I am trying to add a Swift Package from a private Gitlab repository to my Xcode 16 project, and it fails. First symptom is Unable to load the Read Me in the Xcode SPM package browser. And when I add the package, I get a repo.git could not be resolved error. I've used ProxyMan to sniff the network calls issued by Xcode, and it looks like my Gitlab credentials are not provided as part of the GET request when, for example, Xcode tries to fetch the README.md file from the repository. And when I try to add the package, there are no HTTP network calls issued by Xcode at all. I have tried adding a Gitlab account to Xcode's Accounts preference pane, and entering the repository's credentials directly when adding the package. Both yield the same result. Here's a screen capture of Xcode trying to fetch the README: https://share.cleanshot.com/FNRHm6fq I am unable to test this in Xcode 15, as I have upgraded my Mac to Sequoia and Xcode 15 can't be installed on this version of macOS. I have submitted FB15370281 for this issue.
