I have similar experience as the author where I don't know the first thing about Swift but I was able to make my first iOS app[0] from start to finish on the initial release in about 3 weeks.

I think the hardest part was actually automating the release pipeline to directly upload to the App Store for a release with Test Flight.

It wouldn't have been possible without Claude's help.

Then next hard and tedious part was do a complete conversion to Android with Kotlin, which I also didn't have any experience either. That one-to-one parity was rather painful but it was done in about a month or so.

Now I just develop create features on the iOS version first and then do a parity match with the Android version after with Claude.
