Unlike AppCode, Xcode doesn’t allow you to associate a custom file extension with a color scheme. When using Vapor and Leaf, this means you have to go to
Editor > Syntax Coloring and select
HTML every time you open a .leaf file. This is annoying and to make things worse Xcode doesn’t remember this setting after you (re)build the project 😡
To fix this annoyance, I’ve made a very tiny MacOS app that automatically associates .leaf to .html file for you. All you have to download this tiny app, and double-click it. You can then close the app. No further action required! You can now open your .leaf file and Xcode will recognize it as an HTML file and automatically sets syntax coloring for you.
