It's really nice to see Tuist replacing CocoaPods and its demo setup! 👏

I left some comments around Bundle extension tweaks that we can make, along with some Tuist updates to begin pulling in the test targets.

johnnewman-square · 2025-07-07T20:24:00Z

Internal/EnglishDictionary/Sources/EnglishDictionary.swift

In this EnglishDictionary.swift file, there's a Bundle extension that we can tweak now that CocoaPods are gone - the extension can now always return the .module bundle. I've tested this by opening the "Fuzz Testing" demo in the Demo app.

We could also make a similar change to the listableUIResources property in Bundle+ListableUI.swift.

When the ListableTests target is pulled in by tuist, we can make this change to the Bundle extension in StableRNG.swift too.

Demo/Project.swift

+import ProjectDescription
+
+let project = Project(
+    name: "Demo",


I wonder if we should rename this to ListableDevelopment to match naming conventions in other projects, like Workflow?

definitely recommend that — make sure to get Workspace.swift too

Demo/Project.swift

+        .target(
+            name: "DemoTests",
+            destinations: .iOS,
+            product: .unitTests,
+            bundleId: "com.listable.demo.tests",
+            deploymentTargets: .iOS("15.0"),
+            sources: ["Test Targets/**"],
+            dependencies: [
+                .target(name: "Demo")
+            ]
+        ),


This target is having trouble pulling in tests on my machine, but I was able to get tests to appear after replacing this target with the following ones. There is a bit more work for supporting the unit tests that require an app host. Sharing this as a start:

.target( name: "ListableTests", destinations: .iOS, product: .unitTests, bundleId: "com.listable.ListableTests", deploymentTargets: .iOS("15.0"), infoPlist: .default, sources: ["../ListableUI/Tests/**"], resources: ["../ListableUI/Tests/Resources/**"], dependencies: [ .external(name: "ListableUI"), .target(name: "EnglishDictionary"), .target(name: "Snapshot") ] ), .target( name: "BlueprintUIListsTests", destinations: .iOS, product: .unitTests, bundleId: "com.listable.BlueprintUIListsTests", deploymentTargets: .iOS("15.0"), sources: ["../BlueprintUILists/Tests/**"], resources: [], dependencies: [ .external(name: "BlueprintUILists"), .external(name: "BlueprintUICommonControls"), ] ), .target( name: "Snapshot", destinations: .iOS, product: .framework, bundleId: "com.listable.snapshot", deploymentTargets: .iOS("15.0"), sources: ["../Internal/Snapshot/Sources/**"], resources: [], dependencies: [.xctest] ),

This is working well, nice work! There are a few final items that I wanted to iron out before merging:

The IdentifierChangedViewController is missing imports to Foundation and UIKit. This controller was just merged into main.
Scripts/generate_docs.sh is having issues finding the ListableUI scheme.
There is a Snapshot-Unit-Tests target in Listable's main branch with a few unit tests for the internal library. We might want to pull that into Tuist as well.

johnnewman-square

Nice! Thanks for making those updates.

I think there's some work remaining to ensure tests run and docs can still be generated, looks good overall though.

.github/workflows/run_tests.yml

-      - name: Pod Install
-        run: bundle exec pod install --repo-update
+      - name: Test All
+        run: tuist test --path Demo --os ${{ matrix.sdk }} -resultBundlePath TestResult


You need to specify the scheme for tuist as the last arg. It's currently just emitting a usage message and not actually running tests!

Thanks for catching this! I could swear I put the workspace name in there. tuist only allows one scheme in the parameters, so my options were either to run three separate commands for the different test schemes and merge the individual xcresult files or to use the workspace name instead so that it runs all the tests in the workspace.

Demo/.package.resolved

did tuist generate this one? I don't see it on other repos. Maybe see what happens if you just delete this one.

Demo/Project.swift

+import ProjectDescription
+
+let project = Project(
+    name: "Demo",

Demo/Project.swift

+            destinations: .iOS,
+            product: .app,
+            bundleId: "com.listable.development",
+            deploymentTargets: .iOS("15.0"),


you've probably already seen, but in the other projects I defined a bunch of extensions to abstract common things like deployment targets and bundle IDs.

watt · 2025-07-15T20:13:20Z

Package.swift

            exclude: ["EnglishDictionary.podspec"],
            resources: [
                .process("Resources"),
            ]
        ),
        .target(
            name: "Snapshot",
-            path: "Internal Pods/Snapshot/Sources"
+            path: "Internal/Snapshot/Sources"
        ),
        .testTarget(
            name: "SnapshotTests",


Do these work from Package.swift? I think you may be forced to remove the test targets from Package.swift and move them to Project.swift due to the app host requirement. (Which IMO is fine and maybe better since you can move the internal targets out of here entirely.)

I had to remove the test definitions as well since they had a dependency on the internal pods. Given that the tests are run as part of Tuist, is there any need to specify the unit tests in Package.swift? I see them defined in Package.swift in the Blueprint repo.

-gem 'cocoapods'

-gem 'jazzy'


You'll need to keep the Gemfile for jazzy, which is currently used by generate_docs.sh.
