This pull request introduces a new GitHub Actions workflow for continuous integration (CI) targeting the Compose Multiplatform TimePicker module. The workflow automates building and testing across multiple platforms (Android, WebAssembly, Desktop, and iOS) to ensure code quality and compatibility.

New CI workflow for multiplatform build and test:

  • Added .github/workflows/integration-build-test.yml to define a CI pipeline that builds and tests the :datetimepicker module on Android, WebAssembly, Desktop (JVM), and iOS platforms.
  • Configured platform-specific build and test steps, including Android SDK setup, iOS simulator booting, and platform-appropriate Gradle tasks for each target.
  • Set up concurrency controls and permissions to optimize workflow runs and security.…icker across multiple platforms

Summary by CodeRabbit

  • Chores
    • Established automated continuous integration and testing infrastructure for consistent builds and validation across multiple platforms.

Walkthrough

A new GitHub Actions CI workflow is added that runs automated builds and tests for a Compose Multiplatform TimePicker project across multiple platforms: Android, WebAssembly, Desktop, and iOS. The workflow executes on main branch pushes and pull requests.

Changes

Cohort / File(s) Change Summary
CI Workflow for MPP TimePicker
.github/workflows/integration-build-test.yml
Adds GitHub Actions workflow with two jobs: linux-builds (Android, WASM, Desktop targets with Gradle matrix) and ios-build-and-test (iOS Simulator setup). Configures JDK 17 (Temurin), Android SDK, iOS Simulator (iPhone 15), and runs platform-specific Gradle build/test tasks.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

  • Verify Gradle task correctness for each platform (assembleRelease, wasmJsBrowserDistribution, desktopJar, etc.)
  • Confirm Android SDK setup (platforms, build-tools versions) is compatible with project requirements
  • Validate iOS Simulator configuration and runtime selection logic
  • Check that JDK 17 Temurin and Gradle caching are appropriate for the project

Poem

🐰 Hop-hop, the workflow's set,
Android, WASM, Desktop—no sweat!
iOS simulator boots with glee,
Our TimePicker CI machine!
Tests run swift, the builds stay green! 🎉

The sdkmanager command uses || true to suppress errors, which could mask real installation failures. Additionally, the second command yes | sdkmanager --licenses || true will always succeed even if licenses fail to accept. Consider using proper error handling or at least logging the results:

run: |
  sdkmanager "platform-tools" \
             "platforms;android-34" \
             "build-tools;34.0.0"
  yes | sdkmanager --licenses

If you intentionally want to continue on errors, consider adding comments explaining why failures are acceptable.

The iOS runtime extraction logic may be fragile. The sed command expects a specific format and the extracted runtime string may not match what xcrun simctl expects. Consider using a more robust approach:

LATEST_IOS=$(xcrun simctl list runtimes | grep "iOS" | tail -n 1 | awk '{print $NF}')
echo "Using iOS runtime: $LATEST_IOS"

Or use a specific iOS version to ensure consistency across CI runs.

Using || true to suppress errors when creating and booting the simulator could hide actual failures. If the simulator fails to boot, the iOS tests will fail anyway but without clear diagnostic information. Consider checking the exit status and providing better error messages:

if ! xcrun simctl create "CI-iPhone15" "iPhone 15" "$LATEST_IOS"; then
  echo "Simulator already exists or creation failed"
fi
if ! xcrun simctl boot "CI-iPhone15"; then
  echo "Simulator already booted or boot failed"

48-50: Document or centralize hard-coded Android API and build-tools versions.

Android API level (34) and build-tools version (34.0.0) are hard-coded here and will require manual updates as Android toolchains evolve. Consider:

  • Extracting these to a shared gradle configuration (e.g., gradle.properties or buildSrc) for consistency with your build scripts.
  • Adding a comment documenting the rationale (if intentionally pinned).
  • Adding a periodic maintenance reminder if versions need to stay current with Android releases.

1-17: Workflow configuration looks good.

Trigger conditions, concurrency controls, and minimal permissions are appropriately configured.


54-81: Gradle build tasks are well-structured.

Platform-specific tasks and consistent use of gradle/gradle-build-action@v3 look good. The matrix strategy efficiently covers all three Linux targets.


108-114: Gradle tasks look appropriate.

The iOS build and test tasks are well-configured, pending resolution of the simulator boot issues flagged earlier.

⚠️ Potential issue | 🔴 Critical

Remove error suppression from critical SDK setup commands.

The || true patterns on lines 50–51 mask failures in SDK installation and license acceptance, allowing the workflow to proceed with incomplete or failed setup. This defeats CI safety guarantees.

Replace these commands with explicit error handling, or remove || true to fail fast on problems:

       - name: Install Android build tools
         if: matrix.target == 'android'
         run: |
-          sdkmanager "platform-tools" \
-                     "platforms;android-34" \
-                     "build-tools;34.0.0" || true
-          yes | sdkmanager --licenses || true
+          sdkmanager "platform-tools" \
+                     "platforms;android-34" \
+                     "build-tools;34.0.0"
+          yes | sdkmanager --licenses

If occasional transient failures are expected, use a retry mechanism (e.g., retry action or script-level backoff) instead of silently ignoring all errors.

installation and license acceptance lines silently swallow errors with `||
true`; remove the `|| true` suffixes so failures cause the job to fail fast, and
replace with a simple retry wrapper if transient failures are expected (e.g., a
small shell loop that retries sdkmanager commands N times with sleep/backoff and
exits non-zero on final failure) or use a dedicated retry action; also ensure
the `yes | sdkmanager --licenses` command is allowed to surface errors rather
than being forced to succeed.

⚠️ Potential issue | 🟠 Major

Validate iOS simulator setup and remove error suppression.

The iOS simulator boot sequence masks failures with || true (lines 103–104) and uses fragile regex parsing (line 101) that could fail silently. Additionally, line 105 appears to be debugging output.

Issues:

  • If simulator creation or boot fails, tests will still run, likely against stale or missing simulator state, causing cryptic failures later.
  • The regex parsing sed -E 's/.*iOS ([0-9]+\.[0-9]+).*/iOS \1/' breaks if xcrun output format changes.
  • No validation that simulator boot actually succeeded before proceeding to tests.
  • Line 105 xcrun simctl list | head -n 50 looks like debug output.

Suggested improvements:

       - name: Boot iOS Simulator (iPhone 15)
         run: |
           LATEST_IOS=$(xcrun simctl list runtimes | grep "iOS" | tail -n 1 | sed -E 's/.*iOS ([0-9]+\.[0-9]+).*/iOS \1/')
           echo "Using iOS runtime: $LATEST_IOS"
-          xcrun simctl create "CI-iPhone15" "iPhone 15" "$LATEST_IOS" || true
-          xcrun simctl boot "CI-iPhone15" || true
-          xcrun simctl list | head -n 50
+          xcrun simctl create "CI-iPhone15" "iPhone 15" "$LATEST_IOS" || xcrun simctl delete "CI-iPhone15" 2>/dev/null || true
+          xcrun simctl boot "CI-iPhone15"
+          # Verify simulator is booted
+          sleep 2
+          xcrun simctl list | grep "CI-iPhone15" | grep "(Booted)" || (echo "Simulator failed to boot" && exit 1)

Alternatively, consider using a well-maintained action like futureware-tech/simulator-action or similar to abstract this complexity.

steps suppress failures with "|| true", use a fragile sed regex to pick the

the run instead of swallowing errors (remove "|| true"), (2) select the runtime
robustly by parsing JSON from `xcrun simctl list runtimes --json` (or validate
the extracted runtime exists), (3) after creating and booting the simulator
check its state in a retry loop with a timeout and exit non‑zero if it never
reaches "Booted", and (4) remove or gate the `xcrun simctl list | head -n 50`
debug output; alternatively replace the whole sequence with a maintained GitHub
Action such as futureware‑tech/simulator-action to handle creation, boot and
validation.
