How to left align masterdetail icon on ios?

The hamburgermenu icon is center aligned on ios, but on android it works fine and is left aligned.

Master.xaml

    <ContentPage xmlns=""
                 xmlns:x=""
                 x:Class="Name.Master"
                 Title="Master"             
                 Icon="Hamburger_icon_sm.png"                     
                 >

InitialPage.xaml.cs

    namespace Name
    {
        public partial class InitialPage : MasterDetailPage
        {
            public InitialPage()
            {                    
                InitializeComponent();
                this.Master = new Master();
                var detail = new Detail();
                this.Detail = new NavigationPage(detail) {        

                    BarTextColor = Color.White

                }; 
                App.MasterDetail = this;            
            }
        }
    }

How can I make it left aligned on ios also?
