Using String in another swift class - ios

Question

I am trying to use the array of strings that is named "theList" in another class in my project. I understand that the variable is declared within a method and therefore not of global scope. But how can I fix that? I have tried a few things and nothing is working. What is the best way to accomplish this?
EDIT: All I want to do is set "theList" equal to "Body"

I hope this clears it up a little bit, and I can select an answer. Thanks to everyone!

Answer 1

I think if you want to access that list outside of the function you should simply make it a variable of the class.
class TaskManager: NSObject {
//Sets up array of Tasks
var tasks = [task]()
var theList = [String]()
//Add Task Function
func addTask(serial: String){
tasks.append(task(serial: serial))
theList = tasks.map({ (task) -> String in
return task.serial
})
}
}

Answer 2

Your best way to do this is to look at the scope of your class and the declaration. Define your list in a place that has scope everywhere you want to use it, or make it global. That's how I do this kind of task. Sometimes add it to a higher level class declaration, and sometimes I make it global to, say, the entire program. Depends on the task and my outlook at the time of coding.

Answer 3

Let you function return the results of adding the task then:
class TaskManager: NSObject {
// declare your variables
func addTask(serial: String) -> [String] {
// put your realisation
}
}
or make your variable with serials available publicly:
class TaskManager: NSObject {
var tasks = [Task]()
public var serials = [String]()
func addTask(serial: String) {
// put your realisation
// save the results to serials
}
}
and then access it via the instance.

Adding theList Variable above class made it global.
Then I had to remove let from the addTask function.
//Add Task Function
func addTask(serial: String){
tasks.append(task(serial: serial))
let theList = tasks.map({ (task) -> String in
return task.serial
}).joinWithSeparator("\n")
Became
//Add Task Function
func addTask(serial: String){
tasks.append(task(serial: serial))
theList = tasks.map({ (task) -> String in
return task.serial
}).joinWithSeparator("\n")
The final code is as follows.
import UIKit
var theList : String = String()
var taskMgr: TaskManager = TaskManager()
struct task {
var serial = "Un-Named"
}
public class TaskManager: NSObject {
//Sets up array of Tasks
var tasks = [task]()
//Add Task Function
func addTask(serial: String){
tasks.append(task(serial: serial))
theList = tasks.map({ (task) -> String in
return task.serial
}).joinWithSeparator("\n")
do {
//try tasksString.writeToFile(pathToFile, atomically: true, encoding: NSUTF8StringEncoding)
print(theList)
}
}
}
