Hi @Kaur-Pushpinder,

Can you help us with the steps to reproduce ?

And is the issue #863 also opened by someone from your team ?

[Kaur-Pushpinder]

@desusai7 this is a random issue, there are no specific steps. just one info it is coming in renewAuth.

[Kaur-Pushpinder]

@desusai7 any update on this?

I am also experiencing similar issue, though I've been able to determine that in my case it breaks on NSKeyedUnarchiver

[path/ios.app]"
)}" UserInfo={NSDebugDescription=value for key 'root' was of unexpected class 'A0Credentials' (0x105529ff8) [/path/ios.app/Frameworks/Auth0.framework].
Allowed classes are:
 {(
    "'A0Credentials' (0x101562e50) [path/ios.app]"
)}}

Is there any particular reason why NSKeyedUnarchiver is used instead of Swift's JSONDecoder?

@desusai7 Could you let us know if this is something your team is aware of an looking into?

[desusai7]

Hi @theolampert, @Vaidios,

Thank you for sharing more details on the issue and raising a PR to address this, we will look into it and get back to you !

[theolampert]

@desusai7 Thanks!

[theolampert]

@desusai7 As an interum solution would you accept a PR that made the credentialManager's decoding method throwing so that those of who've noticed this could try to eliminate the cause and gather more info?

This would be a breaking change.

Hi @Vaidios,

In your case, there seem to be two A0Credentials classes, one in the Auth0 framework and one in your app bundle.

Hi @theolampert,

You can create a custom storage type conforming to CredentialsStorage that proxies to SimpleKeychain, and use it to log any Keychain errors.

E.g.

let credentialsManager = CredentialsManager(authentication: authentication, 
                                            storage: ProxyStore())

You can see how Auth0.swift uses SimpleKeychain here: https://github.com/auth0/Auth0.swift/blob/master/Auth0/CredentialsStorage.swift#L30 Specifically, you'd need to catch the error here instead of using try?.

That is because Auth0.swift v2.0.0 came out before SimpleKeychain v1.0.0 (in which the decoding method became throwing), and thus, this solution was needed to avoid a breaking change in Auth0.swift.

Hi @Kaur-Pushpinder,

You can use the method suggested above ☝🏼 to log the underlying Keychain error.

[Widcket]

Please report back what the underlying Keychain error was if you're still experiencing this issue.

Thanks for the reply, I'll take a look at doing that and report back anything.
