Struct

• Value type
• Copied when passed or assigned
• Copy on write
• Functional programming
• No inheritance
• “Free” init initializes ALL vars
• Mutability must be explicitly stated
• Your “go-to” data structure

Class

• Reference type
• Passed around via pointers
• Automatically reference counted
• Object-oriented programming
• Inheritance (single)
• “Free” init initializes NO vars
• Always mutable
• Used in specific circumstances
• The ViewModel in MVVM is always a class

I’m working on creating a Udemy and Skillshare about SwiftUI development. Hit the comment below if interested when it goes live.
