It seems the behavior of LazyVGrid has changed a bit in Xcode 13. For my use case, I need a grid with each item's height being variable. Here is the implementation: struct ExampleLazyVGrid: View {     private let columns = Array(repeating: GridItem(.flexible(), spacing: 24), count: 4)     private let sizes: [CGFloat] = [100, 150, 80, 110, 50, 120, 90, 40, 130, 140, 70, 60]     var body: some View {       LazyVGrid(columns: columns, alignment: .leading, spacing: 24) {         ForEach(sizes, id: \.self) { size in           VStack(spacing: 0) {             Rectangle()               .fill(Color.gray)               .frame(width: size, height: size)             Spacer()           }         }       }       .background(Color.gray.opacity(0.5))     }   } In Xcode 12.5, the rectangles are aligned at the top as expected as shown here: In Xcode 13, the Spacer() is ignored and the rectangles are no longer top aligned as shown here: So same code, just different behavior between Xcode 12.5 and Xcode 13. I'm experimenting with a workaround, but seems like a bug to me?
