init(columns: [GridItem ], alignment: HorizontalAlignment , spacing: CGFloat?, pinnedViews : PinnedScrollableViews , content: () -> Content)Creates a grid that grows vertically, given the provided properties.
Overview 概要
The grid is “lazy,” in that the grid view does not create items until they are needed.
In the following example, a Scroll contains a Lazy consisting of a two-column grid of Text views, showing Unicode code points from the “Smileys” group and their corresponding emoji:
var columns: [GridItem] =
Array(repeating: .init(.flexible()), count: 2)
ScrollView {
LazyVGrid(columns: columns) {
ForEach((0...79), id: \.self) {
let codepoint = $0 + 0x1f600
let codepointString = String(format: "%02X", codepoint)
Text("\(codepointString)")
let emoji = String(Character(UnicodeScalar(codepoint)!))
Text("\(emoji)")
}
}.font(.largeTitle)
}
