A breakpoint I cannot live without
I'm often working on projects from other devs. Some of the projects are quite complicated and I have difficulties to remember all the view controllers. Here is a breakpoint that helps me a lot when figuring out what's going on and where I need to fix a bug.
The breakpoint prints the class name of the current view controller to the console. It's a symbolic breakpoint on
-[UIViewController viewDidAppear:] with the debugger command
To have the breakpoint in all projects, move it to the User. This can be done by Crl click on the breakpoint and selecting Move Breakpoint To / User.
