一个充满<FIRInstanceID/WARNING>的控制台 - Xcode 8/iOS10

Question

我在Xcode 8/iOS 10/Swift 3中遇到Firebase问题.试图让Firebase Analytics全部设置好.但是在iOS10中,控制台会记录来自Firebase的大量WARNING日志.当我在模拟器中运行iOS 9.3时,这些都不会发生.我按照此处所述的确切步骤操作:https://firebase.google.com/docs/analytics/ios/start

这是日志的样子:

<FIRAnalytics/INFO> Firebase Analytics v.3402000 started
<FIRAnalytics/INFO> To enable debug logging set the following application argument: -FIRAnalyticsDebugEnabled
<FIRAnalytics/INFO> Successfully created Firebase Analytics App Delegate Proxy automatically. To disable the proxy, set the flag FirebaseAppDelegateProxyEnabled to NO in the Info.plist
<FIRInstanceID/WARNING> Failed to remove checkin auth credentials from Keychain Error Domain=com.google.iid Code=-34018 "(null)"
<FIRInstanceID/WARNING> Error failed to remove all tokens from keychain Error Domain=com.google.iid Code=-34018 "(null)"
<FIRInstanceID/WARNING> FIRInstanceID AppDelegate proxy enabled, will swizzle app delegate remote notification handlers. To disable add "FirebaseAppDelegateProxyEnabled" to your Info.plist and set it to NO
<FIRInstanceID/WARNING> STOP!! Will reset deviceID from memory.
<FIRInstanceID/WARNING> Failed to fetch default token Error Domain=com.firebase.iid Code=6 "(null)"
<FIRInstanceID/WARNING> STOP!! Will reset deviceID from memory.
<FIRInstanceID/WARNING> Error removing keypair status: -34018
<FIRInstanceID/WARNING> Unable to remove RSA keypair
<FIRInstanceID/WARNING> Unable to generate keypair.
<FIRAnalytics/WARNING> Failed to get InstanceID: Error Domain=com.firebase.iid Code=-34018 "(null)"
<FIRInstanceID/WARNING> Failed to fetch default token Error Domain=com.firebase.iid Code=501 "(null)" UserInfo={msg=Missing device credentials. Retry later.}
<FIRInstanceID/WARNING> Failed to retrieve the default GCM token after 5 retries

我也得到以下错误,大约每30秒弹出一次(而错误最重要的是不重复):

<FIRInstanceID/WARNING> STOP!! Will reset deviceID from memory.

在发布之前,我做了研究,发现如果在功能中启用Keychain Sharing,WARNING日志可能会消失.然而,我对此感到厌倦,因为没有给出其他文件或解释.我不知道这是否只是掩盖错误,或者这是否是一个安全的解决方案.

请告知最安全的方法来补救所有这些警告日志.谢谢

只是更新一下，当使用 Xcode 8.2+ 版本的模拟器时，这些错误不应再出现在最新版本的 Firebase 中。模拟器存在一个问题（实际上有几个），并且 InstanceID 中的日志记录过于激进。
