Can build successfully once I remove the target 'XLPagerTabStrip' manually from TwitterPagerTabStripViewController.swift

On device this is not necessary.

For me it's only a problem on iphone 5 simulator. Wonder if it has anything to do with 32 vs 64 bit architecture.

The error is caused in TwitterPagerTabStripViewController.swift lines 116, 117
let oldRect = (change![NSKeyValueChangeKey.oldKey]! as AnyObject).cgRectValue
let newRect = (change![NSKeyValueChangeKey.oldKey]! as AnyObject).cgRectValue
specifically .cgRectValue is causing the error.

But as you can see this code is not doing much because both variables are assigned the old value so the next line:
if (oldRect?.equalTo(newRect!))! {
is always being true.
