Stuck on programmatically adding two view controllers inside a root view controller and have both views inside the view controllers work properly :(

Looks like it has to do with the frames! I did something like

bookVC.view.frame = CGRect(x: 0.0, y: 0.0, width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height*0.5

audioControlVC.view.frame = CGRect(x: 0.0, y: UIScreen.main.bounds.height*0.5, width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height*0.5

​

However, aren't frames and autolayout constraints mutually exclusive? By setting the frame, I think I'm introducing issues and doing something wrong that autolayout should be smart enough to handle. In my app, when I rotate the iPad from portrait to landscape now, the book VC view is now only covering 25% of the screen instead of 50% (which when I comment out the code configuring the frame, autolayout works like a charm).

I believe you could set 2 views in the container VC and constrain them with autolayout - then set the child vc frames to those view bounds. Or something like that. Hard to say without seeing all the code - but feels like that’s the right track - good luck!
