I'm trying to check if the a user default exists, seen below:
func userAlreadyExist() -> Bool {
var userDefaults : NSUserDefaults = NSUserDefaults.standardUserDefaults()
if userDefaults.objectForKey(kUSERID) {
return true
}
return false
}
However, no mater what it will always return true even when the object doesn't exist yet? Is this the right way for checking existence ?
Astun has a great answer. See below for the Swift 3 version.
func isKeyPresentInUserDefaults(key: String) -> Bool {
return UserDefaults.standard.object(forKey: key) != nil
}
