structure vs class in swift language

Posted 2020-11-18 feng9exe

Both class and structure can do:

• Define properties to store values
• Define methods to provide functionality
• Be extended
• Conform to protocols
• Define intialisers
• Define Subscripts to provide access to their variables

Only class can do:

• Inheritance
• Type casting
• Define deinitialisers
• Allow reference counting for multiple references.

 

Major differences between Structures and Classes:

• Structures cannot Inherit from other types.
• Classes use type-casting to treat a class as a superclass or subclass, as well as check protocol adoption. Structs can only use the protocol adoption part.
• Structures do not have deinitializers.
• Structures cannot have multiple references to the same instance
