The problem of garbled emojis is ugly, so I'll try using Claude Sonnet 4.5 with Xcode's Coding Assistant from the web version of Claude.

I'm using Claude.ai's Pro plan and paying $20 per month but I receive this message and have to wait another three hours. I try to convince myself that it's a good thing that I can rest or do something else during this time.

I just noticed that App Store Connect quietly created a really nice promo video for my first app: Music Map. I had no idea they did that automatically; it turned out beautifully! apps.yacchi.com/MusicMap/

What I have achieved today: - Setting my sub-domain to point to my GitHub page. - Created my app landing/support page. - Fixed bugs in my app and released it. All thanks to Claude Al. What a time to be alive!

Apps that handle location data always raise privacy concerns. That's why the safest approach is to build your own. That's why I created this app. I'd like to thank Paul Hudson @twostraws for providing the excellent Hacking With Swift tutorial. apps.apple.com/app/music-map…
