Linker errors with ParseUI iOS and CocoaPods
I was trying to create an application using Parse and wanted to give ParseUI a shot. I imported the main Parse SDK using Cocoa pods and it worked fine. When I decided to add ParseUI I ran into problems.

I've tried using things like forcing Parse.framework to bind ParseUI, but it doesn't seem to help. I'm not an expert with cocoapods or with XCode, so I don't know if there is something obvious that I'm missing.
I've tried cocoapods 0.35 and 0.36-beta-1. This is a quick project, so I don't know if it might be causing some problems.

You need to use the Bolts.frameworks framework. This structure is part of the Parse SDK. Another thing is that with the latest version of the Parse SDK (v1.6.2 right now) you will have to import Parse / Parse.h, ParseUI / ParseUI.h, or both depending on which objects you are using. Tell me if you need more information about installing de Bolts framework! :)
