Transform a Image in Swift 3

Question

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're rotating over the y axis. You probably want to rotate over the z axis. — Lily Ballard, Sep 22 '17 at 22:14
Thanks very much Okan Yucel, the solution you linked me to worked perfectly! — imjonu, Sep 23 '17 at 01:58

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!
