Answer 1

Try this:

let bundleID = NSBundle.mainBundle().bundleIdentifier

Swift 3+:

let bundleID = Bundle.main.bundleIdentifier

Do you know why bundleIdentifier is an optional? In what cases can it be nil? – Nobody

Sometimes it isn't about in what cases it could be nil when it reaches the high level development, but about which cases it could be nil under the hood. – String

@Nobody when it is not the main bundle, or CFBundleIdentifier is missing – Floridafloridia

@Nobody It’s nil for unbundled applications’ main bundles and applications whose info.plist files don’t have an entry for the identifier. – Ierna

@Andreasdetestscensorship Boy I wrote that 7 years ago, wild how the time passes by. I've since run into both of those case (typo in the Info.plist key name, and unbundled executables). Makes sense! Thanks for sharing – Nobody

It's pretty much the same thing in Swift except the class and method names have been shortened:

let bundleIdentifier = Bundle.main.bundleIdentifier // return type is String?

Answer 3

If you are trying to get it programmatically , you can use below line of code :

Objective-C:

NSString *bundleIdentifier = [[NSBundle mainBundle] bundleIdentifier];

Swift 3.0:

let bundleIdentifier =  Bundle.main.bundleIdentifier

Updated for latest swift It will work for both iOS and Mac apps.
