//Example of turning structs into Createable & Updateable

struct SomeStruct: CreateableDefault {
    var someInt = 12
    var someString = "asdf"
}

let a = SomeStruct.create {
    $0.someInt = 10
    $0.someString = "abcd"
}!

a.update {

//Example of defining how to create UIViewController out from storyboard:

class SomeVC: UIViewController, Createable {
    var someInputParam: SomeStruct!
    static func create() -> Any? {
        let storyboard = UIStoryboard(name: "SomeStoryboard", bundle: Bundle.main)
        return storyboard.instantiateViewController(withIdentifier: "SomeVC")
    }
}

SomeVC.create {
    $0.someInputParam = SomeStruct.create {
        $0.someInt = 9000
        $0.someString = "You get the idea"
    }
