Lesson 3 of 38 steps

CI basics with swift test and artifacts is a free Swift Academy lesson on CoddyKit. This is lesson 3 of 3. Any 3 lessons of this learning path are free to read in full — after that, CoddyKit PRO unlocks every lesson, plus hands-on practice with a built-in code editor and a 24/7 AI tutor. It is part of the Swift Academy learning path, and your progress syncs across the web and the CoddyKit app. The Swift Academy course includes 3 lessons in total.

What CI does

Your CI should run on every push and tag:

  • Build & Test with SwiftPM
  • Create release artifacts
  • Upload on tags

SUT for tests

CI will build the package and run tests against your code (SUT). Keep functions small and testable.

// Example SUT and testable logic used by CI.
// In real projects, this lives in Sources/ and Tests/.
// Here we only show the code idea.

public struct Math {
    public static func add(_ a: Int, _ b: Int) -> Int { a + b }
}

print("Demo SUT ready: Math.add(2,3) =", Math.add(2,3)) // 5

Core CI commands

Use swift build to compile and swift test (often with --parallel) to run tests. Add a release build for shipping.

// Typical CI steps (illustrative):
//   swift --version
//   swift build
//   swift test --parallel
//   swift build -c release
//
// Fail fast: any non-zero exit stops the job.
print("CI steps: build → test → release build")

Create artifacts

After a release build, package binaries (or sources) into a small archive to upload as a release asset.

// Create a release binary and zip it (examples):
//   swift build -c release
//   zip app-macos.zip .build/release/app
//
// Or for libraries, zip the source or attach an XCFramework if applicable.
print("Artifacts: zip files from .build/release for distribution")

Speeding up builds

Caching tips:

  • Cache .build folder between runs
  • Pin dependencies with versions
  • Keep tests fast (tiny sleeps or none)

Tag-triggered releases

Use a tag-triggered job to produce official artifacts for versions like v1.2.0.

// Release pipeline idea:
// - Trigger on tags: refs/tags/v*
// - Build & test
// - Produce artifacts
// - Upload artifacts to the release
//
// Keep the tag name consistent (e.g., v1.2.0).
print("Tip: run a special pipeline on tags to publish artifacts")

Use swift test

Recap

Recap: In CI, run swift build and swift test, then create a release build and zip artifacts. Trigger publishing on tags and cache .build to speed up runs.
