Animations with safeAreaLayoutGuide (Swift 5) - swift

Question

I would like a smooth animation of this view whenever the search bar is selected and deselected. Right now it's choppy:
Heres my code below in the searchResultsUpdater. From what I understand, these functions should handle the animations, I'm not sure what's wrong here:
func updateSearchResults(for searchController: UISearchController) {
//MapView moves up when search bar is selected
if searchController.isActive == true{
UIView.animateKeyframes(withDuration: 0.25, delay: 0.0, options: UIView.KeyframeAnimationOptions(rawValue: 7), animations: {
self.mapView.frame.origin.y=self.view.safeAreaLayoutGuide.layoutFrame.origin.y
},completion: nil)
}
//MapView moves down when cancel button is selected
if searchController.isActive == false{
UIView.animateKeyframes(withDuration: 0.25, delay: 0.0, options: UIView.KeyframeAnimationOptions(rawValue: 7), animations: {
self.mapView.frame.origin.y=self.view.safeAreaLayoutGuide.layoutFrame.origin.y
},completion: nil)
}
}
Any help is appreciated, thank you!

I found the solution. Originally I had the CGRect for the mapView frame in viewDidLayoutSubviews():
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
//layout to fit frame of view
mapView.frame = CGRect(x: 0, y: view.safeAreaInsets.top, width:
view.frame.size.width, height: view.frame.size.height -
view.safeAreaInsets.top)
}
I moved it to viewDidLoad(), and now it works:
override func viewDidLoad() {
super.viewDidLoad()
//add gesture recognizer for mapView
mapView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(mapViewAnimation)))
//layout to fit frame of view
mapView.frame = CGRect(x: 0, y: view.safeAreaInsets.top, width:
view.frame.size.width, height: view.frame.size.height -
view.safeAreaInsets.top)
}
I also added a gesture recognizer instead so that the searchResultsUpdater wouldn't be so cluttered:
//handle the animation for mapview
#objc func mapViewAnimation(){
UIView.animateKeyframes(withDuration: 0.25, delay: 0.0, options:
UIView.KeyframeAnimationOptions(rawValue: 7), animations: {
self.mapView.frame.origin.y =
self.view.safeAreaLayoutGuide.layoutFrame.origin.y
},completion: nil)
}
If anyone knows why it didn't work when I had the CGRect in didLayoutSubViews() feel free to let me know. Thanks!
