<div>
<pre>1. Source
@interface Person : NSObject
@end
@interface Person ()
{
NSString *firstName;
}
@end
@implementation Person
{
NSString *firstName;
}
2. Expected behavior
I expect an error as the ivar would be defined in the class' interface:
"Error: Instance variable is already declared"
3. Actual behavior:
No error, but two ivars with the same name.
Thanks in advance</pre>
