Initializing vs. Creating an object

Hi Treehouse!

I'd like to know why it's important to implement the init method when creating instances of structs/classes. How is it different from creating objects directly by passing in arguments?

let someObject = someStruct(<arguments>)

vs

let someObject = someStruct.init(<arguments>)

Don't these achieve the same thing? Please help clear this up!

To my knowledge, these are exactly the same thing. I think someStruct(<arguments>) calls someStruct.init(<arguments>). Creating an object, in this context, is the same thing as initializing it.

Thanks for the response! I'm confused as to why we need the init method though...
