“initialize” class method for classes in Swift?

Question

I\'m looking for behavior similar to Objective-C\'s +(void)initialize class method, in that the method is called once when the class is initialized, and never a

You can use stored type properties instead of initialize method.

class SomeClass: {
  private static let initializer: Void = {
    //some initialization
  }()
}

But since stored types properties are actually lazily initialized on their first access, you will need refer them somewhere. You can do this with ordinary stored property:

class SomeClass: {
  private static let initializer: Void = {
    //some initialization
  }()
  private let initializer: Void = SomeClass.initializer
}
