iOS DEV: "My CI build with 3rd-party dependencies is too slow 😱" 👇

Have you ever experienced slow CI build times - sometimes taking even longer than your local builds?!

To become a complete senior iOS developer, you need to know how to correctly configure your CI pipeline, especially with 3rd-party dependencies via Cocoapods, Carthage, and SPM.

So watch this mentoring session now to learn how to speed up a slow CI pipeline to deliver better iOS apps faster.

Did you know your iOS apps could have race conditions when refreshing Auth Tokens? 👇

To become a complete senior iOS developer, you need to know how to store and refresh access tokens securely and without race conditions.

Also, how to use the Decorator design pattern to sign requests across multiple features without duplicating code everywhere.

So watch this mentoring session now to learn how to refresh tokens correctly using Swift Async/Await and Actors:

Have you considered transitioning parts of your existing app using UIKit to SwiftUI? 👇

Many iOS devs and iOS teams have difficulties migrating because of custom flows used in the app, such as navigation and UI behaviors that aren't easily reproducible with SwiftUI.

To become a complete senior iOS developer, you need to know how to dig and experiment with ideas to determine the trade-offs of such transitions, assessing the best choice for your team in the short and long term.

So watch this mentoring session now to learn how to choose the right approach/framework to maintain or even boost your team's productivity when there is a significant paradigm shift in our tools, like the adoption of SwiftUI.

"Should I extract my code into reusable components to avoid duplication?" 👇

Well, it depends...

Usually, yes. We don't want to duplicate UI code because every time we need to make a change, we'd have to remember to update it in EVERY duplicate component. And this is inefficient and error-prone.

But in large modular apps, we also don't want to couple all feature modules with a shared UI module. Otherwise, changing the shared module because of "Feature A" will also impact "Feature B" directly. This would also be inefficient because it would increase build times and require synchronization between feature teams.

Is there a solution to this problem?

Yes! There's a specific way of creating shared UI modules without increasing coupling between modules.

To become a complete senior iOS developer, you need to know when it's the right time to extract duplicate code into a shared module and how to do it efficiently without increasing coupling between feature teams.

So watch this mentoring session now to learn when and how to create a shared UI module.
