I know that there is already a solution to this question, but I found an alternative to this issue and maybe it could help someone.

I was having trouble with setting the frame of my sub view because certain values were referring to its position within the main view. So if you don't want to update your frame by changing the whole frame via CGRect, you can simply change a value of the frame and then update it.

// keep reference to you frames
var questionView = questionFrame.frame
var answerView = answerFrame.frame

// update the values of the copy        
questionView.size.height = CGFloat(screenSize.height * 0.70)
answerView.size.height = CGFloat(screenSize.height * 0.30)

// set the frames to the new frames
questionFrame.frame = questionView
answerFrame.frame = answerView
