How to Animate a UIImage out of the Screen in Swift - animation

Question

i have searched around the web but nothing could answer my question.
I am trying to animate an UIImageview out of the Screen, set the alpha of it to 0, reset its position and reset the alpha to 1 again.
I can't seem to get the right position where to animate the Image to.
I have set up a gesturerecognizer to drag the image around and when the center of the image is above a certain point, i want to animate it out of screen.
This is the Regocnizercode :
#objc func imageDragged(gestureRecognizer: UIPanGestureRecognizer){
//Current Point where the label is dragged
let draggedLabelPoint = gestureRecognizer.translation(in: view)
//Updating the center of the label : viewcenter +/- currentpoint
matchImageView.center = CGPoint(x: view.bounds.width/2 + draggedLabelPoint.x, y: view.bounds.height/2 + draggedLabelPoint.y)
let xFromCenter = view.bounds.width/2 - matchImageView.center.x
var rotation = CGAffineTransform(rotationAngle: xFromCenter / -500)
let scale = min(100/abs(xFromCenter),1)
var scaledAndRotated = rotation.scaledBy(x: scale, y: scale)
//Transforming the Item respective to the distance from center
matchImageView.transform = scaledAndRotated
if gestureRecognizer.state == .ended {
if matchImageView.center.x < (view.bounds.width/2 - 100) {
animateImageToSide(target: CGPoint(x: view.bounds.width - 200, y: matchImageView.center.y))
matchImageView.alpha = 0
}
if matchImageView.center.x > (view.bounds.width/2 + 100) {
animateImageToSide(target: CGPoint(x: view.bounds.width + 200, y: matchImageView.center.y))
matchImageView.alpha = 0
}
//Reset the scaling variables and recentering the Item after swipe
rotation = CGAffineTransform(rotationAngle: 0)
scaledAndRotated = rotation.scaledBy(x: 1, y: 1)
matchImageView.transform = scaledAndRotated
matchImageView.center = CGPoint(x: view.bounds.width/2, y: view.bounds.height/2)
}
}
I am sorry if the resetting part is irrelevant for you, but im not sure if this could cause this behavior.
And this is my current Animationmethod :
func animateImageToSide(target:CGPoint){
UIImageView.animate(withDuration: 0.5, delay: 0, options: .curveLinear, animations: {self.matchImageView.center = target}) { (success: Bool) in
self.updateImage()
self.fadeInImage()//This is where i set the alpha back to 1
}
}
I am not sure if a CGPoint is what i need to use.
The current behavoir of the image is very weird. Most of the time it snaps to a specific place, regardless of the targetposition. Maybe my attempt on this is entirely wrong.
Thanks for your help !
