Coding in Swift and coffee are my fuel. ☕️💻

Stanford research just confirmed what many of us suspected: AI models are dangerously sycophantic. They agree with users even when users are wrong — especially on personal advice. As an indie dev using AI daily, this is a real problem worth designing around. #AI #IndieDevLife

Apple turns 50 this April 🎂 Indie devs like me owe a lot to what they've built — Xcode, SwiftUI, the App Store. Hard to imagine building ChargeChill and BiteCam on any other platform. #Apple #indiedev #iOS

Running a local 14B model on a $500 GPU with a smart inference pipeline — 74.6% on LiveCodeBench vs Claude Sonnet's 71.4%. No API, no cloud, code stays on your machine. Wild. 🤯 https://t.co/I9lz824LfB #AI #MachineLearning #indiedev

Swift 6.3 just dropped! Highlights: official Swift SDK for Android, new @c attribute for C interop, and a unified Swift Build engine across all platforms. The language really is going everywhere 🚀 #Swift #iOS #indiedev

[Filip Růžička @froseio]

ARC-AGI-3 just dropped — the new AI benchmark for agentic intelligence. Humans score 100%. Best frontier AI? 0.26%. No rules, no instructions — agents must explore, figure out the game, and adapt on their own. $2M in prizes. The gap is real. 🤖 #AI #AGI

OpenAI is shutting down Sora. Launched with massive hype, had a Disney deal just 3 months ago — now gone. Too expensive to run, too many restrictions, and Chinese video models caught up fast. Wild how quickly the AI landscape moves 🎬

the indie dev loop: build feature → break CI → write the fix → automate so it never happens again → add the automation to the backlog too 😅 somehow the app still ships

Weekend drives hit different when range anxiety isn't part of the plan ⚡🚗 ChargeChill helps you find EV chargers wherever you're headed. v2.0.0 out now on the App Store 🔋 #IndieApp #iOS #EV

[Filip Růžička @froseio]

watch apps are like bonsai trees — tiny, precise, and oddly satisfying to get right. been deep in watch UI this week and it hits different when a tiny wrist screen just... works ⌚🌿

[Filip Růžička @froseio]

Switched my PR reviewer from Copilot to Codex. Both are AIs, but it genuinely felt like onboarding a new team member 😄

Solo dev life is getting weird in the best way.

[Filip Růžička @froseio]

ChargeChill 2.0 is live! 🔋⚡ Finding EV chargers should be the least stressful part of your drive — so we made it smoother. Cleaner UI, faster search, better experience all around. Give it a try 🙌 #ChargeChill #EV #IndieApp #iOS

5/ It's a strange time to be an indie dev. More leverage than ever with AI tooling. But at the end of the day it's still just you, shipping, iterating, hoping it clicks with users. Still love it. 🚀

[Filip Růžička @froseio]

3/ Also switched my automated PR reviewer from Copilot to Codex. Both AI-assisted, but different strengths. Codex feels more at home with Swift/iOS patterns. Still experimenting.

[Filip Růžička @froseio]

4/ Meanwhile the watch app for ChargeChill is taking shape. Designing for that tiny screen is humbling — forces you to cut everything non-essential. Actually makes the phone app better too.

[Filip Růžička @froseio]

2/ Biggest win: when a CI check fails on a PR branch, an AI agent now reads the logs, identifies the issue, and pushes a fix automatically. Fewer 2am "why is CI red" sessions. 🙏

[Filip Růžička @froseio]

1/ Indie dev reality check: you're the developer, QA, reviewer, and release manager all at once. So lately I've been leaning hard into automation. Here's what's changed in my workflow 👇

[Filip Růžička @froseio]

One of my favorite parts of indie dev: slowly automating away the tedious stuff. CI checks, PR reviews, release notes... every little script that saves future-me 10 minutes feels like a win 🤖✨

[Filip Růžička @froseio]

iOS 26.4 RC just dropped 🚀 Along with macOS, iPadOS, watchOS, tvOS, visionOS 26.4 RC — and Xcode 26.4 RC too. Public release can't be far. Time to spin up the simulators and do one last round of testing! 🧪 #iOSDev #Apple

[Filip Růžička @froseio]

shipping a watch app feels different. the tiny screen forces you to be ruthless — every pixel has to earn its place. no room for 'maybe useful' features. honestly the best design constraint i've worked with in years 🙂⌚

[Filip Růžička @froseio]

there's something deeply satisfying about setting up CI automation that just... fixes itself. indie dev hours well spent 🤖✨ #indiedev #iosdev
