What is the Swift equivalent of -[NSObject description]?

Question

In Objective-C, one can add a description method to their class to aid in debugging:

@implementation MyClass
- (NSString *)description
{
    ret         


        

Answer 1

Just use CustomStringConvertible and var description: String { return "Some string" }

works in Xcode 7.0 beta

class MyClass: CustomStringConvertible {
  var string: String?


  var description: String {
     //return "MyClass \(string)"
     return "\(self.dynamicType)"
  }
}

var myClass = MyClass()  // this line outputs MyClass nil

// and of course 
print("\(myClass)")

// Use this newer versions of Xcode
var description: String {
    //return "MyClass \(string)"
    return "\(type(of: self))"
}
