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. https://essentialdeveloper.com/articles/how-to-speed-up-slow-ios-ci-with-cocoapods-carthage-spm-dependencies-live-dev-mentoring

Many iOS devs believe they will earn a raise or get paid more if they work longer hours. But it rarely works because... 👇 1) Your boss may not perceive your extra hours as extra work. They may not even know you're doing extra hours. Worst yet... What if they get used to your extra delivery pace? It'll be hard to go back to the normal number of hours later as they'd think you "slowed down." When the "extra hours" becomes the norm, you actually DECREASE your hourly rate because you have to work more hours to get paid the same. 2) Fatigue. You won't be able to sustain long hours forever, and the quality of your work will decrease over time. So chances of improving and getting a significant raise will decrease. 3) It doesn't scale. We all have only 24h a day with limited time to work - so you can't keep increasing your salary by working more hours forever. A better way of increasing our income as iOS devs is to deliver more value with less effort. To become a complete senior iOS developer, you need to know better ways of increasing your income by delivering more value to your clients and team with less effort. So watch this mentoring session now and learn how to increase your income sustainably without working more hours: https://www.essentialdeveloper.com/articles/how-to-increase-your-senior-ios-dev-income-without-working-more-hours

Have you ever had doubts or difficulty modularizing your iOS apps' architecture? For example... 👇 Should you separate your app vertically into feature modules? Or maybe in horizontal layers like Models, Services, Views, etc.? Or perhaps using a mixture of both horizontal and vertical slicing? And which one will improve build times? To become a complete senior iOS developer, you need to know when and how to extract your code into isolated modules that are easy to develop, test, compose, and maintain. So watch this mentoring session now to learn when and how to use modularity to improve your codebase and your team's productivity. https://www.essentialdeveloper.com/articles/senior-ios-dev-modular-app-architecture-review-live-dev-mentoring

Ever had to implement a very complex iOS app flow? For example... 👇 • The app is accessible without an account, but some content is locked behind permissions controlled by admins. • If the user wants to access locked content and is not logged in, show the login screen with the option to create a new account. • Once logged in, check if they have permission to access the content. • If they have access, show the content. • If not, show a flow for requesting permission to an admin... • Some content may require additional flows, such as accepting terms and conditions... And so on. Those flows can get really long and complex. And new rules may be added at any time. So if we don't manage the complexity well, we'll end up with huge classes with thousands of lines of messy code. To become a complete senior iOS developer, you need to learn how to implement complex flows in a simple and maintainable way. So watch this mentoring session now to learn how to design independent flows that are easy to implement, test, maintain, compose, and extend. https://www.essentialdeveloper.com/articles/architecting-complex-ios-app-flows-with-senior-devs-live-dev-mentoring But hurry up because this video is publicly available only until July 4th, 2022. After that, it'll only be available to students of the Essential Developer Academy.

So watch this mentoring session now and learn practical Xcode/Instruments guidelines to profile and improve performance issues more efficiently 👇 https://www.essentialdeveloper.com/articles/how-senior-ios-devs-profile-and-solve-performance-issues-with-instruments-app-live-dev-mentoring

Ever wondered how many iOS teams keep releasing app versions continuously with confidence? 👇 One key aspect of Continuous Integration (CI) and Continuous Deployment (CD) is automated testing. Fast and reliable automated tests allow iOS teams to be much more productive and iterate much faster in the development cycle. So to become a complete senior iOS developer, you need to know how to write fast and reliable tests. And to be fast and productive at writing tests, we recommend following Test-Driven Development (TDD). So watch this mentoring session now to learn simple techniques to get started with TDD without getting stuck. https://www.essentialdeveloper.com/articles/how-to-start-with-tdd-to-become-a-complete-senior-ios-developer-live-dev-mentoring

iOS app navigation can lead to high coupling between features. Have you ever wondered how senior iOS devs handle navigation in large modular apps? When modularizing large iOS apps, the goal is to decouple features as much as possible so we can develop, maintain, test, and test them in isolation. Also, a common use case is to reuse independent modules across apps. But what about when you need to navigate from one feature to the other? If we navigate from feature A to B directly, there's coupling from feature A to B. So they can't be independent. If the features need to be independent, the Composition Root is the place to compose the modules without coupling them. But we don't want navigation logic in composition, factories, or any other composer types to avoid spreading logic into unrelated components. To become a complete senior iOS developer, you need to know strategies to navigate between independent features without coupling them. So watch this mentoring session now to see Flows/Coordinators implemented in practice to solve this problem 👇 https://www.essentialdeveloper.com/articles/how-senior-ios-devs-extract-navigation-logic-into-flows-coordinators-live-dev-mentoring But hurry up because this video is publicly available only until May 23rd, 2022. After that, it'll only be available to students of the Essential Developer Academy.

Have you ever felt like Apple frameworks such as StoreKit for in-app purchases are hard to use and complicate your code? 👇 For example, you may have to deal with many confusing optional properties (that should never be nil`). Or callbacks with optional results - even though there's no reason to ever get `nil back in your specific case. This is not because Apple's framework design is bad. But think about it... Apple frameworks need to accommodate *every* app. So those frameworks need to be very flexible and offer a wide variety of features. And this brings complexity. But your app may need only a tiny subset of the features Apple frameworks (or any other 3rd-party framework) provide. To become a complete senior iOS developer, you need to know how to separate your features from frameworks' complexity in such cases. To do so, you can model your app needs with plain Swift types and clean abstractions - without ever referencing specific framework details in your features. And you "plug" or "inject" frameworks into your features later. This strategy is a combination of "Dependency Inversion" and other design principles and practices applied in unison. This is a common strategy in Domain-Driven Design (DDD) - where you design/model your core domain to be decoupled from frameworks and infrastructure complexity. This makes your core domain logic much easier to implement, maintain, understand, and test.
