Transform a Image in Swift 3

So I have this simple problem where I need to rotate a CALayer 90 degrees. The problem is however, that it seems none of the methods I have found from research actually do anything. Below is the code I am using where imgLayer is a CALayer

var transform = CATransform3DIdentity
transform = CATransform3DRotate(transform, (CGFloat(Double.pi/2)), 0, 1, 0)
imgLayer.transform = transform

From what I have read this code should work but it does not seem to have any affect at all and I was wondering whether anyone had any suggestions as to why this is the case. Any help on the topic would be greatly appreciated, thank you.

Regards, Nick

You can first set your image in imageView and rotate get your image in imageView

Here: 

    let customImageView = UIImageView()
    customImageView.frame = CGRect.init(x: 0, y: 0, w: 250, h: 250)
    customImageView.image = UIImage(named: "yourImage")

    customImageView .transform = customImageView .transform.rotated(by: CGFloat.init(M_PI_2))
    var rotatedImage = UIImage()
    rotatedImage = customImageView.image!
