NSManagedObjectContext does not work in Swift

Question

@IBAction func btnSave(sender: AnyObject) {

    let appDel: AppDelegate = UIApplication.sharedApplication().delegate as AppDelegate
    let context: NSManagedObjectContext = appDel.managedObjectContext    
}

This does not work since it says it is not unwrapped.

Answer 1

Because managedObjectContext in application delegate is optional you should unwrap it with an exclamation mark change your code to this:

let context: NSManagedObjectContext = appDel.managedObjectContext!
