Swift reflection Mechanism, namespace

1. Know that there is a namespace in Swift
-Share globally under the same namespace!
-third-party framework using Swift if you drag directly into the project, dependent on the same namespace, there is a good chance of conflict!
-Try to use cocoapod later
2, the focus is to know how Swift nsclassfromstring (launch mechanism) of the wording
-The most important purpose of the launch is decoupling
-Tip: First impressions will find a simple function that is very complex to write. But the package is good, the elasticity is very big!

In a program, you need a namespace when you need to use string to get the class name

Let Clsname = Bundle.main.infoDictionary? ["cfbundlename"as"" ". " " Viewcontroller "  as? Uiviewcontroller.type

So that we can get the right Viewcontroller .
