KMP Publishing And CI

Use this skill for KMP release automation, Maven publishing, Gradle metadata, public library release, XCFramework, SwiftPM export, KMMBridge, CocoaPods migration, CI matrix design, and app-store build boundaries.

Classify Release Shape

• Private app module only.
• Internal shared library consumed by platform apps.
• Public KMP Maven library.
• Prebuilt iOS framework consumed through SwiftPM or CocoaPods.
• App-store release using shared code and native app shells.

Gates

• Maven/public library: metadata, publications, signing boundary, checkKotlinAbi when configured, target matrix, publication dry run.
• Maven Central: include POM validation and signing configuration checks when the configured publishing plugin exposes them.
• XCFramework: device and simulator slices, bundle ID, static/dynamic linkage, exported dependencies, zip/checksum, consumer import test.
• SwiftPM: generated or maintained Package.swift, checksum validation, tag/version rule, wrapper target when Swift dependencies must accompany a binary target.
• KMMBridge: artifact hosting, spm() or cocoapods() mode, versioning, and iOS consumer documentation.
• CI matrix: Android compile/test, common metadata compile/test, iOS simulator compile/link, Compose UI tests where configured, ABI/publishing dry run for libraries.
• GitHub Actions: Linux runners can cover many shared/Android tasks, but iOS builds require macOS runners. Preserve artifacts only after successful validation.

Safety

• Do not create or paste real signing secrets, Maven credentials, App Store Connect keys, keystores, provisioning profiles, or checksums from private artifacts.
• Do not publish, upload, notarize, or submit without an explicit release request.
• Keep release commands dry-run or validation-only unless the user asks to publish.

Output

For release work, provide:

• release shape
• artifact matrix
• CI tasks
• publishing gates
• secret/signing boundary
• exact validation commands
• blocker list

Useful validation tasks when configured:

• checkPomFileForMavenPublication
• checkSigningConfiguration
• publishToMavenCentral
• publishAndReleaseToMavenCentral
• ./gradlew jvmTest
• Android assemble/test tasks for Android targets
• iOS xcodebuild or Kotlin iOS simulator compile/link tasks

Use publish tasks as dry-run or validation-only unless the user explicitly requests release execution.
