What I wanted to accomplish

  1. Make the UITextField work
  2. Make the button work
  3. Populate the table view

Things I accomplished:

  1. Ability to type in a task (number 1 above)
  2. Add task to the todo list (number 2 above)
  3. Dismiss the keyboard after adding a todo with the button.(number 1 & 2)

    1. The keyboard does not dismiss if using the Done key
  4. Populate the table view (number 3 above)

Things I learned

Creating a separate class for a todo list made things a little bit more difficult.

struct Todo {
    var task: String
    var complete:Bool = false
}

class TodoList {
    private var todoList = [Todo]()
    
    func addTodo(todo: String) {
        let newTodo = Todo(task: todo, complete: false)
        todoList.append(newTodo)
    }
    
    func returnList() -> Array<Todo> {
        return todoList
    }
    
    func count() -> Int {
        return todoList.count
    }
    
    func getTodo(index: Int) -> Todo {
        return todoList[index]
    }
}

For example, if I needed to grab a Todo at a specific index, I had to write my own function for it. This is also the same for getting the number of todos in the todo list.

I used the class and structs to help with organization and to also keep my data out of my ViewController.swift file.

Linking a table to a view controller

Something I had trouble on was linking the table view to the view controller. I found some online tutorials to help me, but none explained how to connect the two. I will explain it right now.

While holding option, click and drag from the table view, to ViewController.swift inside the ViewController class to make an IBOutlet . Here is what my line of code looks like:

@IBOutlet weak var todoTable: UITableView!
