What is the difference between weak and unowned?



What is the difference between weak and unowned?..

Answer / Varsha Choudhary

Weak references do not increase the retain count of the referenced object, and they are set to nil automatically when the referenced object is deallocated. Unowned references also do not increase the retain count but cannot be nil; this means that the referencing object must be assured to exist before using the unowned reference.
