Xcode Mac Autofill Not Working Properly

Below is my 2 files for this script. When I type a method included in the UE4 libraries, It can only autofill methods I’ve typed before and basic Xcode functions. What’s wrong?

its a know bug. the devs have been saying that its high on their list for the past while. so it might be fixed soon. but that is normal for Xcode as far as i know. (also if you google ue4 Xcode autocomplete the first post tells you to run a serise of console commands to fix it DO NOT DO IT i learned the hard way and had to completley delete ue4 and reinstall) but it will be implemented eventually.

Xcode 9 seems very buggy in conjunction with UE4 4.18. Autocomplete doesn’t work, Quick Help doesn’t work half the time, and no inline errors are ever displayed at all.
