I am using SwiftUI and pulling JSON from an Online API. I have decoded the item and now struggling trying to display only 6 of the items at random. The 6 items will display once a button has been clicked but I have not created the button yet. Any Ideas on how to display 6 items at random?
import SwiftUI
import SDWebImageSwiftUI
struct TestPost: View {
@ObservedObject var getData = ListData()
var body: some View {
NavigationView {
VStack {
// Not Working...
// Displaying Json Data, I want to display 6 at random when view appears.
ForEach(getData.jsonData.indices, id: \.self) { item in
if item < 6 {
ListRow(firstName: item.firstName)
}
}
//Working... Able to Display Names
List(getData.jsonData) { item in
ListRow(firstName: item.firstName)
}
}
}
}
}
Updated Code. I figured out how to get the 6 items and will be working on how to do it at random.
import SwiftUI
import SDWebImageSwiftUI
struct TestPost: View {
@ObservedObject var getData = ListData()
var body: some View {
NavigationView {
VStack {
// Not Working...
// Displaying Json Data, I want to display 6 at random when view appears.
ForEach(getData.jsonData.indices, id: \.self) { item in
if item < 6 {
ListRow(firstName: self.getData.jsonData[item].firstName) //Updated Code...
}
}
//Working... Able to Display Names
List(getData.jsonData) { item in
ListRow(firstName: item.firstName)
}
}
}
}
}
