The default icon that SpriteBuilder provided us was convenient for testing but it's time we set ourselves apart and create our own icon.
Tip
To use the template we'll be talking about in the next section, you'll need Photoshop. If you have a design team, you likely have it somewhere. If you don't have Photoshop, you can get a free trial version from its website.
There are about 10 to 15 different app icon sizes, depending on which devices you plan to support and which iOS versions you're supporting. It would be a pain to manually update all of these sizes if you change your icon. Thankfully, it's easier than ever to create the required app icon sizes with a template that was created by Michael Flarup.
You can download the template from www.appicontemplate.com. Once it is downloaded, you can open it from Photoshop and begin using it. Once you're ready, you just have to run the action included in the download and it will generate the files for you.
