Collecting reference UIs, designing an interface with pen and paper, experimenting with SwiftUI and AWDL. Created a bunch of reference UIs (mostly recreating the apple stock app onboarding screen) and experimented with modifiers and styling on them. Also did 3 iterations of the AWDL & BLE networking stack and its status representation in the UI. Watched a lot of Apple design keynotes and read the Human Interface Guidelines (highly recommend!). Mocking up the home screen and onboarding UIs with pen and paper was a bunch of fun, I haven’t done that in a long time!
