I have just designed an icon in Sketch for a Watch app. In Xcode, it looks like I need to create 11 different sizes of this icon. What is the quickest way to do this? Is there an app/script that can import the icon I've created and creates the 11 different-sized icons? Thanks.
Take care, I did not test.
But this app seems designed for that : h ttps://appicon.co
Visit the Mac App Store and see what they offer in the way of icon and screenshot makers that fits your budget and needs. Otherwise, I know not of a simple script that will cough up everything you need in the proper size/format.
