How to install Xcode source editor extension?
<p>I created a source editor extension but don't understand how to use it. It works fine in debugging version of Xcode (with gray icon) but I cannot find a way to install this extension to "real" Xcode. Documentation is quite obscure for this topic. What I have tried - 1. Build and run host application. 2. Move resulting .appex file into PlugIns directory of Xcode. Nothing worked for me.</p>

<p>I use macOS Sierra and Xcode 8.</p>
