Non-crashing bugs don’t make your app crash, but they can ruin the user experience and hurt your app’s ratings. Fixing these issues is critical to keeping users happy. Here’s a quick rundown of the most common non-crashing bugs and how to address them.

Concurrency means running multiple tasks at the same time, and it’s a great way to ensure our apps stay responsive. Swift 5.5 introduced structured concurrency and the closely related concept of async/await to improve the management of asynchronous code, part of a wave of changes designed to ensure simpler code, improved error handling and automatic task lifecycle management.

Debugging React Native apps can be challenging, but using the right tools and techniques makes it manageable. Here’s what you need to know.

Modern app users don’t tolerate glitches — speed and stability are non-negotiable. Debugging across multiple Android devices, however, can be tedious if done manually. That’s why developers rely on Android Debug Bridge (ADB) to streamline development. With ADB, we can: In this guide, we’ll cover what ADB is, how it works, installation steps, and the most useful commands for debugging Android applications.

In less than 20 years, mobile apps have grown from a bright new idea to a cornerstone of our daily lives. And while Android accounts for the lion’s share of the market, iOS usage continues to grow exponentially: in 2024 alone, iOS apps and games were downloaded around 35 billion times. The Apple App Store is both a shop window and a marketplace for this global industry. But as iOS developers, how do we actually submit a mobile app to the store?

Mobile crash reporting keeps apps reliable at scale, helping developers root out the cause of problems and prevent them recurring. In this guide, we compare the top mobile crash reporting tools for 2025, including Android-friendly and cross-platform options, to help you choose the right fit for your workflow. You’ll find: This guide focuses on what truly matters for real development teams, not just feature lists. And yep, we’re slightly biased, as one of the solutions is our own.

Sealed classes are a special kind of class in Kotlin, used to create restricted hierachies — where the full list of sub-classes is strictly limited, and known in advance. This is particularly useful when we want to enhance the power of Kotlin’s when statement, model a type that has a fixed set of possible variations, or represent a fixed group of states or outcomes (such as network responses, UI states and form validations).

It’s one thing to build an app. It’s another to make sure it actually works the way people expect – on real iPhones, in the wild, under all kinds of conditions. That’s where iOS app testing comes into play. Crashes, broken layouts… these are the kinds of things that can tank your reviews fast. If you want to avoid that, you need to test the app properly. And that’s exactly what we’re going to walk you through in this short guide.

Jetpack Compose is Android’s modern UI toolkit. It unifies and simplifies the experience by consolidating state and logic in the rendering with a more declarative approach. Among its most notable features is a powerful animation framework that helps developers create fluid and performant animations with ease. Jetpack Compose allows you to easily inject animations into your UI, which is a great way of providing visual feedback and enhancing interactions that directly affect the user experience.

Swift extensions are one of the most useful tools in iOS development, allowing us to add new functionality to existing types without subclassing or rewriting code. In this guide, we’ll break down how extensions work, why they matter, and how to use them effectively. You’ll learn: By the end, you’ll know how to use extensions to write cleaner, faster, and more maintainable Swift code.
