How can I view an NSError?

What's the best way to log an NSError?

- (void)checkThing:(Thing *)thing withError:(NSError *)error {
    NSLog(@"Error: %@", error);
}

Gives me a null message

Solution 1:

Looking at the NSError documentation tells me that you'll need to do something like:

NSLog(@"%@",[error localizedDescription]);

This should then give you human readable output

NSLog(@"Error: %@", error);
Gives me a null message

Then error is nil, not an NSError instance.
