ComingUp is in 8 languages, and I don't speak any of them besides English.
No translators, no native speakers checking. AI does the first pass, then I check every string against Apple's own wording for that language.
Solo devs shipping in other languages: how are you doing it?

Are you letting your coding agents push straight to main, or does everything go through a branch and a PR?
Mine work on a branch and open a PR, and I review it before anything merges.

ComingUp's Siri answers won't be plain text. They'll show the same ticket cards you see in the app, with the days count matching what Siri says out loud.
Still on a branch, but it already feels like part of the app instead of a bolt-on.

77 followers here last Friday. 214 by Monday morning.
No tricks. The posts that did it were the ones where I asked what you're building and actually went and looked.
Still working out what to do with that. Thanks for being here 👋

I use ComingUp every day. I add things in the app, then the widget keeps them in front of me.
Plans on the same day stack up, and a tap flips through them on the Home Screen.
If you build something, use it every day. That's where you find what's missing.

Text("+\(count)") quietly ends up in your String Catalog as "+%lld", waiting to be translated.
If it's just a number, skip localisation:
Text(verbatim: "+\(count)")
Found it on ComingUp's Siri cards, where a "+2" badge was sitting in the catalog.

This is really useful. Paywalls are the bit I go back and forth on most with my own app, so a 25-minute version of 580 videos is exactly what I needed 🙌

Small things like this are what make an app feel properly finished. The icon re-forming from pixels sounds really nice 👌

Shipping weekly has helped me with this. I release most Fridays, so polish just goes in the next version instead of holding this one back. Much easier to stop fiddling when another release is only a week away.

Turning Game Boy games into an instrument is such a fun idea! Love seeing goofy little apps like this 👏

How often do you ship app updates?
I've settled into releasing ComingUp about once a week. Whatever's ready by the cut goes in, the rest waits for next week.
Weekly, monthly, or when it's done?

Something I didn't expect: about 60% of ComingUp's downloads last month came from App Stores that aren't in English.
France, Germany, Spain, Brazil, China and Japan.
Four of them don't have a single rating. So that's where my App Store work goes next.

Planned the first slice of Siri AI for ComingUp. You'll be able to ask:
"What's coming up this week?"
"How long until Mum's birthday?"
"Who's going to the gig with me?"
"What's my next event?"
Four App Intents, plus events indexed so Siri can handle related questions too.

Apple's new Xcode plugin for Claude Code beats xcodebuild and grepping logs.
It can:
• check one file for errors without a full build
• render SwiftUI previews, no build-and-run
• run named tests
• search Apple's current docs
/plugin install xcode@claude-plugins-official

I use AI to build ComingUp every day, and I still have to check its work.
It'll happily write code that runs. Knowing if it'll scale, stay secure, or fall over in six months takes experience.
That's the bit I enjoy helping newer devs with.

Ah yeah I use OpenClaw for a bit and then gave up with it.
I’ll think I’ll check it out. Was thinking of dropping ChatGPT anyway so will sub it in
