Inside iOS Dev

Inside iOS Dev treats iOS development as a craft practised in code, not just discussed. Many episodes are partly screencasts: a project is open, and it changes as the hosts talk, so the show exists as audio and as YouTube video. Alex Bush and Sandeep Aggarwal host the paired episodes, and Alex takes some screencasts on his own. The mocking material shows the method best. It starts with a small SwiftUI app that lists images and titles from a server. The hosts define the model the backend should return, then replace the real request service with a mock that returns data of their choosing. The list appears instantly, because nothing is waiting on a network. The lesson under the demo is structural: the view model depends on a protocol, not a concrete class, so the swap costs almost nothing. Framed that way, mocking becomes a way to keep building UI while a backend is unfinished, not only a testing tool. A companion episode goes further. 'Generating Mocks with Sourcery' extends an earlier unit-testing example, moving from stubbing return values to checking which methods get called and in what order. It then sets up Sourcery through a YAML config, testable imports and a script that can be called from the project root. Refactoring gets the same close treatment. 'Refactoring Large Initializer in Swift. Part 1. Dependency Injection with Default Values and Properties.' began as a video, and Alex warns up front that the audio may be missing some explanation without the code in view. The problem is an object whose initializer creates fresh instances of every injected service each time it is built. Guests widen the lens. Robert Martin, known as Uncle Bob, appears in 'Clean Code’s Impact with Uncle Bob', and the conversation lays down a blunt rule for old, messy codebases: add tests gradually, expect the cleanup to take months or years, and never ask management for three months to fix everything at once. The talk then turns to a team where management does allow time for refactoring, which the speaker says they had rarely seen elsewhere. 'iOS Interview Tips from Engineering Manager and Senior Engineers' brings in Murali, a senior iOS developer, and Aina, an engineering manager. The take-home assignment gets most of the practical advice: work out how the networking and business logic can be tested, finish the mandatory items before the good-to-have ones, and ask the recruiter when the instructions are unclear. Then there is 'WWDC 2022 Devs Reaction', which the hosts introduce as raw, almost unedited and partly emotional. It stops on Swift package plugins, SwiftLint flagging missing documentation and plugins running in Xcode Cloud, and one host wishes plugins could run when a file is saved, without a full build.
