We have several private Swift packages in our project, hosted in private Git repos. In Xcode 14, when the credentials were wrong or missing, it showed a very helpful "Edit Credentials" link next to the error message (see Xcode 14 screenshot):
In Xcode 15 that link is missing and it's not clear how to fix the credentials for the given package:
We use the link all the time. Please don't remove it in Xcode 15 :) Thank you! I've filed feedback FB12424445 about this, but it's not clear if it was transmitted successfully (see https://twitter.com/jfahrenkrug/status/1672143906094325760).
