Dumps all the NSObject inherited classes in the process. If you give it a module,

Example:
# Dump ALL the NSObject classes within the process
(lldb) dclass
# Dump all the classes that are a UIViewController within the process
(lldb) dclass -f UIViewController
# Dump all the classes with the regex case insensitive search "viewcontroller" in the class name
(lldb) dclass -r (?i)viewCoNtrolLer
# Dump all the classes within the UIKit module
(lldb) dclass -m UIKit
# Dump all classes in CKConfettiEffect NSBundle that are UIView subclasses
(lldb) dclass /System/Library/Messages/iMessageEffects/CKConfettiEffect.bundle/CKConfettiEffect -f UIView
# Generate a header file for the class specified:
(lldb) dclass -g UIView
# Generate a protocol that you can cast an object to. Ideal when working with private classes at dev time
