Understanding Objective-C’s Weak Reference to an Object in Arrays Introduction In Objective-C, when you add an object to an array, the compiler automatically creates a strong reference to that object. This means that as long as the array exists, the object will remain alive and will not be deallocated until all references to it are gone. However, sometimes we want to store only the reference to an object in an array without creating multiple copies of the object.
