Your Rork Max Health App Misses Overnight Steps — Designing Background Delivery When HKObserverQuery Dies Silently
In a native Swift health app generated by Rork Max, data recorded while the app is closed never arrives — and it's almost always because HKObserverQuery's background delivery stopped without a word. Here's how to isolate the layer that broke and an observation layer you can drop in as-is.
Direct Device-to-Device Sharing in Rork Max Apps — The Local Network Permission Trap That Makes MultipeerConnectivity Fail Silently
How to add serverless, nearby device-to-device sharing to a native Swift app generated by Rork Max. It works in the simulator but no peers ever appear on real devices — and the culprit is almost always a silent Local Network permission failure.
Making Your Rork Max App Resilient to Dropped and Restored Connections: Offline Detection and Retry with NWPathMonitor
Build networking that survives a lost signal in your Rork Max native Swift app with NWPathMonitor. Detect offline states, respect Low Data Mode and cellular, and auto-resend queued work on reconnect — all with working Swift code.
Keeping Downloads Alive After Your Rork Max App Is Killed: Background URLSession Design and Relaunch Handling
How to design downloads in a Rork Max native Swift app so transfers continue in the OS daemon even after the app is suspended or terminated. Covers relaunch wiring, resumeData recovery, and measured isDiscretionary behavior with working code.
Protecting Ad eCPM in Your Rork Max App: Designing ATT Pre-Permission Priming
For iOS apps built with Rork Max, ad revenue swings heavily on your ATT opt-in rate. Here is how to design a pre-permission priming screen, implement it in SwiftUI, measure the opt-in rate, and order AdMob init correctly.
Building SharePlay in Rork Max's Native Swift — Keeping Two Screens in the Same State
Implementation notes on building SharePlay with GroupActivities in Rork Max's native Swift — moving two screens through the same state over FaceTime. Covers declaring the GroupActivity, joining a GroupSession, syncing state with GroupSessionMessenger, handling latency and conflicts, catching up late joiners, and the boundary for bridging from React Native, with the pitfalls I actually hit.
Before You Reach for Tap to Pay on iPhone in a Rork Max App — Eligibility, Choosing a Payment Provider, and a Realistic Design
Implementation notes for judging, from a business angle, whether you can put Tap to Pay — accepting in-person payments on an iPhone alone — into a Rork Max app. Covers the organization-account and entitlement requirements, why you need a payment provider (PSP), the split between ProximityReader and the PSP, and a realistic path for an indie developer, told candidly.
Building a Song-Recognition App with ShazamKit in Rork Max's Native Swift
Implementation notes on building a song-recognition app with SHManagedSession in Rork Max's native Swift. Covers the difference from hand-rolling AVAudioEngine, designing the idle / prerecording / matching states, using prerecording to improve initial accuracy, and the boundary design for bridging from Expo — with the pitfalls I actually hit.
Long-Form On-Device Transcription with SpeechAnalyzer in Rork Max's Native Swift
Implementation notes on rebuilding long-form, offline transcription with iOS 26's SpeechAnalyzer and SpeechTranscriber after hitting the walls of SFSpeechRecognizer. Covers model asset downloads, feeding audio through an AsyncStream, drawing volatile vs. final results, and the boundary design for Rork Max native code and bridging from Expo — with the pitfalls I actually hit.
Making the Block Screen Feel Like Your Own App — ShieldConfiguration and Button Handling in Rork Max
Replace the plain gray shield that screen-time apps show with something that speaks in your app's voice. This walks through swapping the UI with a ShieldConfiguration extension and controlling the buttons with ShieldAction, wired into a Rork Max native setup.

Implementation notes on solving the 'local notifications stay silent in Silent Mode and Focus' problem with iOS 26's AlarmKit. Covers authorization, scheduling a countdown, the Live Activity for the Lock Screen and Dynamic Island, and listing active timers in Swift — plus the boundary design for Rork Max native code and bridging from Expo, with the pitfalls I actually hit.
Screening Images On Device Before They Appear — Notes on SensitiveContentAnalysis
Implementation notes on blocking inappropriate images before they render, right on the device, for apps that handle AI-generated or user-submitted photos. Covers calling Apple's SensitiveContentAnalysis framework from Swift and wiring it into Rork Max native code or an Expo native module, with the pitfalls I actually hit.
