How to create a proper singleton for Dictionary in Swift 2

I have the following code

class Test: UIViewController {
  var imagesOfChef = [Int : chefImages]()
    struct chefImages {
          var objidChef: String!
          var imageChef: UIImage!
      }

}

I fill up this dictionary as soon as the user opens the application. But i want it to be available also in other Views (swift files)

Lets say in this class

class Test2: UIViewController{

}

How can i create a singleton for this Dictionary so it can be available to other views?

Thanks for your time!

Solution

  • You can use a static property:

    static var imagesOfChef = [Int : chefImages]()

    and then you use:

    Test.imagesOfChef

    But I suggest avoiding the static approaches as much as possible, you can use the prepare segue or assign the property from outside if possible if Test has Test2.
