AppDelegate doesn't access updated struct variable - Swift

I have a struct which looks like this

struct myStruct {
    var array1: [String]
    var additionalInfo: String?
    var array2: [String]
}

var appendMe = [myStruct(array1: ["Value1"], additionalInfo: nil, array2: ["Value1","Value2"])]

in MainViewController i append it with additional values, but when i try to access them from the AppDelegate, for instance like this

appendMe[array1.count-1].array2[0]

I always keep getting the original values set in the struct before the update. Just like Xcode creates a separate instance of the struct for MainViewController and AppDelegate.

How to i fix this issue?

Thank you!

Structs are passed by value in Swift, not by reference. Your main view controller is modifying a copy of the struct, not the one you think.
