Handing Over an App — What an App Store Transfer Carries, and What You Rebuild
A practical look at App Store Connect app transfers when selling or moving an app: the eligibility criteria, what carries over (ratings, subscribers, iCloud data), what you rebuild (TestFlight, APNs, merchant IDs), and the three places users actually feel the change.
Shipping Notifications Without Asking First — Provisional Authorization in Rork Apps, and the Expo Snippet That Quietly Undoes It
iOS lets you start delivering notifications with no permission dialog at all, via provisional authorization.

When a Poisoned Cache Crashes Your App on Every Launch — Designing a Safe-Mode Boot Your Users Can Escape On Their Own
When a persisted cache goes bad and the app crashes at the same spot on every launch, the only option left to the user is to reinstall. This article designs a safe-mode boot for Expo (React Native): the app counts its own early crashes, confirms a launch only once it becomes interactive, and resets just the dangerous state in graduated steps.
