这样编译：

import AppKit

class CustomView: NSView, CALayerDelegate {
    func layoutSublayers(of layer: CALayer) {}
}

但是，这不是：

import AppKit
import SwiftUI

class CustomView: NSView, CALayerDelegate {
    func layoutSublayers(of layer: CALayer) {}
}

这是一个错误：

... error: redundant conformance of 'CustomView' to protocol 'CALayerDelegate'
class CustomView: NSView, CALayerDelegate {}
                          ^
... note: 'CustomView' inherits conformance to protocol 'CALayerDelegate' from superclass here
class CustomView: NSView, CALayerDelegate {}
      ^

任何想法如何解决这个问题？

如果删除CALayerDelegate一致性，则不会调用委托方法。
