Can I have a default memberwise initializer for a class in Swift?

Question

Let’s say I have a class Foo:

class Foo {
   let bar: String
   let baz: String
}

Do I really have to write the memberwise initializer by hand?

init(bar: String, baz: String) {
    self.bar = bar
    self.baz = baz
}

It’s pure boilerplate.

Answer 1

If you can work with value semantics instead of reference semantics, you can use a Struct instead of a Class, they have automatic memberwise initializers.

If not, then you have to provide the full init yourself for your class.
