swift presentViewController programmatically finds nil in destinationVC VDL

Question

Trying to solidify my knowledge by understanding lines of code at a basic level.

I\'ve tweaked my app to use ViewController(VC)2 as initial VC instead of VC1.

Answer 1

So when instantiating a VC (storyboard-created), first we need to route our call through the UIStoryboard by name

let storyboard = UIStoryboard(name: "Main", bundle: nil)  

then instantiate a VC using the Storyboard ID of our storyboard setup VC

let vc = storyboard.instantiateViewControllerWithIdentifier("VC1") as VC1    //VC1 refers to destinationVC source file and "VC1" refers to destinationVC Storyboard ID

Then we can present VC using

self.presentViewController(vc, animated: true, completion: nil)

This will import all of destinationVC's objects with their IBOutlet references.
