Despite being on Anthropic's Max plan, Claude Opus reaches its limit (too) fast using Claude Code. 🤔
My vibe coding loop: - Scope the feature with ChatGPT - Turn the chat into a PRD - Commit the PRD to the repo as Markdown - Ask Claude Code to convert the PRD into a Markdown task list - Work the list
What I love about Swift and programming in general is that it's a never-ending creative challenge. Even after 15 years of building software, I learn something new every day. AI hasn't replaced that for me. It's accelerated it. Don't see AI as a threat. See it as a multiplier.
TIL that AWS charges $0.40 per secret stored in AWS Secrets Manager. 😵💫
I'm most productive when I work/build in blocks of 45 minutes. It's sometimes tempting to keep going when you're in the zone, but a break has its benefits. More often than not, those breaks are the source of solutions and creativity. Try it out.
I've been building apps for Apple's platforms for over 15 years, and I still love it as much as ever. 😍
Time-boxing turns procrastination into progress. Set a timer. Start. You'll be shocked how much you can do in 25 minutes.
If you want to launch an MVP fast, then don't spend time reinventing the wheel. For a recent project, I leveraged @vercel , @pinecone , @triggerdotdev , and @AssemblyAI . It works like a charm.
Developers reviewing the code generated by AI before accepting all the changes.
This is wild. Apple is asking users to turn off Subscription Renewal Emails - right inside 3rd party developers apps… RIGHT AFTER A PURCHASE. This makes it feel entirely like the developer is asking to have notifications disabled instead of Apple! Bad Apple! Really doesn’t sit…
An expedited review isn't as expedited as it used to be. 🤔
Nobody who’s actually good at making money needs to sell you a course on it.
What's your go-to tool for managing (reading, replying) App Store reviews?
Xcode Cloud is convenient, but I have a strong suspicion it runs on an old Apple PowerBook.
AI is great for generating seed or dummy data. What I typically do is (1) provide a description of the project, (2) include the data model, and (3) describe a scenario. What also helps is asking whether everything is clear.
