CI Pipelines for Android & iOS
Build, test and assemble both apps automatically.
CI Pipelines for Android & iOS is a free Kotlin Multiplatform Academy lesson on CoddyKit — lesson 3 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Kotlin Multiplatform Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
One Codebase, Two Pipelines
KMP shares code but still ships two apps. Good CI builds, tests and packages both Android and iOS automatically on every push.
Tests Run on the Shared Layer
Your biggest win is shared logic. Run the commonTest suite in CI so a broken rule is caught once, before it reaches either app.
./gradlew allTestsBuild the Android App
For Android, CI assembles the APK or bundle. The assembleRelease task produces the artifact your release step will later upload.
./gradlew assembleReleaseBuild the iOS App
iOS jobs must run on a macOS runner with Xcode. Linux cannot compile the Kotlin/Native framework or build the iOS app.
Cache Gradle Between Runs
Fresh runners are slow. Caching the Gradle home and Kotlin/Native dependencies across jobs avoids redownloading the world each time.
Cache CocoaPods Too
If iOS uses pods, cache the Pods folder. Skipping a full pod install on every run shaves real minutes off the iOS job.
Separate Jobs, Shared Triggers
Keep Android and iOS as separate jobs so one failing platform does not hide the other, yet both fire from the same push.
Sign Builds with Secrets
Release builds need keys. Store the keystore and certificates as encrypted secrets, never committed in the repository.
Fail Fast on Lint
Run lint and formatting checks early. Catching style and obvious bugs up front saves expensive build minutes on doomed runs.
./gradlew lint detektPublish Artifacts
Save the APK and iOS artifact from each run. Testers can grab a build directly instead of waiting for a manual export.
Branch and PR Rules
Run the full suite on every pull request and block merges until it is green, so main stays releasable at all times.
Quick Check
Recall the runner requirement for the iOS pipeline.
Recap
You ran shared tests in CI, built both apps with Android on Linux and iOS on macOS, cached dependencies, signed with secrets, and gated merges on green. ✅
