-
Immutable View
- SwiftUI View is immutable
- Entire UI is constantly rebuilt
- If you want to change a variable in a View use @State
- @State points to a memory
- if the value changes in a memory, the View will get rebuilt
-
Identifiable
- Identifiable just has a hashable id
- ForEach's contents should be identifiable
- To adjust the Views from changes
-
LazyVGrid
- LazyGrid creates items only as needed
- "lazy" doesn't create items until it needs to render them onscreen
-
Stroke
- Stroke draws line on top of the border
- Some of the line is spilling onto the inside and the outside
- To ensure all the borders put inside of the boundaries, use
strokeBorder()
