Declaring Global Variables in Swift

Question

I want to make a global array of custom objects that can be accessed throughout the app (AppDelegate, ViewController classes, TableViewController classes, etc). I have resea

Answer 1

Try making a new Swift file with this:

struct Constants {

  static let appName: String = "My App"

  struct Colors {

    static let colorTextStandard = UIColor(red: 0/255, green: 0/255, blue: 0/255, alpha: 0.3) //#000000

  }

  struct Data {

    static var myStrings = [String]()  // Yea, this is not a constant, but that's alright...

  }

}

You can then refer to those global constants (or you can make them variables) using:

Constants.appName

or

Constants.Colors.colorTextStandard

or

Constants.Data.myStrings = [stringOne, stringTwo]
