Auto Highlight Symbol

About Xcode 8

Xcode 8 does't support plugins anymore, but there is a workaround, use at your own risk.


Xcode can highlight instances of selected symbol, but what it does is to add dash lines under the instances, which is hard to be noticed.

AutoHighlightSymbol is a plugin for Xcode, it adds background highlight color to those instances. It's super useful while you're tracing codes, especially when you want to figure out where a specific variable is used in a certain method.

You're welcome to improve it and send me pull requests.
