import uikit

class aboutview: uiview{

@iboutlet var aboutview: uiview! @iboutlet weak var studiotxt: uilabel!  @iboutlet weak var closebtn: uibutton!  var studiotxtto : cgfloat  override init(frame: cgrect) {     super.init(frame: frame)     initializeviews() }  required init?(coder adecoder: nscoder) {     super.init(coder: adecoder)     initializeviews() }  private func initializeviews(){     bundle.main.loadnibnamed("aboutview", owner: self)     addsubview(aboutview)      studiotxtto = self.studiotxt.frame.origin.y     self.studiotxt.frame.origin.y = self.studiotxt.frame.origin.y + 55 }  @ibaction func onin(_ sender: any) {     in() }  func in(){      uiview.animate(withduration: 0.5, delay: 0, usingspringwithdamping: 0.7, initialspringvelocity: 0.0, options: .curveeaseinout, animations: {      self.studiotxt.frame.origin.y = self.studiotxtto      }, completion: { _ in         //     }) }

}

i need save origin y peropertie of label create animation, error in super.init(frame: frame) , super.init(coder: adecoder) studiotxtto

you need provide initial value studiotxtto, example change definition to:

var studiotxtto : cgfloat = 0.0
