“访问钥匙串时发生错误”当使用Firebase登录时 [英] "An error occurred while accessing the keychain" when signing in using Firebase

问题描述

背景：

我正在使用Firebase进行应用登录。
我正在使用通过电子邮件地址功能登录。
开始使用新的xCode测试版并将代码更新到Swift 3之后，错误就开始了

你可以在这里看到这个问题的原型： https://bitbucket.org/gilosborne/firebasetest

错误：

当我尝试登录时，出现访问钥匙串时发生错误的错误。

我没有以任何方式使用Apple Keychain，我相信这里指的是keychain的提及： https://firebase.google.com/docs/auth/ios/errors

当我输入错误的电子邮件地址时，我得到正确的错误说电子邮件地址不匹配。而创建一个新的帐户仍然有效。我只有在正确登录现有电子邮件地址时才会出现错误。

在查看上面的firebase文档后，我打印了以下内容：
print（error？.userInfo [NSLocalizedFailureReasonErrorKey]）

和

更多，并得到这些控制台日志

可选（SecItemAdd（-34018））

$ b $ n

我对iOS开发非常陌生，但是我花了好几个小时或者Google搜寻，试图解决这个问题，并取得了零进展。

再说一次，一切正常。我所做的只是更新到Swift 3.0，这开始发生。任何帮助真的很棒，谢谢！

ps。对不起，如果我错过了任何东西，这是我第一次发布。

Background:

I'm using Firebase for my apps login. I am using the login via email address functionality. The error started after starting to use the new xCode beta and updating the code to Swift 3

You can see a prototype of the problem here: https://bitbucket.org/gilosborne/firebasetest

The error:

When I try to log in I get the error, "An error occurred while accessing the keychain".

I am not using Apple keychain in any way, I believe it is referring to the mentions of keychain here: https://firebase.google.com/docs/auth/ios/errors

When I enter the email address wrong i get the correct error saying the email address doesn't match. And creating a new account still works also. I only get the error when login in correctly with an existing email address.

After looking into the firebase documentation above more I printed: print(error?.userInfo[NSLocalizedFailureReasonErrorKey])

and

print(error?.userInfo[NSUnderlyingErrorKey])

to try and learn more and got these console logs

Optional(SecItemAdd (-34018))

nil

I'm very new to iOS development, but I have spent hours or googling and racking my brain trying to fix this and have made zero progress.

Again, everything was working just fine. All I did was updated to Swift 3.0 and this started happening. Any help would be really awesome, thank you!

ps. Sorry if I missed anything, this is my first time posting.

解决方案

Try turning on the Keychain Sharing in Capabilities of your projects' target. that worked for me. Keychain Sharing
