How to call a function within a structure and a class?

Anonymous User168613-Oct-2014
I have two files: ClassA.swift and ClassB.swift
classClassA: NSObject {
        structStructA {
            func talk(string: String) {
                println("I say: \(string)")
            }
        }
    }
 
 
    classClassB: NSObject {
        func makeItTalk(string: String) {
            ClassA.StructA.talk("Hello") <--------------
        }
    }

I get the following error message

Type 'ClassA.StructA' does not conform to protocol 'StringLiteralConvertible'

Any idea why? Is it actually something than can be achieved?

You are using talk as static method, but it is declared as instance method. Change to:
classClassA: NSObject {
        structStructA {
            static func talk(string: String) {
                println("I say: \(string)")
            }
        }
    }

You are accessing StructA in a static context, whereas you need an instance of it:

classClassB: NSObject {

        func makeItTalk(string: String) {

            var myStruct = ClassA.StructA()

            myStruct.talk("Hello")

        }

    }

Alternatively, if your goal is to access that method statically, just declare it as a static struct method:

static func talk(string: String) {

        println("I say: \(string)")

    }
