Xcode – Swift Package Manager stuck on loading screen forever

SPM loads indefinitely as seen below. I cannot add any packages.

Whether I enter a URL, or don’t enter a URL, this screen is loading forever.

Have tried deleting DerivedData folder (~/Library/Developer/Xcode/DerivedData) as well as SPM caches (~/Library/Caches/org.swift.swiftpm/), does not help.

Have made sure that I’ve committed my code to a git repository, and followed the advice here.

This is the first package I’m adding—I can’t add any packages, generally.

This problem exists for all my Xcode projects.

    I had the same problem and was able to fix it by removing all my source control accounts under Xcode -> Setting -> Accounts and adding them back.

    I faced the same problem in Xcode 16.1. This solution worked for me, but I need to repeat it every time I add a new Swift package (SPM):

    1. Close Xcode completely. Ensure it’s not running in the background.
    2. Open the Terminal and run the following command to remove cached Swift Package references: plutil -remove IDESwiftPackageAdditionAssistantRecentlyUsedPackages ~/Library/Preferences/com.apple.dt.Xcode.plist
    3. Reopen Xcode and your project. You should now be able to add a new Swift Package without any issues.
