取消存档 AuthState 时应用程序身份验证崩溃

Question

我正在我的 iOS 应用程序中实现应用程序身份验证库，并尝试在存档身份验证状态时清除一些警告。

'unarchiveObject(with:)' 在 iOS 12.0 中已弃用：使用 +unarchivedObjectOfClass:fromData:error: 代替

和

'archivedData(withRootObject:)' 在 iOS 12.0 中已弃用：使用 +archivedDataWithRootObject:requiringSecureCoding:error: 代替

以下工作正常，但有警告：

    private func loadAuthState() {
        guard let data = UserDefaults.standard.object(forKey: kAppAuthAuthStateKey) as? Data else {
            return
        }

        if let authState = NSKeyedUnarchiver.unarchiveObject(with: data) as? OIDAuthState {
            print("AuthState loaded. Access token: \(authState.lastTokenResponse?.accessToken ?? "DEFAULT_TOKEN")")
            self.authState = authState
            self.signedIn.update(with: .signedIn)
        }
    }

    private func saveAuthState() {
        if let authState = self.authState {
            let data = NSKeyedArchiver.archivedData(withRootObject: authState)
            
            UserDefaults.standard.set(data, forKey: kAppAuthAuthStateKey)
            UserDefaults.standard.synchronize()
            
        }
    }

更改为以下内容后，我在取消存档时崩溃（由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序，原因：“不支持响应类型“（null）”。AppAuth仅支持“代码”或“代码id_token”响应类型。'):

    private func loadAuthState() {
        guard let data = UserDefaults.standard.object(forKey: kAppAuthAuthStateKey) as? Data else {
            return
        }

        if let authState = try? NSKeyedUnarchiver.unarchivedObject(ofClass: OIDAuthState.self, from: data) {
            print("AuthState loaded. Access token: \(authState.lastTokenResponse?.accessToken ?? "DEFAULT_TOKEN")")
            self.authState = authState
            self.signedIn.update(with: .signedIn)
        }
    }

    private func saveAuthState() {
        if let authState = self.authState {
            guard let data = try? NSKeyedArchiver.archivedData(withRootObject: authState, requiringSecureCoding: false) else {
                return
            }
            
            UserDefaults.standard.set(data, forKey: kAppAuthAuthStateKey)
            UserDefaults.standard.synchronize()
            
        }
    }
