Warning
@abynim was kind enough to grant me access to the original Lippy source code, so I brought all those compatibility patches upstream. Which means, go download an official plugin instead – it works fine now; don't use this patch.
This is a runtime patch for Lippy.sketchplugin by @abynim that makes it fully compatible with the latest version of Sketch (v100 at the time of writing).
Instead of manually re-writing -[LippyMainViewController showEditorForContext:] and a few other methods to use proper Sketch APIs (which might have been easier in retrospect 🗿) this patch intercepts various -valueForKeyPath: calls made by the plugin on Sketch data models, and makes them return stuff in a format that Lippy expects. See LippyPatcher.m for details.
