Mobile Release Engineering

Field-tested release engineering across iOS, Android, and macOS: promotion gates, build economics, signing custody, immutable artifacts, and user-installable proof.

Why Mobile Releases Should Start From Tags, Not Every Commit

Use mobile release tags to separate unprivileged verification from protected signing and distribution jobs for iOS and Android.

The Hidden Cost Model Behind macOS CI Runners

Compare macOS CI runners using demand timing, allocation policy, production proof, and a dated 24-hour break-even calculation.

How to Cut a 30-Minute Mobile Pipeline Without Skipping Proof

Shorten a 30-minute mobile pipeline with early verification, parallel native builds, concrete manifests, and safer cache boundaries.

Sign, Package, and Notarize the Exact macOS Artifact Users Install

Make macOS signing and notarization auditable with path checks, content manifests, inside-out signing, and installed-app verification.

How to Publish Immutable Release Artifacts From a Private Repository

Publish immutable release artifacts with create-only version keys, OIDC credentials, canonical digests, and ETag-guarded JSON discovery.
