Xcode SwiftUI中的自定义Google登录按钮

我在使用SwiftUI制作自定义Google登录按钮时遇到问题。它将打开一个窗口，允许您登录，但当我尝试在文本字段中键入任何内容时，它不会键入任何内容。有人见过这个吗？这是我的应用程序代理（一些打印语句仅供我参考）：

我完全是个初学者，所以可能会犯一些愚蠢的错误。

最好使用UIViewController（由UIViewRepresentable提供）登录社交网络，这样你就可以自定义按钮，而且SwiftUI view在GIDSignIn/facebookMaya中遇到一些问题-你试过使用FirebaseUI吗？这可能是实现Firebase应用程序Google登录的最简单方法。有关如何在Swift应用程序中使用此功能的信息，请参阅和GitHub上的。而不是UIApplication.shared.windows.last？.rootViewController，请尝试UIApplication.shared.windows.first？.rootViewController更好地使用UIViewController（通过UIViewRepresentable）登录社交网络，因此，您可以自定义按钮，而且SwiftUI view在GIDSignIn/facebookMaya中遇到一些问题-您尝试过使用FirebaseUI吗？这可能是实现Firebase应用程序Google登录的最简单方法。有关如何在Swift应用程序中使用此选项的信息，请参阅和GitHub上的。而不是UIApplication.shared.windows.last？.rootViewController，请尝试UIApplication.shared.windows.first？.rootViewController
