assign and copy properties

Property with ’retain (or strong)’ attribute must be of object type

so, declare a property as assign if it has a primitive value 
@property (nonatomic, assign) int someNumber;

You also use assign for structs, because they aren’t objects either 
@property (nonatomic, assign) CLLocationCoordinate2D coordinate;

Everyone on Stack Overflow does HTTP Basic Authentication on iOS by manually 
building the HTTP headers.

This amounts to re-implementing HTTP.

Why? The Cocoa Touch URL Loading System aleady knows HTTP, and you can
configure your URLSession to supply HTTP Basic Authentication credentials
like so.
