While trying to use the NSSavePanel, there is an error at run time. The Error is: ERROR: Unable to display save panel: your app has the User Selected File Read entitlement but it needs User Selected File Read/Write to display save panels. Please ensure that your app's target capabilities include the proper entitlements. The code is:         let targetPath = NSHomeDirectory()         let mySave = NSSavePanel()         mySave.title = "Save a File Here"         mySave.prompt = "Save Me"         mySave.directoryURL = URL(fileURLWithPath: targetPath.appending("/Desktop"))         mySave.canCreateDirectories = true         mySave.showsHiddenFiles = false         mySave.allowedFileTypes = ["adi"] Note: I did add code for using the NSSavePanel to ensure the program could write directly to a file. That code worked as expected. The the program can write to a file.
