All iOS apps must store an app version number in their Info.plist file, but there’s no build-in way to get that as a string you can use in your code.
Fortunately, we can write a small extension to UIApplication that reads the Info.plist file and returns a version number automatically. This might not exist for some reason, so we’re going to make a static variable that returns an optional string in case there was a problem reading it.
Here’s the code:
extension UIApplication {
static var appVersion: String? {
return Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as? String
}
}Available from iOS 8.0
