Swift 5.5 brought a concurrency model that actually feels like it belongs in the language. Async/await lets you reason about work that suspends and resumes without hunting through nested closures. But once you start writing real code, the sunny-day path is rarely the whole story. Things break. Networks hiccup. Payloads surprise you. This guide lays
The Case for Moving Beyond Completion Handlers If you have built or maintained a substantial iOS or macOS codebase over the past few years, you are likely familiar with the growing complexity of asynchronous programming in Swift. Nested closures, retain cycles, forgotten weak self references, and deeply indented completion handlers have been the standard tax
How to Structure a Swift Project for Long-Term Maintainability When a Swift project starts, the directory often contains a handful of files, a simple App target, and an implicit understanding among the team about where code belongs. Six months later, that same project can become a tangled web of view controllers, utility classes, and ambiguous
The Setup: What Actually Changed in February 2025 Anthropic dropped Claude 3.7 Sonnet in February 2025, and the headline feature is extended thinking mode. If you haven’t dug into this yet, here’s the stripped-down version: the model now thinks through problems step-by-step before giving you an answer, with configurable token budgets up to 128K tokens
The Quiet Revolution Nobody’s Talking About AWS dropped Aurora DSQL at re:Invent 2024, and the internet collectively shrugged. No keynote fireworks. No celebrity cameos. Just a database announcement that fundamentally changes how you should think about global consistency and multi-region architecture. That’s how you know it’s important. For fifteen years, we’ve been told to pick
The Setup: Why Code Review Got Harder (And Why That Matters) If you’ve been shipping code for more than five years, you know the unsettling feeling. Pull requests are getting larger. Complexity isn’t decreasing. Junior developers are shipping PRs with solid logic but questionable architectural decisions, and you’re staring at 47 files wondering where the
The Agent Mode Shift: What Actually Changed Let me be direct. When GitHub rolled out Copilot Agent Mode broadly in early 2025, it didn’t just add another feature to the editing toolbar. It fundamentally altered what “writing code” means in a collaborative environment. Agent Mode operates autonomously across multiple files, executes terminal commands, and iterates
The Landscape Has Shifted Faster Than Anyone Expected Three years ago, if you wanted AI-assisted coding, you basically had one choice: GitHub Copilot. It was the obvious lane, backed by Microsoft’s distribution machine and integrated into every corner of their ecosystem. Now? It’s genuinely competitive. Cursor crossed 500,000 paid subscribers by late 2025 and raised
The Hype Cycle Hits Again GitHub Copilot Workspace went into general availability in late 2025, and the marketing was hypnotic. End-to-end task completion from issue to pull request without leaving the browser. No context switching. No manual handoffs. Just describe what you want, and watch the magic happen. Over 1.8 million developers started using it
The 62-Minute Problem Nobody Talks About Let’s start with a number that should keep your security team awake at night: 62 minutes. That’s the average time an attacker now has between initial access and lateral movement inside your network. One year ago, it was 84 minutes. One year from now, it’ll probably be shorter. This
