Swift Talk

A weekly video series on Swift programming.

#63 Mutable Shared Structs (Part 2) 22:59

We continue to experiment with our hybrid struct/class data type and incorporate the ability to add and remove more fine-grained observers.

#61 Mutable Shared Structs (Part 1) 30:10

We build an experimental data type that combines the advantages of both structs and classes. It allows shared mutable state while preserving the features of structs to make easy copies and observe changes.

#55 Sorted Arrays with Binary Search 26:51

Károly joins us to improve our sorted array implementation from episode #35 using binary search. We benchmark both implementations to learn about their real-world performance.

#31 Mutating Untyped Dictionaries 15:14

We solve an interesting challenge from a Stack Overflow question: mutating a nested untyped dictionary. In the process, we discuss the mutability of value types and the concept of l-values.

#21 Structs and Mutation 16:07

We look at multiple ways to change structs: mutation, functional chaining, and inout parameters. We discuss how they differ at the call site and why they’re all equivalent.

#17 Ledger GUI Architecture 18:31

We connect multiple view controllers using a central coordinating object and callback functions. Then we refactor the UI state into its own struct to simplify the control flow.

#1 Networking 22:49

We explore an alternative approach to building the networking layer of an app. We make use of Swift's generics and structs to end up with simple, testable code.
