Where should I be setting autolayout constraints when creating views programmatically

Question

I see different examples where constraints are set. Some set them in viewDidLoad / loadView (after the subview was added). Others set them in the m

Answer 1

You can set them in viewWillLayoutSubviews: too:

 override func viewWillLayoutSubviews() {

    if(!wasViewLoaded){
        wasViewLoaded = true

        //update constraint

        //also maybe add a subview            
    }
}
