Code completion is dead. Autonomous, codebase-wide edits are here. 🤯 The Cursor team just dropped a massive deep dive into the evolution of "self-driving codebases". A fascinating look at the future of the IDE: 🔗 go.peterfriese.dev/towards-self-d… #CursorIDE #AI

AI can write code faster than you. But can you read it that fast? 🧠 As we shift to Agentic AI, we are trading Technical Debt for "Cognitive Debt". @margaretstorey wrote a brilliant piece on the mental toll of maintaining AI-generated codebases: 🔗 go.peterfriese.dev/how-generative… #SoftwareEngineering #AI

AI coding assistants are great, but they lack discipline. @galdawave fixed this by building the "Pickle Rick" extension for the Gemini CLI. It acts as a hyper-intelligent, arrogant persona that enforces a strict, iterative dev loop. Brilliant. 😂 🔗 go.peterfriese.dev/pickle-rick-ex…

@rseroter @GoogleAIStudio @googlemaps I’ve always wanted to have a hotel tracker that tells me if I’ve had the same room before. I thought that’s pretty niche, but maybe not so much…?

Just built my first app in the updated @GoogleAIStudio. It uses Firestore for data storage, Auth to verify users, and @googlemaps integrations. Smooth builder workflow! Great job team. I'll document my steps shortly.

Gemini 3.1 Flash‑Lite runs faster and cheaper than Flash - but nobody's talking about *when* you should actually use it. 🤔 @patloeber breaks it down and demonstrates 7 key use cases: go.peterfriese.dev/3nozdu

I wanted to see if "Agentic Engineering" was just hype. So I tried it. 👨‍💻 I live-streamed building a Swift version of the Mozilla Readability SDK from scratch using the Gemini CLI and the Pickle Rick extension. 🥒 Watch the chaos (and success) unfold: 🔗 go.peterfriese.dev/i-let-an-ai?s=…

App Store Connect can be a pain. But @rudrank just built an AI agent skill for the ASC CLI to automate your deployments! 🚀 iOS release pipelines just got a massive AI upgrade: 🔗 go.peterfriese.dev/app-store-conn… #iOSDev #SwiftLang

Human DX optimizes for discoverability. Agent DX optimizes for predictability. 🤖 Justin Poehnelt (creator of the Google Workspace CLI) explains why you need to rewrite your CLIs for AI agents: 🔗 go.peterfriese.dev/you-need-to-re… #DevTools #AgenticEngineering

Rebuilding a core framework usually takes a team months. Steve Faulkner just rebuilt Next.js with AI in a single week. 🤯 If you have solid specs & tests, massive refactoring is no longer a pipe dream. Fascinating read: 🔗 blog.cloudflare.com/vinext/ #AgenticEngineering #NextJS

Stop tethering your iPhone to Xcode just to check battery drain. 🛑 Vladimir Babin shared a hidden trick to measure app energy impact directly on-device using the iOS Developer menu! 🔋 🔗 linkedin.com/posts/ios-mast… #iOSDev #SwiftLang

The era of writing every line of code yourself is ending. But are we just trading Technical Debt for "Cognitive Debt"? 🤔 Issue 96 of Not Only Swift covers Agentic Engineering, rebuilding Next.js with AI, and my own Swift SDK live stream. Featuring @galdawave, @margaretstorey & more! 🔗 peterfriese.dev/newsletter/iss…

I had way too much fun to create the thumbnail for today's livestream... Join me in 15 minutes to see if I can build an entire SDK using @geminicli and Pickle Rick! youtube.com/watch?v=MT2faG…
