Couldn't get a list of tags. Unexpectadly did not find the new dependency in the package graph. Package could not be resolved Xcode 16.1

Question

I want to add packages like SnapKit, Resolver, etc. Actually, it doesn't matter what package I want to add - the same result. Even adding a local package. Here is an error error: Couldn't get a list of tags. Unexpectadly did not find the new dependency in the package graph: sourceControl(identity: snapkit, location: SwiftPM.SPMPackageDependency.SourceControlLocation.remote(SwiftPM.SPMSourceControlURL(sourceControlURL: https://github.com/SnapKit/SnapKit.git)), requirement: 5.7.1 – Next Major)

Steps that didn't help:

1. Clear Xcode’s Derived Data and Package Caches Manually:

• Quit Xcode,
• rm -rf ~/Library/Developer/Xcode/DerivedData,
• rm -rf ~/Library/Caches/org.swift.swiftpm,
• xcodebuild -resolvePackageDependencies -disablePackageRepositoryCache,
• git config --global tag.forcesignannotated false,
• swift package update

2. Delete and Re-add the Dependencies
3. Disable Package Caching Temporarily
4. Verify GitHub Access and Authentication
5. Check Network and GitHub Status (using git clone - it works!)
6. Restart laptop
7. List item

Xcode 16.1 macOS 15.1 (Intel Core i7) iOS 18.0

UPDATE: You can fix the issue by updating to SourceTree version 4.2.10. No further actions needed

It's an issue related to SourceTree. In version 4.2.9, they added a setting to the .gitconfig file that's breaking SPM.

Citing @clopex:

Basically you need to run command in terminal: open ~/.gitconfig then remove: [safe] bareRepository = explicit save it and that is
