🔴 主題

• Grid - ⭐️ iOS 16 feature.

• grid layout algorithm

• GridItem

  • flexible column

  • adaptive column

⭐️ 重點

To make grids scrollable, they must be wrapped inside a ScrollView with the appropriate axis. 👉 SwiftUI Lab

the minimum property of an adaptive column is only used to compute the number of items inside that column, it's NOT the minimum width of that column❗️ ( 👉 Adaptive Column 💈例二 )
