I can't seen a tree with quick look in Xcode

[macabeus]

Hello,

very interesting your project and code =]
I found your project while I was search about quick look.

In your blog post and code you wrote some functions to use quick look in Swift without annotation @objc. I thought interesting, because I need its, because we can't use @objc in struct's functions.

Then, I tested your project, but, the quick look not work as I expected:

Since TreeNodeEnum subscriber the protocol QuickLookableBinaryTree, I expected that I could seen the tree with quick look in Xcode.

I made some thing wrong?

Thanks for listening õ/
