@_silgen_name(“方法名”) 无需桥接OC 不需要引用即可在swift内实现调用OC方法
swift判等：protocol Equatable { func ==(lhs: Self, rhs: Self) -> Bool }
associatedtype 泛型占位

Xcode(13.2.1)后版本对歧义命名有要求，例如:

class Test: UIView {
	
  public var cornerRadius: CGFloat {
        get {
            layer.cornerRadius
        }
        set {
            layer.cornerRadius = newValue
        }
     }
}

调用时候则会报错歧义。

let test = Test()
test.cornerRadius = 12

执行震动

 AudioServicesPlaySystemSound(SystemSoundID(kSystemSoundID_Vibrate))

关于CABasicAnimation动画处理
设置属性时候注意设置isRemovedOnCompletion = false,如果未设置此属性会在切换页面时导致主线程动画丢失

例子如下：

     let rotaionAniamtionAnima = CABasicAnimation(keyPath: "transform.rotation.z")
     let num:CGFloat = .pi*(-3.5)
     rotaionAniamtionAnima.toValue = num
     rotaionAniamtionAnima.duration = 2
     rotaionAniamtionAnima.repeatCount = MAXFLOAT
     rotaionAniamtionAnima.isRemovedOnCompletion = false
     backLayer.add(rotaionAniamtionAnima, forKey: "rotaionAniamtion")

例子如下：

extension UIView {
 /// 指定圆角
 ///
 /// - Parameters:
 ///   - corners: 需要实现为圆角的角，可传入多个
 ///   - radii: 圆角半径
 func extCorner(corners: UIRectCorner, radii: CGFloat) {
     let maskPath = UIBezierPath.init(roundedRect: self.bounds, byRoundingCorners: corners, cornerRadii: CGSize(width: radii, height: radii))
     let maskLayer = CAShapeLayer()
     maskLayer.frame = self.bounds
     maskLayer.path = maskPath.cgPath
     self.layer.mask = maskLayer
 }
}

	CaseIterable

enum可遵循的协议，可获取allCases属性，用于表示一个包含枚举所有成员的集合。

设置默哀模式

 private func setSilenceMode(_ vc: UIViewController) {
     let overlay = UIView(frame: vc.view.bounds)
     overlay.isUserInteractionEnabled = false
     overlay.translatesAutoresizingMaskIntoConstraints = false
     overlay.backgroundColor = .lightGray
     overlay.layer.compositingFilter = "saturationBlendMode"
     vc.view.addSubview(overlay)
     vc.view.bringSubviewToFront(overlay)
     overlay.snp.makeConstraints { make in
         make.edges.equalToSuperview()
     }
 }
