Every lesson is crafted to teach how Combine really works — with visuals, code demos, and advanced use cases that go far beyond the basics. By the end, you’ll think reactively, write more scalable code, and finally feel at home in Combine’s world
Combine
Combine isn’t just another framework — it’s the backbone of modern, reactive iOS development. But most developers barely scratch the surface. This course dives deep, revealing how to harness time, data, and logic using Combine’s powerful operators, lifecycle control, and SwiftUI integration. You’ll go beyond the buzzwords and learn the real techniques used to build fluid, async-driven apps — with precision and confidence

What You’ll Learn
Combine: Introduction, Basics, Publishers & Subscribers: Start from the core. Understand what Combine really is, how publishers and subscribers communicate, and how this elegant, declarative system transforms iOS development forever
Combine: AnyCancellable: Master lifecycle management using AnyCancellable. Learn how memory is tied to Combine pipelines, how to cancel them correctly, and why retention can break your app if not handled properly
Combine: Sequence Operators: Operators like first, last, prefix, dropWhile seem simple — but when combined with asynchronous data and backpressure, they become a
powerful toolset. You’ll master them all, including try variants and edge-case handling.
Combine: SwiftUI Integration: Connect Combine to SwiftUI the right way. Learn how @Published and ObservableObject sync data with UI, and how Combine powers the reactivity behind SwiftUI — including pitfalls most developers miss.
Combine: Accumulating & Reducing: Build smart, memory-efficient pipelines with scan, reduce, collect, and allSatisfy. Understand how to aggregate and summarize data on the fly, and how these operators behave across time and demand.
Combine: Timing Operators: You’ll finally get control over time in async programming. Learn debounce, delay, throttle, measureInterval, retry, and erase ToAnyPublisher. Each one gives you fine-grained timing and retry logic that most devs never touch.
Combine: Basic Publishers: You’ll learn far more than just Just. Understand how publishers like Sequence, Optional, Empty, Fail, Record, Future, and Defer work under the hood — and when to choose which in real-world scenarios
Combine: Basic Subscribers: Go deep into sink, assign, and custom subscribers. You’ll learn how subscribers manage demand, cancelation, and delivery — and how to
build your own custom subscription flow from scratch.
Combine: Cancelation & Custom Subscriber Lifecycle: Understand the full lifecycle of a Combine stream — from creation to cancelation. You’ll see how to build your own finely-tuned subscriber logic that handles events with surgical control.
Combine: Subjects: Subjects are the bridge between imperative and reactive. Learn PassthroughSubject, CurrentValueSubject, and their real power controlling data manually without breaking reactivity. You’ll also explore edge behaviors, timing, and threading
Combine: Filtering & Transforming: Learn to reshape your data pipelines using map, compactMap, tryMap, replaceNil, and replaceEmpty. You’ll not only know how they work — but when they unlock clarity and control in complex flows.
Combine: Foundation Publishers: Go beyond the docs. Master how Combine integrates with Timer, URLSession, NotificationCenter, and KVO — and how to build real,
asynchronous apps that stay clean, predictable, and testable
Combine: Combining Publishers: This is where reactive logic shines. Master combineLatest, merge, zip, share, and multicast to synchronize multiple data streams, reduce duplication, and coordinate async tasks with elegance
