ScrollView {
Grid(colors) {
Rectangle()
.foregroundColor($0)
}
}
.gridStyle(
ModularGridStyle(columns: .min(100), rows: .fixed(100))
)
ScrollView {
Grid(1...69, id: \.self) { index in
Image("\(index)")
.resizable()
.scaledToFit()
}
}
.gridStyle(
StaggeredGridStyle(.horizontal, tracks: 8, spacing: 4)
)Tracks setting allows you to customize grid behaviour to your specific use-case. Both Modular and Staggered grid use tracks value to calculate layout. In Modular layout both columns and rows are tracks.
public enum Tracks: Hashable {
case count(Int)
case fixed(CGFloat)
case min(CGFloat)
}Grid is split into equal fractions of size provided by a parent view.
ModularGridStyle(columns: 3, rows: 3)
StaggeredGridStyle(tracks: 8)Item size is fixed to a specific width or height.
ModularGridStyle(columns: .fixed(100), rows: .fixed(100))
StaggeredGridStyle(tracks: .fixed(100))Autolayout respecting a min item width or height.
ModularGridStyle(columns: .min(100), rows: .fixed(100))
StaggeredGridStyle(tracks: .min(100))Get item size and position with preferences
struct CardsView: View {
@State var selection: Int = 0
var body: some View {
ScrollView {
Grid(0..<100) { number in
Card(title: "\(number)")
.onTapGesture {
self.selection = number
}
}
.padding()
.overlayPreferenceValue(GridItemBoundsPreferencesKey.self) { preferences in
RoundedRectangle(cornerRadius: 16)
.strokeBorder(lineWidth: 4)
.foregroundColor(.white)
.frame(
width: preferences[self.selection].width,
height: preferences[self.selection].height
)
.position(
x: preferences[self.selection].midX,
y: preferences[self.selection].midY
)
.animation(.linear)
}
}
}
