NSOpenPanel/NSSavePanel crashes in Swift 3

Question

In Swift 3/Xcode8.1/10.12.2 I am trying to use a NSOpenPanel to get a text file with the following code, written by DenBeke

@IBAction func browseFile(sender: AnyObject) {

  let dialog = NSOpenPanel();

  dialog.title                   = "Choose a .txt file";
  dialog.allowedFileTypes        = ["txt"];

  if (dialog.runModal() == NSModalResponseOK)
  {
     let result = dialog.url // Pathname of the file

     if (result != nil) {
        let path = result!.path
        print("browseFile path: \(path)")
        //filename_field.stringValue = path
     }
  } else {
     // User clicked on "Cancel"
     return
  }
}

The code opens a open dialog as expected and I can choose a file. Clicking the open button crashes the app. In the console I get:

FI_TFloatingInputWindowController object 0x60800009c0c0 overreleased while already deallocating; break on objc_overrelease_during_dealloc_error to debug

When I run the code and open the dialog, in the console I get

[default] [ERROR] Failed getting container for URL: file:///Users/ruediheimlicher/Documents/LoggerdataDir/Messungen/, error: Error Domain=BRCloudDocsErrorDomain Code=12 "App library not found: 'com.apple.Documents'" UserInfo={NSDescription=App library not found: 'com.apple.Documents'}

but this does not affect the app.

There are more examples for NSOpen or NSSave dialogs on the net with slightly different code, but with everyone I get the same result: Crash, and the exact same error on the console.

Is there a mistake in my code attempts, or even an example that works with Swift3/sierra?

Give your app access to user selected files under <Your Project> -> <Your Target> -> Capabilities -> App Sandbox -> File Access -> User Selected File.

I have no such setting in my project. – heimi Nov 30 '17 at 20:12
@heimi I adjusted my answer to the latest Xcode version. – John Dec 01 '17 at 21:06

I now get logs with 'Faild to get owner UUID for url:' with URL's pointing to a file on a computer I was last logged in as an administrator 6 years before. – heimi Dec 05 '17 at 14:24
heimi did you ever resolve this? I am getting this too. Could it be coming a preference file somewhere? – adamteale Feb 14 '18 at 09:12

To remove this output you have to enable iCloud Drive in your Finder preferences.

Open finder
Open prefences
Select third tab (Sidebar)
Check iCloud Drive

Then rerun your application

iCloudPreferences are for a Code 2 error: `Code=2 "Logged out - iCloud Drive is not configured" UserInfo={NSDescription=Logged out - iCloud Drive is not configured}` but the above error is a Code 12 `App library not found` which iCloudPreferences doesn't resolve. – silicontrip Mar 13 '21 at 07:36
