React Native 0.81 just dropped with a game-changing performance boost: iOS builds up to 10x faster. But there's a catch that'll affect every Android developer.
Scott Southerland from Thumbtack just shared what most iOS teams won't tell you: migrating to Swift 6 took 16+ months and broke their entire test suite. Here's the battle-tested playbook they wish they'd had.
Tripadvisor's mobile team was drowning in nearly-identical UI components. Their server-driven UI framework promised speed but delivered the opposite.
Reddit's mobile team had zero professional CI experience. Then they cut build times in half and transformed developer happiness.
Ninikvatchantiradze from Teknasyon Engineering reveals why most iOS teams are measuring performance completely wrong. Your simulator tests and CPU averages are hiding the issues that make users uninstall your a...
Ninikvatchantiradze from Teknasyon Engineering reveals why most iOS developers are measuring app performance completely wrong. If you're only testing locally or tracking basic CPU metrics, you're missing what's...
Max Roche from Grindr Engineering just solved one of SwiftUI's most annoying problems: why do custom components require massive initializers while Apple's native views stay clean and simple?
Kcrdissanayake from PickMe reveals how their team migrated an 8-year-old ride-hailing driver app from UIKit to SwiftUI while maintaining iOS 15 compatibility. The bold rewrite wasn't just about modern code—it w...
Meta just shared how they moved billions of daily users to their new on-device ML framework. The performance gains are substantial.
Brian Terczynski from Thumbtack tracked down a brutal Android OOM bug that was crashing apps at startup—and the culprit wasn't a memory leak. It was hiding in plain sight: their SQLite queries.
Duolingo's iOS team turned a boilerplate problem into a Swift Macros showcase. Their codebase grew, but developer friction didn't have to.
Airbnb's SwiftUI features were re-rendering way more than they should. The culprit? SwiftUI's hidden diffing algorithm was working against them.
Callstack explores how React Native is becoming the unexpected bridge between traditional mobile development and the Web3 ecosystem. Building decentralized apps just got a lot more practical.
Apple's Password Monitoring team just shared something remarkable: they rewrote their entire backend service from Java to Swift and the results are staggering. This isn't a client-side migration story—it's bill...
Majid Jabrayilov explores how microapps architecture can solve the scaling nightmare that plagues large iOS codebases. His approach turns monolithic apps into composable, independently testable modules.
Maxwell Elliott and Connor Wybranowski from Tinder turned what seemed like a 12-year project into a 6-month sprint. Their secret? Letting the compiler do the heavy lifting instead of manually untangling 150,000...
Tripadvisor's iOS team was drowning in coordinator spaghetti. Navigation paths were impossible to trace, and even senior engineers couldn't debug their own flows.
Braulio Ríos built a production-ready guitar tuner app using React Native that processes audio in real-time with near-native performance. Here's how he combined TypeScript, C++, Swift, and Kotlin to solve a pro...
Jacob Bartlett from Jacob's Tech Tavern puts SwiftUI scroll performance under the microscope. Can it really hit 120fps with complex infinite feeds, or does the magic come at too high a cost?
Swift just made a major statement at FOSDEM 2025, and it's not just about iOS anymore. The language is pushing hard into memory safety, embedded systems, and even Java interoperability.
