healthStore.requestAuthorization() crashes Apple watch application

Question

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.

Is there any crash log in console? – Larme Feb 05 '20 at 18:32 — Larme, Feb 05 '20 at 18:32
No, nothing. It crashes silently – Peter C Feb 05 '20 at 18:35 — Peter C, Feb 05 '20 at 18:35

I found what the issue was. There are two Info.plist files that need NSHealthShareUsageDescription and NSHealthUpdateUsageDescription. One in the project file and one in the watch extension file. I had only done one of these. The strings for these also need to be a reasonable length and cannot be just a couple of words.
