Prevent to crash bc. missing access rights

Question

I have a folder, I like to be opened by NSWorkspace. But if access rights are missing, the entire app is crashing. How can I aviod this and show a message, that access rights were missing? I tried "try-catch", but this function does not throw errors!

NSWorkspace.shared.open(urlOutput)   // this could crash

Error message? Crash log? According to the documentation this method should return false if the file cannot be opened — Joakim Danielson, Apr 03 '23 at 07:18

You can use isReadableFile method in FileManager.

if FileManager.isReadableFile(atPath: urlOutput.path) {
     NSWorkspace.shared.open(urlOutput)
    
} else {
     //Show an Error Message
}

@Peter71 At best this is a workaround but doesn't resolve the issue with the crash. – Joakim Danielson Apr 03 '23 at 09:57
If I avoid calling the crashing function, that's the solution. – Peter71 Apr 05 '23 at 11:25
