Just a Line: Resurrected
I always thought Google's Just a Line experiment[1] was crazy cool and recently wanted to revisit it. But it hadn't been updated in 7 years So I upgraded all of the dependencies (including the latest version of Swift 5), added SwiftLint and SwiftFormat, and got it (mostly) working again! Hope you have some fun with it- help welcome there's still more to do! [1] https://experiments.withgoogle.com/justaline
Just a Line: Resurrected launched on July 1, 2025 with 5 votes and more than 75% of that year's launches. The site was still online in September 2026, 1 year on.

I started working on this back in 2019, mostly as a design idea. Over the last month I made a big push to make it 100% usable and replace C# in all my personal projects. I now feel it's solid enough to gather feedback from other developers. If you take it for a spin, I hope you enjoy it and send your thoughts!

A Swift app I made in 4 months with no prior experience2023 · apps.apple.com · ▲9I have always dreamed of learning Swift and creating apps for iOS, but I never found the motivation to do so. I was scared by the complexity and the learning curve of programming with UIKit and Storyboard. I thought they were too complicated and too boring for me. But then I discovered SwiftUI, the new framework for building user interfaces for Apple platforms. I was captivated by its simplicity and elegance. I watched some videos and read some articles about it and I was blown away by what it could do. I decided to give it a shot and see if I could learn it and make something with it. I set…
- BGBlop – Game I’ve made while I was learning Swift (iteration #2)2015 · playblop.com · ▲14
In previous series: https://medium.com/@ivanpashenko/how-one-designer-was-learning-swift-cc2d99658895 https://news.ycombinator.com/item?id=8556056 I've got very useful feedback from HN community previous time. Thanks a lot guys! What was done: - Changed the name (now it is searchable in the App Store by the name) - Slowmo action to slow the game down for 15 sec - In app purchase (slowmos) - Pause button works now as it suppose to work - Location achievements (Don't forget to allow location service) - Bugfixes

Trickle - Magic Canvas ▲1,064Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production. Why is a canvas better? Most AI tools today rely on linear chats or text prompts. We believe that limits creativity and clarity. Canvas changes the game. 1. Every version & page at a glance. Each page and sub-page lives on a timeline. You can quickly browse, edit, and preview progress like a living, visual document — no more digging through chat logs or scattered states. 2. The canvas is the context. Unlike linear chats, you can…

Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…

Hi HN - I made a site that takes a UK postcode, grabs the local MP's information and generates an AI mockup of what their ID might look like. It's a small, silly protest at the stupidity of the Online Safety Act that just came into force. edit - My open AI credits got hugged to death, please use a known postcode (like one from Kier Starmer's constituency, WC2B6NH) in the meantime.
