skipping cache due to an error: https://github.com/apple/swift-numerics.git: The repository could not be found. Make sure a valid repository exists at the specified location and try again.

How do I fix this?

Try adding https://github.com/apple/swift-numerics without the .git extension

Yeah, I see this a lot in my projects, too. The problem is that it's not a warning, it's an error, so I can't update the packages for my own project while something within them relies on this project.

@tonyarnold not an ideal "solution", but I had the same issue, caused by using swift-algorithms. My solution was to comment out all the code using the package, commenting out the dependency from my Package.swift, updating all my packages, and finally undoing all the commenting out.

Luckily for me that was just ~50 lines of code that was fairly nicely isolated.

[tonyarnold]

Thanks for the suggestion, @Iikeli. Unfortunately in my project, Swift Numerics is an indirect dependency of something else, and that something else is used in too many places to comment them out.

I wonder if this is actually a SwiftPM issue, rather than something that this repository has done wrong?

I have seen many posts about this issue on other packages.
All changes discussed here will be in your file ~/.gitconfig

Fix 1
Change forceSignAnnotated to false. Source
As Taras pointed out we're configuring Git so that it does not require GPG signatures for annotated tags on a global level for the user.
git config --global tag.forcesignannotated false

Fix 2
Apparently if you're using SourceTree, remove these lines. Source

[safe]
    bareRepository = explicit

or change it to:

[safe]
    bareRepository = *

Fallback
In my case, I still couldn't get it work, I realized I couldn't even push changes to my repo because I didn't have set the gpg.format

[gpg]
	program = gpg
	format = openpgp

If this wasn't your issue, just try to commit and push changes through the Terminal and fix the errors you see on it, with all previous changes done, it should be working by now.
