Hi I'm trying to resize my NSPanel with spring animation but I have a position problem (the panel is not on center of screen) when I make the panel bigger (see the video) How can I fix it? Video:

func animationBigger () {
let jump = CASpringAnimation(keyPath: "transform.scale")
jump.damping = 60
jump.mass = 10
jump.initialVelocity = 10
jump.stiffness = 200.0
jump.fromValue = 1.0
jump.toValue = 2.0
jump.duration = 0.4
//self is NSPanel
self.contentView?.layer!.add(jump, forKey: nil)
self.setContentSize(bignotchSize)
}
class NotchView: NSView {
private var mouseDownSubject = PassthroughSubject<NSPoint, Never>()
var mouseDownPublisher: AnyPublisher<NSPoint, Never> {
return mouseDownSubject.eraseToAnyPublisher()
}
//Draw notch
override func draw(_ dirtyRect: NSRect) {
super.draw(dirtyRect)
drawNotch()
}
func drawNotch () {
self.layer?.anchorPoint = CGPoint(x: 0.0, y: 0.0)
let size = self.frame.size
let r: CGFloat = 15.0
let gap: CGFloat = 1.0
let notch = NSBezierPath()
notch.move(to: NSPoint(x: 0.0, y: size.height))
notch.curve(to: NSPoint(x: r, y: size.height - r),
controlPoint1: NSPoint(x: r - gap, y: size.height),
controlPoint2: NSPoint(x: r, y: size.height - gap))
notch.line(to: NSPoint(x: r, y: r))
notch.curve(to: NSPoint(x: 2 * r, y: 0.0),
controlPoint1: NSPoint(x: r, y: gap),
controlPoint2: NSPoint(x: r + gap, y: 0.0))
notch.line(to: NSPoint(x: size.width - 2 * r, y: 0.0))
notch.curve(to: NSPoint(x: size.width - r, y: r),
controlPoint1: NSPoint(x: size.width - r - gap, y: 0.0),
controlPoint2: NSPoint(x: size.width - r, y: gap))
notch.line(to: NSPoint(x: size.width - r, y: size.height - r))
notch.curve(to: NSPoint(x: size.width, y: size.height),
controlPoint1: NSPoint(x: size.width - r, y: size.height - gap),
controlPoint2: NSPoint(x: size.width - r + gap, y: size.height))
notch.close()
NSColor.black.setFill() //change to black to see the notch
notch.fill()
}```
