Xcode 5 debugger no objective-c description available

In Xcode 4, when I use the debugger to print an NSArray count, it would show in the console like this:

po [self.array count]
3

In Xcode 5, doing this gives me

[no Objective-C description available]

This seems to be the case with all numerical types. What is the change or reasoning behind this behavior?

The command po stands for "Print Object". self.array.count is type NSUInteger which is not an object. Use the p command instead, which is intended to print non object values. E.g.

p self.array.count

The LLDB docs are a great resource.

In the meantime, I found that if you enclose any numerical type into an NSNumber, it would print out in the console like this:

int index = 1;

po index
[no Objective-C description available]
po @(index)
1

po @([self.array count])
3
