Using a Variable Named "description" When Extending NSObject

I have a project with a class that extends NSObject:

interface ExtendedObject : NSObject<MKAnnotation>

@property NSString *name;
@property NSString *address;
@property NSString *description;

@end

When I later use this class and attempt to assign a value to the object's description variable:

#import “ExtendedObject”

@implementation MyClass

-(void)viewDidLoad {

    ExtendedObject *myObj = [ExtendedObject alloc];
    myObj.description = @“SOME TEXT HERE”;

}

@end

I get an error: -[ExtendedObject setDescription:]: unrecognized selector sent to instance

From what I have gathered, this is occurring because description is the name of a method of NSObject.

This was not causing a crash until I started testing on iOS 8.

Is my understanding correct and is there a way to use a variable named description here?

There is already a read-only description property in NSObject. Use a different name.
