Elegant way to show an array list of int - ios

Question

Hi everyone I am working with a LazyVGrid on my SwiftUI project for displaying a list of times ...
This is the array of hours
let hoursList = [09, 10, 10, 11, 11, 12, 12, 13, 14, 14, 15, 15, 16, 16, 17, 17, 18, 18]
let columns = Array(repeating: GridItem(), count: 4)
LazyVGrid(columns: columns, alignment: .center, spacing: 10) {
ForEach(viewModel.hoursList) { hours in
Text("\(hours)")
}
///////////
// more elegant way to get the times as in the array?
//////////
}
As you can see in the array there are times that repeat for example 10 - 10, 11 - 11
Is there a more elegant way to get an array like the one above but without specifying every number? instead of directly using 'hourList' can I reach my goal using a more elegant way?

Answer 1

Hour & Minute should Convert into Number System, so
HH:mm from Clock will be (HH).(mm/60) in Numeral
02:00 is 2.0
06:30 is 6.5
08:45 is 8.75
15:55 is 15.916666...
extension Double {
var minute: Int { Int(self * 60) - Int(self)*60 }
}
let hoursList = [9.5, 10.0, 10.5, 12, 12.5, 14.5, 15, 16, 17, 17.75, 18, 18.25]
let columns = Array(repeating: GridItem(), count: 4)
LazyVGrid(columns: columns, alignment: .center, spacing: 10) {
ForEach(viewModel.hoursList) { hour in
Text(String(format: "%d : %.2d", Int(hour), hour.minute))
}
}
