Cant find LLVM6.0 in build settings to add .pch prefix header

Question

I created a new project using Xcode 6.3.1 and I want to manual add a 'pch' file to my project. I was looking at questions online PCH File in Xcode 6 but the selected answer says to go to LLVM6.0 but that does not exist in build settings anymore. Where can i find it to add the .pch?

You could always create a project with a `.pch` added automatically, then look for where it's used. — Lord Zsolt, Apr 23 '15 at 09:41

To create a prefix header (pch) file you'll have to do the following:

Go to (or use ⌘cmd+N) File > New > File > Other (in iOS or OSX).
Select PCH File.
Give it a name and store it somewhere in your project.
Go to your project's target > Build Settings.
Search for prefix header.
Under Apple LLVM 6.1 - Language you will find the Prefix Header key.
Add the path to your pch file like so: $(PROJECT_NAME)/myPrefixHeaderFile.pch.
Clean your project (⌘cmd+⇧shift+K) and build (⌘cmd+B).

Below is a screenshot showing where to find it in Build Settings: Prefix Header (PCH) File

Search for prefix header - Under Apple LLVM 6.1 - Language Set Precompile Prefix Header to Yes and then set Path of your .pch file in Prefix Header
