Failed to resolve dependencies Dependencies could not be resolved because no versions

We do not have a 1.1.0 release tagged yet; the repository's current default branch is downstream from the 1.1 release branch, so the README is documenting a setup that isn't live yet.

To use Swift Collections as a dependency, you need to set your expected version number to one of the existing release tags, as in .upToNextMinor(from: "1.0.5").

(To test unreleased features, you can also use a branch-based spec such as .branch("release/1.1"), or .branch("main") -- however, such specifications should never be used in production, as these development branches are, by definition, unstable: things can arbitrarily change, break or get removed from these branches, without notice.)

I'll see if I can switch the default branch to release/1.0. Failing that, it'd likely be best to change the README on main back to recommend the 1.0 versions.
