Sometimes you want to grab all the directory and files you wrote into your app's document directory for testing/debugging. When running on the simulator, you can print the document directory and access it directly. How's how you can do it on an actual device:

1. Plug in your iOS device via USB
2. In Xcode, choose Window > Devices
3. Click on your iOS device under DEVICES
4. Under Installed Apps, click on your app
5. Click the gear button
6. Click Download Container

This will download the entire sandbox container, including temp files.

Happy debugging!
