ios – CATransition sort fade appear damaged

When engaged on this query, I discover that perhaps fade of CATransitionType in CATransition not working or damaged. The remainder of CATransitionType: moveIn, push, reveal works accurately.

I am engaged on iPhone 13, iOS 16.0.

Code of the transition

extension CALayer {
    func makeFadeTransition() {
        let transition = CATransition()
        transition.timingFunction = CAMediaTimingFunction(identify: .easeInEaseOut)
        transition.period = 0.5
        transition.sort = .fade
        self.add(transition, forKey: nil)
    }
}

Utilization

self.customView.layer.makeFadeTransition()

I do know that we are able to change to utilizing UIView.animate mix with alpha to vary opacity as an alternative

UIView.animate(withDuration: 0.15, animations: {
    self.customView.alpha = 0.0
})

or utilizing CABasicAnimation

extension CALayer {
    func makeFadeTransition() {
        let transition = CABasicAnimation(keyPath: "opacity")
        transition.timingFunction = CAMediaTimingFunction(identify: .easeInEaseOut)
        transition.period = 0.5
        transition.fromValue = 1.0
        transition.toValue = 0.0
        self.add(transition, forKey: nil)
    }
}

However once more, is CATransitionType sort fade damaged or I am unsuitable at one thing.
Thanks in superior.
