iOS Sounds and Ringtones

List of changes:

• Updated to iPhone X interface
• Adapted to Swift 4
• Uses iOS 11 large titles
• App now supports landscape mode and iPad

This is a small project demonstrating of how to locate and use system sound files. I hope this helps you.

What it Does

• Lists all of the pre-installed system sounds on an iOS device from the /System/Library/Audio/UISounds and /Library/Ringtones and their sub-folders.
• Allows users to:
• Click to play the sound listed.
• Swipe from left to right to bookmark sounds for quick reference.
• Reorder or delete bookmarked sounds.

Unfortunately, this app WILL NOT WORK in the iOS simulator. You must run it on an iOS device (iPhone, iPad, iPod Touch).

I created this app to solve a particular problem. Wanting to take advantage of the system sounds already in the phone for a project I had a hard time finding documentation of the files saved in iOS 8 devices. I'm fairly certain that this will work on iOS 7 devices, but I'm not sure. I cannot test in the simulator nor do I have any devices still running iOS 7 (sorry).

This is a utility app for devlopers really. Not for the general public. I tried to keep the code and formatting as spartan as possible in order to not make things difficult to view and absorb. It's the bare minimum with a fair amount of comments to help new programmers.

How it works

Frontend

• The app lists all of the user's bookmarked sounds (if any) as well as provides a link to browse all sounds in the /System/Library/Audio/UISounds and /Library/Ringtones folders or deeper.
• Click cells to play a sound.
• Swipe from right-to-left to bookmark a sound.
• Swipe bookmarked sounds to remove from bookmarks.
• Click "Edit" button to rearrange bookmarks and/or remove them.

Backend

• The app starts in the /System/Library/Audio/UISounds and /Library/Ringtones folders and looks for any sub-directories on that level and puts them all in an array.
• The app goes to each directory in that array a finds the sound files in each and saves them all in a [NSDictionary] array of dictionaries for programmatic access.
• Bookmarked files are saved to the NSUserDefaults on viewWillDisappear and loaded on viewWillAppear.

How to make the sounds play

The key piece is really

let fileURL: NSURL = NSURL(fileURLWithPath: "\{directory}\{filename}.{extension}")
do {
    appController.audioPlayer = try AVAudioPlayer(contentsOf: fileURL)
    appController.audioPlayer.play()
} catch {
    debugPrint("\(error)")
}

All of the work in the app comes down to those few lines.
