    Reaper - An open-source SDK for finding dead code

    Sentry open-sourced Reaper, an SDK for detecting dead code in iOS and Android apps through runtime analysis. Unlike static analysis tools, Reaper monitors actual user sessions to identify code that's never executed in production. The iOS version leverages Objective-C and Swift runtime metadata to track type initialization with zero runtime overhead. The Android version instruments bytecode at build time, injecting tracking calls into class initializers. Both implementations allow teams to aggregate usage data across app versions and safely identify unused code for deletion, helping manage codebase complexity and technical debt.

    Hacktivate

    Paul Hudson built Hacktivate, a capture-the-flag game teaching cybersecurity fundamentals to teens through 240 challenges covering SQL injection, cryptography, networking, and steganography. The app runs entirely locally on Apple devices using Swift and SwiftUI, featuring a sandboxed environment with simulated servers, terminals, and networks. Inspired by classic games like Syndicate and Command & Conquer, it combines retro aesthetics with practical skills like packet sniffing, hash cracking, and digital forensics. The 45,000+ lines of code include a Linux terminal emulator, web server, and various security tools, all designed to provide structured, privacy-preserving learning without external dependencies.

    Announcing Capacitor 8

    Capacitor 8 has been released with two major updates: Swift Package Manager (SPM) replaces CocoaPods as the default dependency manager for new iOS projects, and Android now includes built-in edge-to-edge support through a new SystemBars plugin that automatically handles status and navigation bar appearance. Existing CocoaPods projects remain supported, and the new SystemBars API provides fine-grained control when needed. The framework continues growing rapidly, approaching one million weekly downloads.

    Apple redefines reality (again) at WWDC25…

    Apple announced native Linux containerization for macOS at WWDC 2025, allowing developers to run containers without Docker Desktop through optimized VMs on Apple Silicon. The company introduced 'liquid glass' as their new design language for iOS 26, emphasizing transparency effects. Swift received updates including Java interoperability and C/C++ mixing capabilities. Apple downplayed AI features this year after previous struggles, while simultaneously releasing research questioning the intelligence of large language models.

    How Tinder Decomposed Its iOS Monolith App Handling 70M Users

    Tinder successfully decomposed its massive iOS monolith serving 70M users by using compiler-driven dependency analysis to create a modular architecture. The team built automated tools that extracted the dependency graph from Swift compiler data, then systematically moved files in phases starting with leaf nodes. This approach reduced build times by 78% and completed the migration in 6 months instead of an estimated 12 years, all without causing production incidents. The process involved updating dependencies, imports, access controls, and dependency injection patterns for each moved file.
