Swift instantiateViewController without storyboard ?programming

Question

Is there any way instantiateViewController without using storyboard ? I did not use storyboard.

Just create an instance of the view controller like you would any other class. What's your actual issue? — rmaddy, Apr 22 '17 at 15:40

Yes you can init you're controller with nib name:

let main = UIViewController(nibName: "Second", bundle: nil)

Also you can call constructor without parameters like:

let main = UIViewController()

thank you! let main = UIViewController() it worked I will accept your answer as correct – Kristoff Apr 22 '17 at 15:49
@Kristoff the first line is using from storyboard...basically wherever you see nibName it means *from* storyboard...The 2nd line is purely instantiating a viewController programatically...though you would also have feed the related properties of it ie buttons, labels,views,etc... – mfaani Apr 22 '17 at 15:58
@Honey first approach could be used with nibs also. – Oleg Gordiichuk Apr 22 '17 at 15:59

@Honey No, the first one is not using a storyboard. It's using a nib. You can have standalone nibs without ever using a storyboard. Nibs have been around much longer than storyboards. – rmaddy Apr 22 '17 at 16:31
@rmaddy ohh ok. Thanks for the correction. But don't you have to create that nib from storyboard? Or your saying you can create nibs programmatically? – mfaani Apr 22 '17 at 16:38

@Honey No, nibs are created in Interface Builder, without using a storyboard. Or when you create a new view controller class, Xcode gives you the option of also creating a nib. – rmaddy Apr 22 '17 at 16:42
@rmaddy Thanks...after 3000reps you expect to learn more complex stuff rather not knowing the diff between interface builder and storyboard #facepalm! – mfaani Apr 22 '17 at 16:46
