Reset Modules as an Xcode local package with tests in CI by mokagio · Pull Request #24518 · wordpress-mobile/WordPress-iOS

mokagio · 2025-05-05T06:04:44Z

Description

#24511 successfully addressed the issue of duplicated packages in the target selection.

Unfortunately, it resulted in all local packages (those from Modules/ that is) no longer being accessible to the unit tests runner—see internal discussion in p1746169066574499/1745343713.430699-slack-C08HQR4C2TS

This PR propose a different fix, achieved by re-adding Modules/ as a local package not a package dependency, following the instructions from https://developer.apple.com/documentation/xcode/organizing-your-code-with-local-packages.

This setup maintains the single result in the target search...

...while also allowing for Modules/ to run as dedicated schemes or as part of a test plan

Also notice, we have so many tests (and warnings when running them!) that the logs don't show the first tests that run, but if you check the XML report, you'll see that indeed we are running all previously disabled tests

Next steps

Rename WordPressUnitTests.xctestplan to Keystone.xctestplan—to do in dedicated PR to avoid diff noise here
Ensure all module targets that have tests run as part as Keystone.xctestplan
Add dedicated schemes for focused package development

Modules/Package.swift

-        .testTarget(name: "WordPressFluxTests", dependencies: ["WordPressFlux"], swiftSettings: [.swiftLanguageMode(.v5)]),
+        .testTarget(
+            name: "WordPressFluxTests",
+            dependencies: ["WordPressFlux"],
+            exclude: ["WordPressFluxTests.xctestplan"],
+            swiftSettings: [.swiftLanguageMode(.v5)]
+        ),


I added this to see how WordPressFluxTests would run tests with standalone scheme.

Interestingly, I tried using a copy-paste friendly exclude: ["*.xctestplan"], pattern, but it failed to find the file.

My autogenerated scheme picks up the test plan:

However, I got an unlock prompt when I edited it (but no xcsheme change in the project, possibly because the scheme might be in Modules/.swiftpm) so I'd be curious to know if you see it too...

WordPress/WordPress.xcodeproj/project.pbxproj

-			relativePath = ../Modules;
-		};
-/* End XCLocalSwiftPackageReference section */
-


I think the difference between this and the previous setup (pre #24511) is that we no longer have any local swift package reference as a dependency for WordPress.

My guess is that, whichever way it ended up like that, the duplicated reference—as a local module in the workspace and as a package reference—is what resulted in the duplicated entries shown in the #24511 description.

This looks good. Let's switch back to the standard "drag-n-drop" approach. I left a couple of small comments.

Modules/Package.swift

    name: "Modules",
    platforms: [
        .iOS(.v16),
+        .macOS(.v14), // Here just to avoid errors when building directly with `swift build`


Is this addition necessary? Most of our packages do not support macOS and won't compile with it as a target.

I find it handy to have just so swift build throws legitimate errors with the code rather than with the versions.

In particular, it was necessary to run the WordPressFlux tests via swift test. However, as I try to reproduce, I can't get past some UIKit errors, which I find odd when focused on WordPressFlux, but don't have bandwidth to investigate.

Removed it.

Thanks! Yeah, I'd remove it since it doesn't support macOS.

WordPress.xcworkspace/contents.xcworkspacedata

 <?xml version="1.0" encoding="UTF-8"?>
 <Workspace
   version = "1.0">
+   <FileRef


Let's add Modules to a project and not a workspace. We we going to remove the workspace.

We we going to remove the workspace.

I started looking at it #24534

.gitignore

-#
-# Ignore the Package.resolved file. The packages source of truth is the
-# resolved file generated by the Xcode workspace.
-Modules/Package.resolved


I thought you had to use ...ace/xcshareddata/swiftpm/Package.resolved managed by Xcode? Modules/Package.resolved isn't, or is it? How did you get it to work? When you open the Xcode project, does it use pins from Modules/Package.resolved?

...ace/xcshareddata/swiftpm/Package.resolved → Modules/Package.resolved

Apologies @kean this change surprised me a bit and I should have preempted your question writing about it.

Before

Modules was part of the workspace. When Xcode detected changes in Modules/Package.swift, it triggered the packages resolution and updated the resolved file in the workspace xcshareddata folder.

After

Modules is part of the project, but is not a dependency of the project:

When Xcode detects a change in Modules/Package.swift, it triggers the packages resolution and updates Modules/Package.resolved.

I guess that if we were to add additional package dependencies to the project Xcode would then re-introduce the workspace resolved file.

When Xcode detects a change in Modules/Package.swift, it triggers the packages resolution and updates Modules/Package.resolved.

I verified this by switching color-studio from pointing to a branch to a commit. The screenshot below shows Xcode highlighting the change in the gutter and the package resolution running.

35e360b tracks the changes and the .resolved update.

Given OCLint is something we should drop soon, because it's only for Objective-C and we want to reduce that code surface.

Locking dependencies to commits makes updating them a bit more burdensome, but at least it makes the update intentional and not automatic and surprising. This change was done to test Xcode's behavior in monitoring `Modules/Package.swift` and updating `Modules/Package.resolved`. See #24518 (comment)
