Pull request Check for `CollectionCoordinator` rather than self on composed-swift/ComposedUI

Using embedded collection views with each one using a CollectionCoordinator would cause an infinite loop in responds(to:).

Maybe it's better to check in responds(to:)? I don't know if there are other scenarios this could happen in.

Running UI Tests on Mac Catalyst

While working on the 2.0 update for Gathered I have been trying to develop the app multiple platforms simultaneously. SwiftUI will solve this problem in the future, but I wish to support some OS versions that SwiftUI does not support.

As part of this I have been creating UI tests to test performance, but ran in to an issue when running the UI tests on macOS using Mac Catalyst:

Running tests...
The bundle “PerformanceXCTests” couldn’t be loaded because it is damaged or missing necessary resources. Try reinstalling the bundle.
(dlopen_preflight(...): no suitable image found.  Did find:
	...: code signature in (...) not valid for use in process using Library Validation: mapped file has no Team ID and is not a platform binary (signed with custom identity or adhoc?))

Pull request Add GitHub actions on composed-swift/Composed

This is a copy/paste from https://github.com/JosephDuffy/Persist/, with a couple of small tweaks:

  • Only tests iOS; macOS, tvOS, and watchOS were removed
  • Coverage is not uploaded to Codecov; I don't have permission to add the project
  • Xcode 11.5 is used; this is the latest stable version
  • v2 of the cache action is used; this is the latest stable version

It will do the following:

  • Perform a release when a tag starting with v is pushed
    • v0* or v*- (e.g. v1.1.0-rc1) will be marked as pre-release
  • Build and upload docs to the gh-pages branch as part of releases
  • Run tests against iOS when a commit is pushed

Note that the cache is not as useful as it could be right now; Swift likes to rebuild things based on inodes so the cache is largely (maybe entirely) discarded, but will be useful in a future Swift release.

You'll need to create an orphaned gh-pages branch for the docs since I don't have permissions. I don't think it needs an initial commit, although maybe you can't push an empty branch? I've never tried.

My Swift Package Manager Release Workflow

I am currently maintaining numerous Swift Packages that don't receive a constant flow of updates, but do receive updates when new Swift updates come out, or as I think of useful additions.

To ensure that I can make some of these less frequent updates without too much friction and with confidence in their correctness I rely heavily on GitHub Actions, which I'll go over in this blog post.
