Ионная подача имеет ошибку типографской ошибки в & ldquo; node_modules/@angular/core/src/render3/definition.d.ts”

Я использую это небольшое расширение Swift 3:

extension UIView {

  func fadeIn(duration: TimeInterval = 0.5,
              delay: TimeInterval = 0.0,
              completion: @escaping ((Bool) -> Void) = {(finished: Bool) -> Void in }) {
    UIView.animate(withDuration: duration,
                   delay: delay,
                   options: UIViewAnimationOptions.curveEaseIn,
                   animations: {
      self.alpha = 1.0
    }, completion: completion)
  }

  func fadeOut(duration: TimeInterval = 0.5,
               delay: TimeInterval = 0.0,
               completion: @escaping (Bool) -> Void = {(finished: Bool) -> Void in }) {
    UIView.animate(withDuration: duration,
                   delay: delay,
                   options: UIViewAnimationOptions.curveEaseIn,
                   animations: {
      self.alpha = 0.0
    }, completion: completion)
  }
}
