I'm trying to use the NSSavePanel and added this line to my code.

    let test = NSSavePanel()

Everytime this code is called the this error appears. I'm not quite sure what is happening here because I'm only creating a new object. Any help appreciated. Thanks!

Your "File Access" permissions for the "User Selected File" type are probably still set the default "Read Only" value

  1. Navigate to the 'Capabilities' tab for your target

enter image description here

  1. Set the "User Selected File" permission to "Read/Write"

enter image description here

  1. Run your app (the bridge absent error should be gone)
