Clipboard UX in Expo apps — copy and paste without flooding users with iOS's paste banner
When you wire up copy and paste with expo-clipboard, iOS's paste permission banner can fire constantly and quietly erode trust. Here's exactly when the banner appears, and how hasStringAsync lets you gate a Paste button without ever reading the contents.
Handling iOS Limited Photo Library Access in a Rork (Expo) App
Handle iOS limited photo library access (selected photos only) correctly in a Rork (Expo) app. Covers the three states of full / limited / denied, designing a screen that works from the selected subset, and a path to add more photos, all with working code.
Building a Live Barcode and Text Scanner in Rork Max with VisionKit's DataScanner
Add a live barcode and text scanner to your Rork Max native Swift app using VisionKit's DataScanner. Covers the SwiftUI bridge, availability handling, throttling repeated detections, and on-device verification with working code.
Import the User's Own Image From the Files App in a Rork App, Without the URL Going Stale
Pull images from the Files app or iCloud Drive and the URL you picked goes invalid moments later. Here is how expo-document-picker, security-scoped URLs, and a reliable copy into your sandbox actually work, with running code.
Why Wallpapers Look Dull on Device: Taming Display P3 in the Delivery Pipeline
The same wallpaper looked dull once set on device. The culprit was a mix-up between wide-gamut Display P3 and sRGB. Beyond embedding profiles, here is how to tell whether the pixels are truly wide-gamut, a pre-delivery gate script, and the Android wide-color story, across six wallpaper apps.
Your Daily Reminder Stops Firing After a Couple of Weeks — iOS's Invisible 64-Notification Cap
When a daily reminder built with Rork (Expo) goes silent after a while, the cause is usually iOS's 64 pending-notification limit. Design a repeating calendar trigger for fixed messages and a rolling reschedule for daily-changing content, with working code that survives DST and multiple reminders.
Designing Rork Max Iterations So You Don't Burn Through Credits
Rork Max generates native Swift for you, but regenerating on impulse drains credits astonishingly fast. Estimate how many regenerations each screen will take, separate structural prompts from polish prompts, and draw a clear line for what to hand-edit instead. From an indie developer who ships to the store, here's how to treat credits as a budget.
Staging Wallpaper Packs Before the First Launch: Where Rork Max and Background Assets Fit
Content-heavy apps tend to greet new users with an empty grid. Background Assets downloads content out-of-band, ahead of the first launch. Here is how I implement it in Rork Max's native Swift, a domain Rork (Expo) cannot reach easily, plus how I decide when it is worth it.
Building a WeatherKit App with Rork Max — The Auth and Attribution Pitfalls
When you add WeatherKit to a native Swift app generated by Rork Max, the first walls are authentication and attribution. Here is the workflow I confirmed: token handling, rate limits, and the mandatory data-source display.
Putting a Working Button in a Rork App's Widget — Implementing App Intents So a Tap Acts Without Opening the App
How to put a button in a Rork-generated Expo app's widget that changes state without launching the app. We wire App Intents and WidgetKit together through an App Group, all the way to reloadTimelines — including the two places I lost real time.
Validating StoreKit 2 Subscriptions Server-Side: Granting Access Without Trusting the Device
To stop 'I paid but the feature won't unlock' and 'still usable after canceling,' you need a design that does not trust the device's verdict and settles entitlements on the server. Covers StoreKit 2 signed transactions, verification with the App Store Server API, and state sync via App Store Server Notifications V2, from real indie monetization.
Actually Delivering 'It Updates Without Opening' in Expo — A Realistic Background Task Design
Building 'content refreshes every morning' into a Rork-generated Expo app runs into iOS background execution being far less dutiful than you expect. Here is a minimal expo-background-task setup plus a design that doesn't break when the task never runs.
