Seg fault compiling for the first time

[kuyawa]

Hey guys, I love this project so I cloned it, opened it in Xcode and started compiling just to get a segfault error in MultiDictionary.swift:

Showing Recent Messages
Command failed due to signal: Segmentation fault: 11

CompileSwift normal x86_64 /Volumes/Documents/mini/Sites/Swift/Embassy/Embassy/MultiDictionary.swift

Let me know what I need to do in order to make it run, can't wait to test it.

@kuyawa are you using the latest Xcode, 8.2.1?

[kuyawa]

Nop, Xcode 8 and Swift 3. Will update and try again, thanks.
