Push notifications are one of the most powerful retention tools in mobile. iOS opt-in rates average 40–45%, and apps that use push effectively can triple their long-term retention. However poorly timed, poorly crafted alerts can drain our open rates, leading to opt-outs and disengagement. When designing iOS push notifications, we need to think about engagement and retention, not just impressions.

UIKit is Apple’s primary framework for building user interfaces on iPhone and iPad. If you’ve read that it’s about to be deprecated, don’t believe the reports. In 2026 UIKit remains as integral to production apps as it’s ever been. In this guide we’ll focus on how UIKit actually works. The lifecycle timing, the navigation structure, the memory management and (our favorite) the production debugging. You’ll find it useful if you’re.

PHP applications are often tricky to debug. A combination of loose typing, complex logic and a lack of runtime visibility can make it hard to catch errors before they reach our users. But if you’re using PHP, there’s no need to stress. This guide will equip you to understand why PHP applications break, return the wrong data or behave differently across environments. We’ll cover logs, runtime checks, Xdebug, IDE tools, request debugging, and production visibility.

Xcode is the default development environment for building apps on Apple platforms. If you’re creating iOS, macOS, watchOS, or tvOS apps, you’ll end up in Xcode – whether you planned to or not. Xcode is powerful, reliable and intuitive. But it’s also opinionated. Learning how it expects you to work is often the difference between feeling productive and stuck.

JavaScript breakpoint is a pause point in code execution. Breakpoints are one of the most crucial tools available to us when debugging. Simply put, they enable us to pause our program in real time and inspect a particular chunk of code. We may have suspicions that a particular line is causing our app to crash, or simply want to check part of the call stack. Breakpoints give us this flexibility.

Choosing between Android and iOS programming shapes literally every aspect of your programming life. The way you build. The costs you face. The complexity of your testing, the strategy of your distribution and the long-term scalability of your project. Both platforms are mature and capable of supporting complex, high-performance applications, but there are trade-offs.

Breakpoints are one of the most useful tools we can call on when we’re debugging applications. If you’re not familiar, they allow us to pause execution and examine what the program is doing at that moment. And Android Studio offers a whole bunch of add-ons to supplement its core functionality. In this guide, we’ll show you how Android Studio breakpoints work and how you can maximize their potential in your day-to-day work.

Breakpoints are useful for all kinds of debugging. But for iOS debugging, they’re critical. iOS often veers away from the typical top-to-bottom flow. At the same time, its heavy reliance on async/await can inadvertently lead to concurrency and race conditions. As devs, we need a way to stop the train before it goes too far in the wrong direction. This is what Xcode breakpoints are designed for.

Choosing the wrong date-time API can seriously snarl up your Kotlin app. Timezone mismatches, formatting bugs, inconsistent timestamps – all of them can seriously drain your time and they’re hard to trace without the right tooling. Kotlin gives you multiple date-time tools – LocalDate, Instant, DateTimeFormatter, and kotlinx-datetime – but each is designed for a specific use case across Android, server-side, and multiplatform projects.

Imagine you’re mechanic trying to fix a car. There’s this magic piece of kit that allows you to pause the engine and see inside every moving part. You can tweak parts live, test changes instantly and measure which parts are slowing the whole thing down. This is JavaScript debugging in Chrome. Using Chrome DevTools, you can pause execution, inspect variables and scope, and follow code as it runs. So you can see what the code is actually doing at runtime, without assumptions.

JavaScript dates look simple until they’re not. Here’s the second way to create a date: pass the components manually. Year, month, day, hour, minute—each as a separate number. And anything you skip defaults to zero. So you can write just the year, month, and day like this……but there’s a catch coming.

Learn how to use the JavaScript Date object, format dates correctly, handle timezones, and avoid common bugs with the Date and Time API. This 2025 guide covers parsing, formatting, new date formats, and everything developers need to work reliably with date and time in JavaScript. If you’ve ever seen a date shift by one day, hours changing unexpectedly, or confusing “Invalid Date” errors… this tutorial will finally make it all make sense.

When should you actually use async and await in Swift? Waiting for external data (like APIs or images) Long-running tasks (saving, processing, or calculations) Learn how to use them without freezing your app again.

By Bugfender
Async runs long tasks in the background. Await pauses just one line until the result’s ready. Here’s the cleanest way to understand Swift’s async/await in under a minute — with real examples.

By Bugfender
In this video, we’ll cover async and await, real syntax examples, and the biggest mistakes developers still make. Not just theory — real examples built and tested in Xcode.

Bugfender is a modern remote logger tailor-made for mobile development.
Most developers debug their apps by looking at the logs generated by their application. Usually this means connecting the mobile device with a debugging cable and looking into NSLogs or logcat.
Bugfender is a cloud storage service with an easy to use SDK that lets developers send their application logs for later use. Works for early development phases, beta testing and production applications. Bugfender unlocks the possibility to detect errors earlier, assist better users who contact your customer support and ultimately achieve an excellent customer satisfaction.
Bugfender represents a new opportunity, log collection services have existed for years on the back-end and network monitoring industry but never applied yet to mobile devices.
