Understanding how your apps behave in production is a fundamental part of our jobs as iOS engineers. We need to gather log events in order to investigate and reproduce issues that customers run into. Here’s how you create a log service with a clean architecture that’s modular and easily extensible.
Monitoring the behavior of your app’s users is critical to the success of your app. If the only feedback you get from your users are App Store review, now is the right time to start using analytics. We’ll go over how you create an analytics service that’s modular and easily extensible using a clean iOS architecture.
Feature toggling is essential for keeping your apps flexible in production. Sometimes you want to try ideas fast to see if they stick. Maybe you want to split test two ideas and see what performs the best. Whatever the case may be, the feature toggling service should be highly scalable and not be a bottleneck in your workflow. Here’s how you create a feature toggling service with a clean iOS architecture.
A common frustration with the iOS platform is that resources are accessed using magic strings. In practice, this means you’ll find out if an image, icon, localized string etc. exists at runtime. Either by seeing what you were hoping for or getting a hard crash. Let’s fix this by introducing your new best friend – R.swift.
RxSwift is well known for having a steep learning curve. But taking the time to learn it can easily be the next significant leap in your development abilities. We’ll cover the basic concepts of the library to quickly get you up to speed.
RxSwift provides plenty of options for joining your observable sequences together. Let’s go over the 5 most important combining operators you’ll likely use the most.
Transforming operators in RxSwift serve the purpose of preparing data coming from observables before it reaches the subscribers. Let’s cover this type of operators and look at 3 operators you will be using all the time.
