Courses Plus Student 2,669 PointsHi, id thing = nil; NSNumber *thing=4;
Since you have already defined thing as a type id, you are redefining thing in the next line. I hope the code below will help.
NSNumber *thing=@4; //define things a NSNumber type and the assign it the value 4 by using the @ literal.
