Problem displaying Button

[NGLocanovic]

Hello and first of all thanks for sharing this awesome ColorPicker.

But there ist one problem I'm currently facing.
When I'm adding another object (like: button, slider, uiView ...) into the scene, it won't display at runtime nor in xCode 6 new Debug Screen.

I don't now the Problem. Maybe You?

I'm trying to replicate your probrem. but, it works.

Please check your constraints. you should add constraints to your button.

Hmm, I checked all my constraints. The Button is shown correctly in Storyboard's Preview Mode:

Maybe I can send your my project and you could check it? That would be great :)
