ios - AuthDataResult 类型的值没有成员 providerID

Question

我正在经历这个令人沮丧的问题。令人恼火的是，他们为 Firebase 进行了这样的更新，几乎没有特定文档。我收到同样的错误:“AuthDataResult”类型的值没有成员“providerID”。这是我的代码:

                if let user = user {
                    if self.segmentedControl.selectedSegmentIndex == 0 {
                        let userData = ["provider": user.providerID] as [String: Any]
                        DataService.instance.createFirebaseDBUser(uid: user.uid, userData: userData, isDriver: false)
                    } else {
                        let userData = ["provider": user.providerID, USER_IS_DRIVER: true, ACCOUNT_PICKUP_MODE_ENABLED: false, DRIVER_IS_ON_TRIP: false] as [String: Any]
                        DataService.instance.createFirebaseDBUser(uid: user.uid, userData: userData, isDriver: true)
                    }
                }

问题是代码中名为 user 的对象不是 FIRUser，而是错误指示的 AuthDataResult。

let authdataresult = // the thing you were calling user
let user = authdataresult.user  // this is a FIRUser
let providerData = user.providerData  // this is FIRUserInfo
let providerId = providerData.providerId
