Cannot assign to property: function call returns immutable value

Question

Consider the following example.

struct AStruct{
    var i = 0
}

class AClass{
    var i = 0
    var a: A = A(i: 8)

    func aStruct() -> AStruct{
              


        

Answer 1

Try using a class instead of a struct, as it's passed by reference and holds onto the object, while a struct is passed by value (a copy is created).
