I'm trying to collect health data in my Apple Watch application but when I call healthStore.requestAuthorization my app always crashes. I have set NSHealthShareUsageDescription and NSHealthUpdateUsageDescription in Info.plist as required but it still crashes. I started a new project and am just trying to request authorisation, there is no other functionality that could affect it. Any ideas why this is? Thanks for any help.
I was having the same issue using SwiftUI. But building a new project, using storyboards, revealed that the error was with my Info.plist strings. Apparently just a word or two is insuffcient.
Hopefully we'll get error messages passed through in SwiftUI soon.
Using longer strings solved my issue. I really hope this helps.
Cheers.
Thanks for the response. This still hasn't fixed the issue for me though. I'm using storyboards and my Info.plist strings are a length that should be suitable. No error is printed to the console so I have no reference as to what the problem could be.
I'm also experiencong the same issue - until Xcode 11.3, crash was happening without error message. With Xcode 11.4, the error displayed is:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'NSHealthUpdateUsageDescription must be set in the app's Info.plist in order to request write authorization for the following types: HKQuantityTypeIdentifierDietaryWater'
The string `NSHealthUpdateUsageDescription` is correctly set, along with `NSHealthShareUsageDescription`.

Turns out the permissions strings need to be set on the Info.plist that lives in the `WatchKit Extension` directory, not the `Watchkit App` one. When set there, the app correctly prompts for the Health permissions.
