Apple has shared a new support video on its YouTube channel, explaining how you can create a ringtone from an audio file, a song from your Apple Music library, or a song that you made.

To begin, you need to download the free GarageBand app on your iPhone. Once done, follow the steps below:
- On the Home screen, touch and hold the GarageBand app icon until the menu appears, then tap Create New Audio Recording.
- When GarageBand opens, tap the Tracks button at the top of the screen.
- Tap the instrument icon on the left to select the track, then tap the Loops Browser button at the top of the screen.
- Choose the track you want to use for a ringtone:
- To use an audio file stored on your device or in iCloud, tap Files, then tap “Browse items from the Files app.”
- To use a song from your Apple Music library, tap Music to find the file. The song must be downloaded to your iPhone. If the file is dimmed, it’s protected or isn’t downloaded to your iPhone. If the file is protected, you can’t use it for a ringtone.
- Touch and hold the file, then drag the file all the way to the left in the Tracks view.
- You can also use a particular section of the song for your ringtone (ringtones can be up to 30 seconds long).

#2 of the instructions already lost me. There is no tracks button at the top, just a bunch of icons
