lldb error: property not found on object of type

I had to disable (uncheck) Thread Sanitizer in Xcode > Product > Scheme > Edit Scheme > Run > Diagnostics. With Thread Sanitizer enabled I wasn't able to access many NSView properties (e.g. bounds, frame) through LLDB.

Dot notation for message sending is not supported in lldb when using Objective-C. Use bracket notation and cast the result to CGRect:

p (CGRect)[view frame]

Just in case the above doesn't work (which it didn't for me, looking for the frame for a variable cell, class derived from UITableViewCell): forcing the extra parentheses seemed to help lldb's little ditty brain:

p ((CGRect)[cell frame])

presto magico:

(CGRect) $5 = origin=(x=0, y=0) size=(width=320, height=44)
