I'm a (mainly) iOS App Developer whose mother tongue is Swift 🦅
The first programming language I learned was Swift 1.0, and that was in 2014, before I learned C.
I would like to write any process in Swift, as long as the environment can run Swift. iOS / watchOS Apps, macOS / Linux CLI Tools, and more!

I'm working on TRETNFCKit (TRETJapanNFCReader before the name change), which wraps the Core NFC Framework for iOS. It's open source software!

A world where NFC is conveniently used is full of hope! Thank you for your support of my open source activities.
