问题：Equatable协议识别异常导致自定义==方法报错

问题描述

定义的NavigationDestination结构体中，object属性明确声明遵循Equatable & Hashable & Identifiable协议，但Xcode仅将其识别为Hashable & Identifiable，导致在自定义==方法中执行lhs.object == rhs.object时触发报错：Binary operator '==' cannot be applied to two 'any Hashable & Identifiable' operands

struct NavigationDestination: Hashable, Equatable, Identifiable {
    
    let object: any Equatable & Hashable & Identifiable
    let context: [String:Any]
    
    var id: String {
        return self.object.id as! String
    }
    
    static func == (lhs: NavigationDestination, rhs: NavigationDestination) -> Bool {
        return lhs.object == rhs.object
    }
    
    public func hash(into hasher: inout Hasher) {
        return hasher.combine(id)
    }
        
}
