Key design principles
Main Question: what is the most relevant information of my app?
Example new weather app
Watch experience should be optimised on brief interaction
Digital crown interactions should be always backed up by touch interaction
Which information would be the core for a widget of my app
Build app around this foundation
Navigation
NavigationSplitView
Concept borrowed by two column layout
Perfect if app has source list
App should open directly in detail
Transition between source list and detail view
API similar to other plattforms
TabView
Example: Activity app
Animations based on election view
matchedGeometryEffect for merging and animating content between tabs
NavigationStack
Lead people into and back from hierarchical structure
Layout
Flexibel Grid
3 foundational layouts
List
Scroll though content
Dail
Dense information delivered at one glance
Infograhic
Ideal for data visualisation
Topbar Leading and Topbar Trailing Placement
Time moves to center
More control on screen by using less interaction time
Color and materials
Should give sense of view hierarchy
Four background materials
Ultra Thin, Thin, regular, thick
Use color to differentiate similar views
Convey state change with color
Vibrant versions of all system colors
Example: Noise App
NavigationBar with blur
