Programmatically change the height and width of a UIImageView Xcode Swift

The accepted answer in Swift 3:

let screenSize: CGRect = UIScreen.main.boundsimage.frame = CGRect(x: 0, y: 0, width: 50, height: screenSize.height * 0.2)

ios xcode swift uiimageview

let screenSize: CGRect = UIScreen.mainScreen().boundsimage.frame = CGRectMake(0,0, screenSize.height * 0.2, 50)

ios xcode swift uiimageview

Using autoview

image.heightAnchor.constraint(equalToConstant: CGFloat(8)).isActive = true
