Learn how to manage asynchronous work in iOS the reactive way: using Combine! Master the techniques and best practices to write declarative Combine code in playgrounds and complete iOS app projects.
Getting Started
Introduction
7:17
FREE
Welcome to the course! Find out a bit about the history of reactive programming, and a high level overview of Combine.
1
Publishers and Subscribers
8:57
Learn about Publishers and Subscribers, which are the endpoints of the Combine pipeline, and how they work with one another.
Subscriber Operators and Subjects
11:51
Learn about some built in operators for Subscribers as well as Subjects, which help connect the imperative and declarative world.
Challenge: Create a Blackjack Dealer
6:12
In this hands-on challenge, use your knowledge of publishers and subscribers to create a blackjack dealer.
Conclusion
1:19
Recap what you learned about publishers and subscribers, and gear up for the rest of the course.
Transforming & Filtering Operators
Introduction
1:42
Learn about what Operators are in Combine, and get an overview of which ones you’ll learn about in this part of the course.
Transforming Operators
9:08
Collect, map, replaceNil and replaceEmpty are basic operators that can be used to transform data into another form.
More Transforming Operators
7:59
Learn about how the scan and flatMap operators can be used in your code to do more advanced transformations.
Challenge: Create a Phone Number Lookup
3:07
In this hands-on challenge use your knowledge of transforming operators to lookup a phone number in a contact book.
Filtering Operators
7:46
Basic filtering operators like filter, removeDuplicates, ignoreOutput and compactMap can be used to narrow down which values get sent downstream to subscribers.
More Filtering Operators
8:25
Learn about more filtering operators: first(where:), last(where:), drop, and prefix, which give you additional ways to keep values from traveling downstream.
Challenge: Filter All the Things
1:56
In this challenge, use your knowledge of filtering operators to slim down an array of numbers to a predefined set of values.
Conclusion
0:36
Review what you’ve learned about transforming and filtering operators.
Combining Operators
Introduction
0:48
You’ve learned about several operators already, but there’s more! In this part, you’ll learn about combining operators.
Prepend
9:21
Discover the prepend family of operators, which consists of prepend(Output), prepend(Sequence), and prepend(Publisher).
Append
8:21
Now check out the append family of operators, which consists of append(Output), append(Sequence), and append(Publisher).
Challenge: Append and Prepend
3:03
In this hands-on challenge, turn your old-school 7 digit phone number into a modern day number using combining operators.
More Combining Operators
1:57
Learn how you can use operators such as switchToLatest, merge(with:), combineLatest and zip to perform more advanced combinations of data from publisher.
Operator Examples
12:21
In this episode, see examples of switchToLatest, merge(with:), combineLatest and zip in a Swift playground.
Challenge: Advanced Combining
3:30
In this hands-on challenge, build upon the last challenge to interleave multiple arrays of data together.
Conclusion
0:47
Let’s recap the different combining operators you learned about in this part of the course.
Timing, Scheduling and Sequencing Operators
Introduction
0:42
Learn about the final set of operators we’ll cover: timing, scheduling and sequencing operators.
Delay and Collect
10:43
The basic timing operators like delay and collect do just what they advertise – delay values from a publisher and collect a series of emitted values.
Debounce and Throttle
10:28
The debounce and throttle operators come in handy when collecting data such as a person typing, keeping you from checking after every keystroke.
Timeout and measureInterval
10:17
Learn how the timeout operators can be used to cause a publisher to time out and complete, and measureInterval to measure the interval between emissions.
Challenge: Collect Values by Time
3:13
In this hands-on challenge, use your knowledge of timing operators to decode a message from a set of mysterious data.
Scheduling Operators
6:46
Learn about the schedule and receive operators, which can be used to tell Combine which Scheduler to use when running the operations.
Sequencing Operators
8:59
Sequencing operators such as max, min, count and output can give you information on the sequence of emitted values as a whole.
Challenge: Sequence Operators
2:38
Challenge time! Use your knowledge of sequence operators to give a golfer a report on their golf game.
Conclusion
2:07
