Announcement: main is now the default branch

[1ec5]

main is now this repository’s default branch. Most development takes place on this branch, and releases will be based on this branch. For more context on the branch renaming, see github/renaming.

Like most GitHub repositories, this repository originally maintained master as the default branch. During the v1.0 release cycle, we maintained main as an alias for the master branch, keeping both branches in sync using FF-merging. Now that v1.0 has been released, we’ve made main the default branch. All open pull requests now target the main branch; please target it going forward.

We’re aware that some developers have historically pointed their Podfiles or Cartfiles to the master branch. To avoid breaking your workflow or continuous integration builds, we’ve avoided deleting the master branch for now. However, that branch will only be kept in sync with the main branch on a best-effort basis. Eventually we expect to let that branch fall by the wayside just like the old swift3 branch.

This is also a good reminder that you should link to code within a repository using a permalink that specifies a specific commit or at least a specific branch, so that the link continues to function after a branch gets renamed or, more commonly, after a file gets renamed or code get shifted around.
