ios - Remove extra line separators below List in SwiftUI

I've created a simple List as below, but there are extra separators below it.

List {
  Text("Item 1")
  Text("Item 2")
  Text("Item 3")
}

Result:

enter image description here

I've tried embedding the List inside a VStack and adding Spacer() like below code but it's not working properly. It removes about half of the empty cells.

VStack{
  List {
    Text("Item 1")
    Text("Item 2")
    Text("Item 3")
  }
  Spacer()
}

How would I remove these extra separators in SwiftUI?

iOS 14:

iOS 14 doesn't show extra separators below the list by default and to removing all separators, you need to use a LazyVStack inside a ScrollView instead. (because iOS is NOT supporting appearance for SwiftUI lists anymore).

LazyVStack Preview


iOS 13:

?? This method is deprecated and it's not working from iOS 14

No need for Section or .grouped style!

There is a UITableView behind SwiftUI's List for iOS 13. So to remove

- Extra separators (below the list):

you need a tableFooterView and to remove. Note that iOS 14 doesn't show extra separators below the list by default.

- All separators (including the actual ones):

you need separatorStyle to be .none

init() {
    if #available(iOS 14.0, *) { 
        // iOS 14 doesn't have extra separators below the list by default.
    } else {
        // To remove only extra separators below the list:
        UITableView.appearance().tableFooterView = UIView()
    }

    // To remove all separators including the actual ones:
    UITableView.appearance().separatorStyle = .none
}

var body: some View {
    List {
        Text("Item 1")
        Text("Item 2")
        Text("Item 3")
    }
}

Note that it eliminates all tables/lists's separators. So you can toggle it in a methods like onAppear() or etc. as you wish.
