I'm using SwiftUI to create my app, and I want to use "if" statement to conditionally add a View to a VStack, but the following code fails to compile in my project:struct BookItemGroupVertical: View {
// BudgetBook is a custom class
var items: [BudgetBook]
private var halfNumber: Int {
return Int(items.count / 2)
}
var body: some View {
VStack(alignment: .leading) {
ForEach(0 ..< self.halfNumber) { index in
// BookItemGroupHorizontal is a custom View
BookItemGroupHorizontal(items: [self.items[index * 2], self.items[index * 2 + 1]])
}
// This is where the problem happens
if items.count % 2 == 1 {
Text("it")
}
}
}
}However, I've tried a simpler sample and it works:struct ConditionalTestView: View {
var array = [1, 2, 3, 4, 5]
var body: some View {
VStack {
ForEach(0 ..< 5) { _ in
Text("Something")
}
if array.count % 2 == 1 {
Text("Second Line")
}
}
}
}I'm wondering whether this is a bug of SwiftUI. If not, how can I solve this problem?Thanks.
