IOS Swift: Pass data to another controller

Question

I am trying to pass data from one view controller to another.... I have a collection view in the first view controller which is populated dynamically with an array and want it so that when an item is clicked... it opens up the second view controller (which I've done) but sends along data (in this case an array)

Ive looked into core data, but after trying to implement it thought it might be a bit "overkill" for such a basic function? (or am i wrong?)

Anyone have any ideas?

Thanks, Dave

Assuming you are using segues then prepareForSegue is the best way to do this. You override this in your initial view controller and are passed in a UIStoryboardSegue which has a segue.destinationViewController which you can use to set any data on that controller — Andrew

Thanks for the replies guys! I am using: var itemViewController = mainStoryboard.instantiateViewControllerWithIdentifier("projectViewController") as UIViewController self.presentViewController(itemViewController, animated: true, completion: nil) is there anyway I can pass data similar to the segues? Hi @jeffamaphone, how would I set a property on the target controller from my initial view controller? Thanks, Dave — David

Ok so i just tried something.... I set a variable in my app delegate file and then in my other controllers accessed it like this: let appDelegate:AppDelegate = (UIApplication.sharedApplication().delegate as AppDelegate); let context:NSManagedObjectContext = appDelegate.managedObjectContext!; println(appDelegate.test) it works...but is it ok to use the app delegate like this? Thanks — David

Have you tried using prepareForSegue:

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
        // pass data to next view
}

Or NSUserDefaults:

NSUserDefaults.standardUserDefaults().setObject(VALUE, forKey:YOUR_KEY)
NSUserDefaults.standardUserDefaults().synchronize()
