I've written an app and set the two properties

'Supports opening documents in place' and 'Application supports iTunes file sharing'

to 'YES' in the Custom iOS Taget Properties.

My app is saving a .json file to the appropriate documents folder. When I start the fileimporter via

.fileImporter( isPresented: $showFileImporter, allowedContentTypes: supportedTypes, allowsMultipleSelection: false, ...

and supportedTypes -> let supportedTypes : [UTType] = [UTType.json]

All files are greyed out and I can't open them. What am I doing wrong!?

I would be very grateful for your support!

greets

René
