lldb throwing error: use of undeclared identifier 'NSMakeRange'

Question

If I pause an app's execution and try this command in the debugger: po NSMakeRange(0, 1) I receive the error:

error: use of undeclared identifier 'NSMakeRange'
error: 1 errors parsing expression

I tried using expr @import Foundation to no avail.

Use the next create NSRange variable:

e NSRange $range = {.location = 2, .length = 1}
po range

But as explained here iOS, "NSRange is just a forward declaration and I do not know the real symbol for the implementation". That is why you may have issues with using this range variable in the debugger.

Use `po $range` to get the variable. – John Doe May 05 '19 at 10:05
