下面的代码根本不工作：火力地堡Facebook帐号登录FIRUserInfo
if let rawProfile = user?.providerData["cachedUserProfile"] as? ......
Error: Cannot subscript a value of type '[FIRUserInfo]' with an index of type 'String'
我一直在努力从旧的火力地堡控制台/文件到新的更新我的项目。
但是，新用户似乎只允许在用户注册FIRUserInfo（如displayName，photoURL和电子邮件）时拉取某些内容。
任何想法如何我能够拉我以前的东西，如性别？
