Describe the problem you'd like to have solved

Compiling in Swift 6 language mode results in concurrency errors like problems with Sendability of Credentials as discussed in this forum issue from 2022 https://community.auth0.com/t/credentialsmanager-credentials-and-sendability/95271

Describe the ideal solution

The SDK should be updated to compile without errors when used in Swift 6.

Alternatives and current workarounds

Importing with @preconcurrency may be a workaround but could be hiding issues in concurrent code.

Hi @honus,

By "Compiling in Swift 6 language mode", do you mean changing the Swift version for the Auth0.swift target, or just your app's target?

Also, are you getting errors (compilation fails), or just warnings?

[honus]

App's target. Errors.

Unfortunately my project isn't in a state where I can easily reproduce this issue right now. When I get a chance I'll try to get you more specific examples of problems.

I just tried with the sample app (cleaning the cache beforehand) and was able to compile successfully:
