Two weeks of half-finished batch runs, and every log line said success
A job scheduled twice a day was firing once, and nothing in the logs showed it. Here is the run ledger that catches executions that never happened, plus a backlog-slope check, with real command output.
I Moved the Thumbnails Assuming the Shipped Build Would Keep Asking for the Old Path
Reorganizing image directories on the server does not reach the builds already installed on people's phones. Here is the two-way fallback that returns 200 for both the old and new paths, the ordering rule for images versus catalog, and the four checks I run through a CDN before calling a release live.
Every bulk replace exited zero. The damage was in the lines I did not delete
Run a bulk replace over generated code and the breakage lands on the neighbouring lines, not the matched ones. Here is what broke in a live project, and a dependency-free guard that checks the invariants a replace must preserve.
The Update That Failed Because a Profile Expired Three Months Ago
Apple signing assets expire quietly and nothing tells you. Here is how to count the days left with the App Store Connect API and put the audit on a weekly Cloudflare Workers cron.
Every Key You Ship Is Public: Secret Boundaries and Rotation for Rork-Generated Apps
Unzip your own .ipa, run strings, and your environment variables are right there in plain text. Here is how I sort keys into three tiers, move the dangerous ones behind an edge proxy, and keep a rotation runbook that assumes leakage.
Logging Design for Rork Apps: What to Keep and How to Redact PII
Rork-generated apps tend to scatter console.log everywhere, and when a bug appears you cannot read the part that matters. This designs structured logging, log levels, automatic PII masking, and production send control — all with code you can use as-is.
Turning Rork App Crash Reports You Can Actually Read — Field Notes on dSYM Recovery, Context Logs, and Staged Distribution
You added Crashlytics, but the stack traces are unreadable. Field notes on restoring dSYM/mapping symbols, logging the context that led to a crash, and gating distribution with App Distribution and GitHub Actions.
Where to Stop Letting Rork Fix Your Bugs: A Triage Routine for the 30% That Need You
Most bugs you hand Rork get fixed in a couple of regenerations. A stubborn minority loop forever, each fix spawning a new symptom. Here is the triage routine I use to split what to delegate from what to take over by hand, with retreat lines, regression guards, and a decision log.
Keeping Expo Push Tokens from Slipping Through the Cracks in Production
After adding re-engagement push to a Rork-generated Expo app, the delivered count came in well below the active install count. The cause was missed token updates and stale tokens left to pile up. Here is the lifecycle I settled on, with code: registration, refresh, server storage, and pruning.
Managing Store Metadata as Code with the App Store Connect API — Turning Manual Edits into a Monthly System
As the apps you ship with Rork pile up, the time spent hand-editing store descriptions and prices stops being negligible. This walks through managing metadata as code with the App Store Connect API and rolling it out across a dozen apps, including the authentication pitfalls.
Before Your Feature Flags Turn Into a Junkyard — Governing Naming, Staged Rollout, and Kill Switches Across Six Apps
Keep adding remote-config flags and within six months you have keys nobody remembers the meaning of. Here is a governance system — naming conventions, safe defaults, staged rollout, kill switches, and monthly cleanup — with the implementation from running six apps in parallel.
Shipping Wallpaper Packs Without an App Review — Versioning and Delta Delivery for Remote Assets Across Six Apps
Re-submitting your app every time you add ten wallpapers grinds operations to a halt. Here is a manifest-based versioning scheme with delta downloads, cache invalidation, and rollback — with the implementation and measured transfer savings from running six apps in parallel.
