是否有一个 Swift 属性，例如为协议设计的@nonobjc？
Is there a Swift attribute, such as @nonobjc designed for protocols?
我想写一个 PAT，我不关心 Obj-C 互操作性。 属性听起来很完美，但它仅适用于变量和方法。
任何类似的隐藏 Obj-C 协议的东西？
您似乎误解了 @nonobjc 属性的用途：
来自docs:
nonobjc
Apply this attribute to a method, property, subscript, or initializer
declaration to suppress an implicit objc attribute.
如果您进一步向下滚动页面，它会告诉您哪些内容将具有隐式 objc 属性：
The compiler implicitly adds the objc attribute to subclasses of any class defined in Objective-C. However, the subclass must not be generic, and must not inherit from any generic classes. [...] The objc attribute is also implicitly added in the following cases:
- The declaration is an override in a subclass, and the superclass’s declaration has the objc attribute.
- The declaration satisfies a requirement from a protocol that has the
objc attribute.
- The declaration has the
IBAction, IBSegueAction, IBOutlet, IBDesignable, IBInspectable, NSManaged, or GKInspectable
attribute.
这不包括协议，因此协议永远不会隐式公开给 Objective-C。这意味着您不需要协议上的 nonobjc 属性来抑制协议上的隐式 objc。默认情况下，协议不会暴露给 Objective-C，除非您用 @objc.
