Resize image to iOS device background -


i rescale image fit width of ios screen. following code used.

@iboutlet var bgimageview: uiimageview  override func viewdidload() {     super.viewdidload()     bgimageview.contentmode = uiviewcontentmode.scaleaspectfit;     bgimageview.frame.size.width = uiscreen.mainscreen().bounds.width; }

this solution seems causing thread problems. what's wrong here?

you can set image view constrains follows - width should equal super view width, centerx , centery same super's. , height not equal constraint, lessthanorequal super's height.

and yes, useless set frame manually while using auto layout constraints
