Fuzzy Autocomplete for Xcode

Not compatible with Xcode 9

Xcode 9 beta has this functionality built in now!

FuzzyAutocomplete 2.1

This is a Xcode 5+ plugin that patches the autocomplete filter to work the same way the Open Quickly works. It performs very well, and the fuzzy matching actually uses Xcode's own IDEOpenQuicklyPattern.

Authors

FuzzyAutocomplete is brought to you by:

• Leszek Ślażyński (@slazyk) - author of the 2.x version
• Jack Chen (@chendo) - original creator of the 1.x version

See @chendo's original blog post about how he figured out what to patch: Reverse engineering Xcode with dtrace
