Deep Dive iOS 27 & SwiftUI 6: 90-Hour Project-Based Course (Udemy.com)

Deep Dive iOS 27 & SwiftUI 6

Learn Swift and SwiftUI by building real-world applications for iPhone, iPad, Mac, and Apple platforms.

This is a 90-hour, project-based iOS development course covering Swift programming, SwiftUI, MVVM, API integration, async/await, localization, SwiftData, Core Data, Charts, MapKit, animations, gestures, push notifications, Core ML, Create ML, Foundation Models, App Intents, and much more.

The course is actively being updated for Xcode 27, iOS 27, iPadOS 27, and macOS 27, with new material added as Apple's latest technologies become available.

You don't need previous Swift or iOS development experience. If you already know how to program, you can move quickly through the Swift fundamentals and start building applications.

What You'll Learn

• Learn Swift programming from the fundamentals through more advanced features

• Build modern applications using SwiftUI

• Understand SwiftUI's data flow with @State, @Binding, Observation, @Observable, and more

• Use MVVM architecture to organize larger applications

• Build apps for iPhone, iPad, and Mac

• Make API calls using URLSession, async/await, and Swift concurrency

• Work with SwiftData and Core Data for local data persistence

• Build multilingual applications using localization and String Catalogs

• Create sophisticated animations, transitions, and gestures

• Work with Swift Charts, including line, bar, area, pie, donut, and 3D charts

• Integrate MapKit into your applications

• Work with local push notifications

• Explore Apple's Foundation Models and on-device AI

• Use Core ML and Create ML

• Learn about App Intents

• Work with images, AsyncImage, and image caching

• Build responsive interfaces that adapt to different screen sizes and Apple platforms

Learn by Building Real Apps

This is a project-based course.

Rather than spending the entire course watching lectures about Swift syntax, you will use what you learn to build applications.

The projects start simply and gradually become more sophisticated. Along the way, you will encounter real problems that iOS developers need to solve: managing state, navigating between screens, working with APIs, storing data, adapting layouts to different devices, handling gestures, localizing applications, and structuring larger projects.

Some of the major projects include:

• Greetings App — multilingual SwiftUI app supporting light/dark mode, dynamic language changes, iPhone, iPad, Mac, localization, animations, and AppStorage

• Calculator App — responsive interface supporting light and dark mode

• Weather App — API integration using URLSession, JSON, async/await, and MVVM

• Chinese Counting App — API calls, multilingual text-to-speech, modern navigation, MVVM, iPhone, iPad, and visionOS

• Activity Tracker — SwiftData combined with charts, including pie and donut charts

• Alarm App — local notifications, gestures, localization, and a more complex UI

• Conway's Game of Life — Canvas, Timeline, MVVM, Mac development, drag and drop, and a pattern editor

• Tip Calculator — responsive layouts, multiple devices, localization, and custom shapes

• Flashcards App — interactive gestures including dragging

• Mystic Puzzle — a 15-tile puzzle with animations, gestures, JSON persistence, and a Mac-based shape editor

There are also many smaller projects and focused examples covering individual SwiftUI and iOS development techniques.

Swift Programming

We begin with the Swift language so that you understand the code you will be writing throughout the course.

Topics include:

• Variables and constants

• Arrays and dictionaries

• Structs and enums

• Tuples

• Loops and control flow

• guard

• Functions

• Closures

• Higher-order functions

• Functional programming

• Raw strings

• Coding exercises

If you already know how to program, you can move through these sections quickly.

SwiftUI Fundamentals

You will learn the building blocks of modern SwiftUI development, including:

• VStack, HStack, and ZStack

• Grids and lists

• Text and text fields

• Buttons

• Frames and alignment

• Navigation

• Tab views

• Gradients and mesh gradients

• Images and AsyncImage

• Light and dark mode

• Tinted app icons

• Responsive layouts

• Multiple screen sizes

• iPhone, iPad, and Mac interfaces

One of the goals of the course is to get you building a real application early, rather than making you wait until the end of the introductory material.

Data Flow and MVVM

Data flow is one of the most important concepts to understand when developing with SwiftUI.

You will work with:

• @State

• @Binding

• Observation

• @Observable

• @Bindable

• Observable objects

• Application state

• MVVM

The course then uses MVVM throughout many of the larger applications, giving you practical experience with this common architecture.

Networking and Async/Await

Modern applications frequently need to communicate with web services.

You will learn how to:

• Make API requests with URLSession

• Decode JSON

• Use async/await

• Work with Swift concurrency

• Refresh network content

• Display remote data in SwiftUI

• Combine networking with MVVM

The Weather App and Chinese Counting App provide practical examples of these techniques.

SwiftData and Core Data

Learn Apple's technologies for storing data locally.

You will work with:

• SwiftData

• Core Data

• JSON persistence

• Persistent application state

• MVVM with persistence
