Answer / Shiv Dutt Dayal
In Swift for iOS development, 'Strong' and 'Weak' are reference attributes. A variable with a strong reference means that the system will retain the object it points to until the variable goes out of scope or is set to nil. Weak references do not keep an object alive; if the object has no other strong references, it may be deallocated at any time.
