Issue Description and Steps

I used to include JWT via CocoaPods for my framework but we are migrating it over SPM for easier internal usage.
We are currently using the latest beta 3.0.0-beta.14 but unfortunately, it is currently impossible to include it via SPM.

Source of the problem

I tried to find the source of the problem and it seems that the Package.swift is not available in the beta releases of this framework.

Solution ?

Could you make the Package.swift available for beta releases ? It would make it easier for SPM users to include your framework, as we would not be forced to use only officially released versions (which is possible via CocoaPods).
If you don't want to add this file to your beta releases, when are you planning you release the 3.0.0 version ? It would help us delay our SPM migration according to your planning.

Thank you in advance

Best regards

PS

This is Package.swift dependencies :

and this is the error that XCode is throwing at me :
