Actually Include it in iOS
One of the biggest things holding Apple Shortcuts back is the fact that not every user even knows it exists. While Apple made a big deal of Shortcuts when it debuted it at WWDC, there are likely quite a few users who didn’t see that announcement — and don’t know about Shortcuts at all.
Apple could do a better job getting the word out about Shortcuts, especially since it’s an incredibly useful tool even for the most casual of users. A simple place to start? Actually include Shortcuts as a native app when a user buys a new iPhone or downloads a new version of iOS. There’s no reason for Shortcuts to be hidden in the App Store.
