If we want our apps to succeed, we have to get our buttons spot on. They allow our users to navigate around our apps, show their preferences and define their own personal user journeys. Not only that, they play a crucial role in the overall look and feel of our apps, and enhance our overall brand image if we get them right.

The SwiftUI vs UIKit question may seem like a sticky web of pros, cons and competing nuances. But ultimately, it boils down to one thing: Which framework is best for my specific app? The answer shouldn’t be based on hype or trends. It should be based on your own real-world parameters, like team size, UI complexity and long-term maintenance. Understanding your own development realities is crucial to making the right choice between SwiftUI and UIKit.

It goes without saying that crash debugging is crucial. For app quality, for App Store ratings, for compliance with Apple’s ecosystem. And if you’re new to the concept of debugging (or you simply want to top up your knowledge) this guide will give you a complete toolkit of tips and instructions. We’ll explain the most common iOS crash debugging scenarios and show you how to diagnose and fix them quickly.

And more to the point… why do I need to read a whole blog post on it? Two good questions. Well when we’re debugging, stepping removes the guesswork by letting us watch the logic unfold step-by-step. We can pause the code, go through the execution one instruction at a time and isolate the exact point where the bad stuff happens. This is one of the most reliable ways to understand why a bug happens, not just where it shows up. It also shines a microscope on our code flow, showing us.

The JavaScript debugger statement is a built-in keyword that tells the JavaScript engine to pause execution at a specific line of code. When execution stops, you can inspect variables, function scope, and the call stack using developer tools. It is commonly used during development to analyze how values change and where logic breaks, without relying on repeated logging or assumptions. No more guesswork. No more partial truths.

SwiftUI Previews show us how our app will look out in the wild and let us make changes in real time, without emulators. But that’s not the full story. The full benefit of SwiftUI Previews lies in declarativeUI, which allows us to dictate the final state we want to achieve and handles all the process stuff itself. This is a game-changer for developers, allowing us to shift our focus from ‘how’ to ‘what’.

Whether you’re building your first iOS app or improving user engagement, understanding push notifications is essential. They’re how apps stay connected with users, delivering updates, reminders and alerts even when the app itself isn’t running. In this guide, you’ll learn how to implement iOS push notifications from setup to debugging, using Swift and Apple Push Notification Service (APNs) in a real app.

Exceptions are inevitable. It’s how we deal with them that matters. An effective exception handling regime is the difference between an app that only works in sandbox and one that can adapt and scale in the real world. JavaScript can throw up all kinds of weird and wonderful exceptions, because it runs in inherently unpredictable environments. So we’ve put together this guide to give you a clear, repeatable plan for handling them.

An effective JavaScript debugging regime is essential if we want to build responsive, reliable and highly-rateable Android apps. JavaScript doesn’t enforce types at compile time (unlike Swift) and this means errors often happen quietly, when users are already feeling them. So it’s vital that we debug pre-emptively, using knowledge rather than guesswork.
