Class name to string in Swift

gistfile1.swift

class Person {
    class func classString() -> String {
        return NSStringFromClass(self)
    }
}


Person.classString() // "_TtC11lldb_expr_06Person"

import UIKit


protocol TypeName: AnyObject {
    static var typeName: String { get }
}

// Swift Objects
extension TypeName {
    static var typeName: String {
        let type = String(describing: self)
        return type
    }
}

// Bridge to Obj-C
extension NSObject: TypeName {
    class var typeName: String {
        let type = String(describing: self)
        return type
    }
}


class MyViewController: UIViewController { }

class SwiftClass: TypeName { }
class MySwiftClass: SwiftClass { }


print(MyViewController.typeName)    // print "MyViewController" 

print(UIViewController.typeName)    // print "UIViewController"

let myVC = MyViewController()
print(type(of: myVC).typeName)    // print "MyViewController"

let VC = UIViewController()
print(type(of: VC).typeName)    // print "UIViewController"

print(String.typeName)
// print "NSString"
// cause: extension NSObject: TypeName
// String === NSString(Bridge)

print(SwiftClass.typeName)    // print "SwiftClass"

print(MySwiftClass.typeName)    // print "MySwiftClass"

nice.
