SwiftUI 点击空白处隐藏键盘

第一种方法：

UIApplication.shared.windows.forEach { (window) in
       if window.isKeyWindow {
           window.endEditing(true)
       }
   }

第二种方法：

UIApplication.shared.windows.first?.endEditing(true)

在空白处点击，先生成底部背景使用ZStack包裹

ZStack{
            Color.white
                .frame(width: ScreenWidth, height: ScreenHeight, alignment: .center)
                .onTapGesture {
                     UIApplication.shared.windows.forEach { (window) in
                          if window.isKeyWindow {
                               window.endEditing(true)
                           }
                  }
            }
        }

这里的Color相当于UIView

let window = SceneDelegate().window
let ScreenWidth = window?.bounds.size.width
let ScreenHeight = window?.bounds.size.height
