I have a static method in Swift
class BaseAsyncTask: WebServiceClient { class func execute(content : [String:AnyObject], cancelled:CustomBool) { // Print class name (BaseAsyncTask) here } } And I want to know how to get the class name inside that method. I tried
self.dynamicType but that gives error (I suppose because of the self inside a class function)
There are different methods to do that, if your method inherits from NSObject you can expose it to objective-c and do something like that.
@objc(BaseAsyncTask) class BaseAsyncTask: WebServiceClient { class func execute(content : [String:AnyObject], cancelled:CustomBool) { println("Class \(NSStringFromClass(self))") } } For pure SWIFT introspection check here about MirrorType
I've found also this extension credits to ImpactZero
public extension NSObject{ public class var nameOfClass: String{ return NSStringFromClass(self).components(separatedBy: ".").last! } public var nameOfClass: String{ return NSStringFromClass(type(of: self)).components(separatedBy: ".").last! } } [Xcode 8]
Alex suggested me that in the Xcode 8 version this code shows a warning. To avoid that we should prefix the method like that:
@nonobjc class var className: String{ return NSStringFromClass(self).components(separatedBy: ".").last! } 
@nonobjc attribute before public class var nameOfClass to avoid the following warning (Xcode 8.2): "ld: warning: Some object files have incompatible Objective-C category definitions. Some category metadata may be lost. All files containing Objective-C categories should be built using the same compiler." Like so: @nonobjc class var className: String{ return NSStringFromClass(self).components(separatedBy: ".").last! }You can use string interpolation to print self:
let className = "\(self)" Sample code:
class BaseAsyncTask: WebServiceClient { class func execute(content : [String:AnyObject], cancelled: CustomBool) { let className = "\(self)" print(className) } } class AnotherAsyncTask : BaseAsyncTask { } BaseAsyncTask.execute([:], cancelled: true) // prints "BaseAsyncTask" AnotherAsyncTask.execute([:], cancelled: true) // prints "AnotherAsyncTask" 
Another way to do this, when you don't have an instance of the class is this.
Swift 4
print(String(describing:BaseAsyncTask.self)) Swift 2
print(String(BaseAsyncTask)) Inspired here.
String(describing:BaseAsyncTask.self)
