FXKeychain failed to retrieve data for key 'token', error: -34018

Same issue with iOS 10 and iPhone 7 simulator...

@bimusiek and all others getting this issue:

If you're getting this issue now, it's likely because iOS 10 now requires a new entitlement for keychain usage. Here's the fix:

Go to your project target and under capabilities add Keychain Sharing to your app. It immediately resolved my issues.

@jboulter11 Yes, you are right. I forgot to reply here after I found the solution.

Confirmed, you have to enable Keychain Sharing, however for me this is not really the solution for people that do not want to share Keychain :) However, the fault is at Apple side.

Apple are aware of it... https://forums.developer.apple.com/thread/4743#14441

UPDATE: We have finally been able to reproduce the -34018 error on iOS 8.3. This is the first step in identifying the root cause and then coming up with a fix.

As usual, we can't commit to a release timeframe, but this has affected many developers and we really want to get this resolved.

In the meantime, for a workaround, try adding a small delay in application:didFinishLaunchingWithOptions and applicationDidBecomeActive: before accessing the keychain. However, we know this hasn't worked in at least one case. Now that we have a reproducible case, I can experiment with the delay and see if I can come up with a recommended value.```

Is it only when accessing the keychain right at launch? I'm getting this well after the app launch...

Having the same issue. Is there a solution to this problem? Thanks

Having the same issue and the workaround that Apple provided with the delay is not working for me either. Hope there will be a fix in a new iOS version soon though.

Having the same issue only when running in debug mode with Xcode with the device connected to the debugger.

Having the same issue only when running in debug mode with Xcode/AppCode with the device connected to the debugger...

Same issue here in iOS 9.2.1. When device is not connected to the debugger it works ok for me.
