Info.plist, which identifies it as a shell app surrounding a Watch-only app; these are not installable.
I checked the Plists, there is no ITSWatchOnlyContainer entry.
Strangely enough the watch app starts if I check off: supports running without iOS app installation.
If you added a watch project into your iOS existing app. This might be the cause of the problem.
To fix this one:
Check for WKCompanionAppBundleIdentifier in Info.plist located in WatchKit App Folder. If it does not exist, add it and the value for this should be the bundle identifier of your ios app.
In Info.plist located in WatchKit Extension folder, replace App is only available as a standalone watchOS app to App can run independently of companion iPhone app. Clean build & run. This should work after. If not, try closing and reopening the Xcode.
