Because the concept of a new namespace in Swift (where files in the same namespace can be accessed directly without introducing a header file), creating a controller with a string requires a namespace

1 First, write a classification for the bundle to get the namespace

extension bundle{    varnamespace  : String {     return   Infodictionary? ["cfbundlename"as""    }}

2 The controller is then created directly from the string

Guard Let Class = nsclassfromstring (bundle.main.namespace+ ".") + "Your controller name string") as? Uiviewcontroller.type else {                    } let VC = Class.init ()
