Swift for Beginners - Create your first iOS App with Swift

Download and install the latest Xcode, explore its interface, and learn how joining the iOS developer program enables testing on real devices and App Store distribution.

Create a new single view iOS app in Xcode and configure its name, bundle identifier, and language. Browse the project navigator and storyboard, then run the app in iOS simulator.

Create a new iOS project and run it in the simulator to print hello world to the console, then use a playground for immediate results in the preview pane.

Explore the fundamentals of programming in Swift using playgrounds to learn variables, constants, and program flow, building the foundation for iOS app development.

Explore how to assign and update values in Swift using var and let, and see constants stay fixed while variables update in an Xcode playground.

Learn how Swift infers data types for variables, declare strings, integers, booleans, and floats, and perform basic type conversion from strings to numbers.

Explore Swift basics by performing arithmetic with variables and constants, including plus, minus, multiply, and divide. Learn string concatenation, interpolation, and converting numbers to strings for dynamic displays.

Explore arrays and dictionaries in Swift, learn zero-based indexing, access by position or key, and modify collections with insert and remove operations.

Apply if-else logic to control flow with temperature comparisons, braces, and print statements, and learn operators like ==, <, >, <=, >= to keep temperatures between 25 and 33 degrees.

Compare for loops and while loops in Swift: use for loops when the iteration count is known, and while loops when it’s unknown, with array and print examples.

Explore how the scope of variables and constants controls visibility. Define variables inside curly braces, avoid collisions, and ensure a variable is defined before you access it outside conditional blocks.

Explore object oriented programming by using cars to illustrate classes, properties, and methods, showing how objects embody a blueprint defined by a class.

Define a car class in Swift with color, wheels, and type, create and initialize an object, and access its properties with dot notation; relate these OOP concepts to button creation.

Define and call functions with func, pass parameters, and return values, then apply looping and area calculations, including greeting examples and triangle area computations.

Explore integrating functions into class definitions in Swift by building a car blueprint with speed property, accelerate and brake methods, and multiple initializers.

Explore optionals in Swift by building a simple person model with optional middle name and spouse, using optional binding and safe unwrapping to greet with or without a middle name.

Start your first iOS app in Xcode with a single UIViewController and a UITextField, using Interface Builder, size classes, and auto layout for universal design.

Learn to connect interface elements with code using IBOutlets and IBActions in Interface Builder, and hide the keyboard by resigning first responder.

Learn to use the UI textfield delegate to manage the return key and hide the keyboard, by connecting the delegate in code or via the interface builder.

Create a single-view iOS app using a multiline UITextView, compare it with a text field, and mirror text between two text views via delegates.

Learn how to work with multiple view controllers in a storyboard, create segues, and pass data between controllers using prepare for segue and identifiers.

Create a tiny image gallery using a UIImageView and a next button. Load three images from the asset catalog and display them with aspect fit, cycling safely without crashing.

Learn to create and present alert controllers and action sheets with UIAlertController, configure titles, messages, and actions, and handle button taps using closures.

Explore how to implement a multitouch swipe gesture recognizer in a Swift iOS app, detect bottom-to-top swipes, and present an action sheet via a UI alert controller.

Learn to add movement to iOS interfaces by using a tap gesture recognizer to move a star image view to the tap location with 0.2 second animation and ease-in curve.

Build a real-world calculator app called Swift Kelk using image assets and a storyboard, constructing a complete numpad and a display label, then run it on iPhone retina devices.

Learn to implement calculator logic by using a single numberPressed action, track waiting numbers and operations with button tags, and apply a switch statement for plus, minus, multiply, divide, equals.

Apply finishing touches to a Swift calculator app by wiring operation handling, updating the display with keypad input, and adding app icons for a polished iOS project.

Develop your Swift skills with variables, constants, if statements, loops, and object oriented programming in iOS apps using UI components; prepare for advanced topics in the next course.
