Share Extension Iterations

Daniel Jalkut:

The problem with all the targets on your Mac or iOS that may or may not support sharing pertinent data to your extension, is you have to walk them through the process of invoking you. When you’re deep into the development of a particular aspect of the user interface or mechanical behavior of your extension, what you really want is to repeatedly invoke the extension with the same, predictable kinds of data. Luckily, it’s possible on both Mac and iOS platforms for a host app to invoke sharing extensions programmatically, so you just need to choose a Run target that will predictably invoke your extension upon launching.

If you’re working on a Mac-based Share extension, the key to invoking it at runtime is to enlist the help of the NSSharingService infrastructure. You simply ask it for a service with your identifier, and ask it to “perform.”
