How to create struct data globally accessible in a singleton class in swift 2.0 (iOS)?

Question

I\'m very new to iOS programming and swift. I am trying to create a singleton class to store my global data. My global data are a struct and an array of this struct. I want

Unless there's a very specific reason to do it, you don't need to nest classes like that.

Let's simplify a bit your code for the exercise:

struct Info {
    // No need for these properties to be Implicitly Unwrapped Optionals since you initialize all of them
    var firstname: String
    var lastname: String
    var status: String

    init (firstname:String, lastname:String, status:String) {
        self.firstname=firstname
        self.lastname=lastname
        self.status=status
    }
}

class Global {

    // Now Global.sharedGlobal is your singleton, no need to use nested or other classes
    static let sharedGlobal = Global()

    var testString: String="Test" //for debugging

    var member:[Info] = []

}


// Use the singleton like this
let singleton = Global.sharedGlobal

// Let's create an instance of the info struct
let infoJane = Info(firstname: "Jane", lastname: "Doe", status: "some status")

// Add the struct instance to your array in the singleton
singleton.member.append(infoJane)

Now it would make sense to me. A struct holding info about some user, and I can make any number instances of them - and a singleton class, unique, were I can store these Info instances, this singleton being usable anywhere.

Is it the kind of thing you wanted to achieve?
