Excited to announce that I completed the last module for my multi-Target Swift/SwiftUI app. I nailed synchronization among Mac, iOS and WatchOS using NSUbiquitousKeyValueStore and AppGroups for Widgets. Release date is this Sunday. Just about to send out coupon codes to my monthly Ko-fi subscribers

The Reluctant Traveller Season 3 finale on Apple TV is basically a love letter to my hometown, Vancouver. The market I still bike to, the mountain just 15 min away that I still ski, the bars I used to close down. It’s my city in every frame. Makes me proud to call this place home.
