我可以登录,但是当谷歌窗口打开时,如果我点击完成,应用程序就会崩溃。有人能帮帮我吗?提前致谢。
我已经在这个应用程序上工作了一段时间,这是最后一步。 我得到的错误是
fatal error: unexpectedly found nil while unwrapping an Optional value
我找到了解决办法
func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) {
if error == nil
{
auth(authentication: user.authentication)
}
else
{
print(error.localizedDescription)
}
}
