error: property 'frame' not found on object of type 'UIView *'

If you hate typecasting every time, you can try this:

(lldb) expr @import UIKit(lldb) po self.view.bounds

Since Xcode 7.2 is now available, I think we should update the answer.
I find the answer here, Why can't LLDB print view.bounds?

ios view lldb

Try this

p (CGRect)[view frame]

Alternative to get the frame of the view:

po view

ios view lldb

Try this,

po view.layer.frame.size.height
