Build your first iOS App in Swift

Begin building your first iOS app in Swift by following twenty video tutorials, code along step by step, and complete a final project that applies learned skills.

Install and open Xcode, create a new iOS single-view project in Swift, then explore the project structure and run it on a simulator to verify the starting screen.

Learn how view controllers form controller hierarchy in storyboard, connect elements like text fields, create multiple controllers, and map them to Swift files using the class inspector and storyboard IDs.

Explore segues and navigation controllers to transition between view controllers, using a modal segue for full-screen tasks and a navigation controller to push and pop through a navigation stack.

Learn to build a to-do list with a table view controller that hosts a table view, uses a data source, and is set up in storyboard within a navigation controller.

Build a todo list in swift by defining a task data model with categories, creating tasks, populating a data source, and displaying them in a table view.

Connect the to-do list to its detail view by creating a segue, selecting a cell, and passing the chosen task through prepare for segue to the detail controller.

Subclass the table view cell to enable customization and create a task table view cell for styling. Organize controllers, cells, and models into folders and set the row height.

Hook up the task table view cell by dequeuing and casting to TaskTableViewCell, then bind the task data to the title and subtitle labels.

Add a plus button to the navigation bar to present a task creator view controller, then save and reload new tasks into the dynamic table view.

design the task creator view by adding title, due date, and type fields, wiring outlets, and using a stack view with auto layout and a navigation bar for adaptable layouts.

Learn to collect user input with UITextFields in a Swift iOS app by wiring controls, implementing the text field delegate, dismissing the keyboard on return, and configuring placeholders.

Learn to use a UIPickerView to replace text field input, configure the delegate and datasource, and bind a four-item task type list to selections.

Learn how to add and configure a UIDatePicker to capture a task due date, connect it to a text field, handle value changes, format the date, and update the UI.

Improve the user experience by repositioning the navigation bar with constraints and a delegate, and by adding a tap gesture to dismiss keyboards and date pickers.

Validate title, due date, and task type inputs, create the new task, dismiss the view, and handle errors with an alert and a delegate to update the to-do list.

Explore protocols as blueprints and implement the delegation design pattern to pass new tasks from a task creator to a to-do list, using Swift protocols, extensions, and delegates.

Learn to implement the TaskCreatorDelegate, add an optional delegate property, and notify didCreateNewTask when a new task is created in the to-do list.

Style the detail view controller by adding labels, configuring fonts, and applying auto layout constraints to display the task title, type, and due date across device sizes.

Polish your iOS to-do app by adding a navigation title, reducing cell height, and showing a programmatically created empty-state label as the table background when the list is empty.
