ios - Facebook Swift SDK : loginManager Type of expression is ambiguous error

Question

我正在使用以下代码将 facebook 登录添加到 UIButton 操作:

func facebookButtonClicked(sender: UIButton) {
    let loginManager = LoginManager()

    loginManager.logIn([.PublicProfile], viewController : self) { loginResult in
        switch loginResult {
            case .Failed(let error):
                print(error)
            case .Cancelled:
                print("User cancelled login")
            case .Success(let grantedPermissions, let declinedPermissions, let accessToken):
                print("Logged in")
        }
    }
}

Xcode 抛出以下错误:

Type of expression is ambiguous without more context

对于 [.PublicProfile] 部分。

知道我在这里做错了什么吗？

最终的解决方案是这个:

 let loginManager=LoginManager()
    loginManager.logIn(readPermissions: [ReadPermission.publicProfile], viewController : self) { loginResult in
        switch loginResult {
        case .failed(let error):
            print(error)
        case .cancelled:
            print("User cancelled login")
        case .success(let grantedPermissions, let declinedPermissions, let accessToken):
            print("Logged in")
        }
    }

Facebook 还没有更新自己的代码示例...
