Prevent to crash bc. missing access rights

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
Solution

  • You can use isReadableFile method in FileManager.

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