Get binary ttf font file data using iOS API?

How do I get binary ttf font file data in my app using iOS API?


I know that there are font directories such as "/System/Library/Fonts" with font files in it but an Apple employee said that we should not load ttf data from there and instead use CoreText (See Apple's video "Introducing the New System Fonts" https://developer.apple.com/videos/play/wwdc2015-804/ minute 29:25). But how does this work?
