SOLVED: Protocols: Difference between "get" and "set"

Forums > SwiftUI

what is the difference between "get" and "set"? and when should we use these two?

1      

get is for when you return the value of a property.

set is for when you assign a value to a property.

A property that is described as { get } is a read-only property.

A property that is described as { set } is a write-only property.

A property that is described as { get set } is a read-write property.

is there any example of set only property? swift is forcing you to have getter with setter! so there cant be a setter without a getter even if getter returns nothing it still should be there.

Nah, rereading the docs I guess it's not allowed. That's what I get for answering questions in bed immediately after waking up.
