Go to the Apple Design Resources page and download the template for the OS you will be building for.Kindly enough Apple offers us UI templates and widget for Photoshop (as well as constantly updated for Sketch) through their Apple Design Resources page. However it isn’t quite as targeted toward application development as Sketch so it isn’t geared as much towards that purpose. Photoshop has been a well established graphics editor for over two decades. Obviously, each time an edit needs to be made, Sketch will need to be accessed and the multiple files will need to be updated in the repo. Sketch offers a very simple way to export the set of graphics. From there you can drag the files into your Asset catalog App Icon slots. If you go to that folder, you should see all your icon sizes.

In the Export dialog, select all the sizes you wish to export and then choose the folder you wish to export to. When completed, go to the top menu and select Export.As you edit the large icon, you changes should be reflected in your other app icon sizes. Now, you should see the template with various sizes of the app icon. Run your Sketch Application and the launching dialog should appear showing various templates built into Sketch.Luckily they already supply an app icon template to use. In the last few years, Sketch has grown to be one of the leading applications used by graphic designers especially in the area of mobile application development.
