Global Variable in Swift

Question

I'm creating an iOS 8 app and I want to create a string variable that is accessible to all class. I tried to create global.swift with a string variable in it. I can access the variable but, everytime I initialize the class again using this line let globalVar = global() the value that I've passed returns a nil value. Can someone help me with this. Thank you.

You can put the variable in your AppDelegate, which is a singleton. See this post for how to access the AppDelegate

Put

public static var global = "String"

in any class. Access via Classname.global.

Just use your Global.swift file and put your global variables and functions inside without any class around it.

//
//  Global.swift
// 

let myConstant = 5

func myGlobalFunction() {
    // ...
}

You can access those variables and functions all around your module.
