How to get the most from protocol extensions - Swift for Complete Beginners

[@MarianoTufro]

This video is epic, and the fact that I could follow it with a cold is a testament to how clear you are. Thanks a lot! Protocols and extensions are fascinating. I never liked multiple inheritance.

please more like this. Its so much fun to simplify code after watching your Ideas

You right Paul - I am studying Swift “just for fun” and when I don’t understand something I push myself to study further saying myself “You will understand later on”))

Hello,
struct AAA: Equatable {
}
Why is not necassary to implement the static func == ? If you look in the Swift Documentationthe static func is REQUIRED.

[@twostraws]

Swift is able to create one for us automatically, as long as everything inside the struct already conforms to Equatable.

[@LebenWerden]

@@twostraws But inside is nothing?How can nothing conforms to Equatable?

[@twostraws]

Because two objects with nothing to make them different are automatically considered equal.

extension Numeric {
func square() -> some Equatable {
self * self
}
}
The above seems to make the extension more flexible as well...🤷🏿‍♂️

It IS confusing, but VERY curious part of me wants to know more about the extension

I am a beginner bot I find Protocols and Extensions much more easier than Closures)
