I add a template to my page 100 times. Is there a way that I could speed that up?

Here is the code that I have:

        details.Children.Add(new LineTemplate());

        foreach (var x in App.cardSetWithWordCount.Select((r, i) => new { Row = r, Index = i }))

        {

            if (x.Index != 0) details.Children.Add(new SeparatorTemplate());

            if (selected == true) x.Row.IsToggled = true;

            if (selected == false) x.Row.IsToggled = false;



            var cell = new SwitchGridTemplate

            {

                IsToggled = x.Row.IsToggled,

                BindingContext = x.Row,

                Text = x.Row.Name,

                Label = x.Row.TotalWordCount.ToString(),

                ToggledCommand = (Command)vm.SelectCardSetCmd,

                RowId = x.Row.Id

            };

            details.Children.Add(cell);

        }

It takes 8-9 seconds to run and I would like some advice on if there is a different way that I could be adding this that might be faster.

Note that details is a stacklayout on my page.
