Learn about the various collection types available in Swift and how to choose the appropriate one for your program
Learn how to create loops in Swift, control the conditions for looping, and specify when to stop
Learn why some data can be expressed using only a broader type and how you can test for specific kinds of data before using it
Learn to use guard statements to better manage control flow
Learn to write nicely structured code that's easy to read. You'll do this by properly scoping your constants and variables
Learn when enumerations are commonly used, how to define an enumeration, and how to work with enumerations using switch statements
Learn what protocols are, when to use them, and how to write your own. Learn how to enable objects to communicate with each other and how to extend protocols to provide shared functionality across multiple types
Learn about closures, how to define them, how to use them as function arguments, and how to use some of the common functions that take closures as arguments

Use Interface Builder to add buttons, switches, and sliders to a scene. Create actions and outlets, write some basic code, and learn how these tools work together
Auto Layout and Stack Views
Learn the fundamentals of Auto Layout for building precisely designed user interfaces
Segues and Navigation Controllers
Learn how to use segues to transition from one view controller to another, how to define relationships between view controllers, and how navigation controllers can help you manage scenes that display related or hierarchical content
Tab Bar Controllers
Learn how to use tab bar controllers to organize different kinds of information or different modes of operation

Learn more about the view controller life cycle so you can understand the potential of this important class
Building Simple Workflows
Tie together the concepts youÆve learned so far to design simple workflows and familiar navigation hierarchies
App Anatomy and Life Cycle
Learn more about the different life cycle states and the delegate hooks for executing logic as the app moves through each state
Model View Controller
Learn how to organize files, structures, and classes into a design pattern called Model-View-Controller
Learn the basics of creating table views in an iOS app
Intermediate Table Views
Learn how to customize your table views with custom cells, dynamically insert and remove cells, use static table views to present forms or other nonchanging lists, and allow the user to swipe to delete cells
Learn how to implement data persistence using NSCoding, a protocol for saving files to your app's Documents directory.
System View Controllers
Discover how to incorporate a variety of system view controllers for displaying alerts, sharing content, sending messages, and accessing the camera and photo library on an iOS device.
Building Complex Input Screens
Learn how to use a combination of static and dynamic table views. Also learn to use controls and views to build custom workflows that put an elegant face on any kind of business information
