In this article we’ll learn about Apple’s MapKit framework. MapKit is the native way to include map views in our iOS application to display map or satellite imagery. It is quite useful for any map-centric view and to show coordinates, annotate on them with a custom annotation, or just generally view world locations or specific map features. This article will be very hands-on and will include several examples on how things are done using MapKit and the mapkit api.

2025, developers use advanced tools and strategies to debug apps running in distributed systems, microservices, and modern frameworks like Flutter, React, and SwiftUI. Here’s a quick summary of the best practices to make remote debugging faster and more secure.

The crash-proof app doesn’t exist. It never has, and it probably never will. Because apps can crash for all kinds of reasons, some of them impossible to foresee. No matter how well we build them, crashes are going to happen to our apps. So, as devs, we need to know how to react to a crash when it happens. And in this context, understanding crash reports is crucial. They provide the clues we need to put the pieces together.

The Android emulator is an Android virtual device that is used to test and debug Android code. It looks and behaves the same as a physical Android device, and while it has some limitations (more of which later), it provides real time and cost savings for developers. Unlike the iPhone, which is limited to one manufacturer and a specific number of iOS versions, there are thousands of Android device types out there.

Imagine you’re a toolmaker. You’ve got an old-school toolshed with loads of ancient equipment: hammers, pickaxes, all the stuff people used hundreds of years ago. And then one day you walk into your toolshed to find laser cutters, 3D printers and loads of other digital tools at your disposal. Life would suddenly seem a lot simpler, right?

Last week, we got a question from one of our users asking us how to use Kotlin Apply. Specifically, the reader wanted to know whether it was best to use the apply function in their Android application, or another of the many Kotlin scope functions. So we got to thinking: Why not write an article about the whole topic of Kotlin scope functions? After all, they’re awesome: they let us write readable, concise code in Kotlin, and work with an object without the need for repeated references.

Concurrency is the ability of an app to perform multiple tasks at once, and it’s a crucial concept for apps that need to perform multiple tasks at once in an efficient, usable way. Thankfully Swift has made great strides with concurrency, and now provides simple tools for writing robust apps that are responsive and enjoyable to use. In this article we’ll explore two main ways of using threads for concurrency models.

Navigation is one of the most basic functionalities of any app, and among the most crucial aspects of our work as developers. From replacing a login screen with our actual logged-in state app, to showing a modal with details of any item inside our app, all of these are navigational challenges we need to tackle in our day-to-day. SwiftUI has introduced a modern approach to navigation in Apple-based platforms.

In Android, ImageView is a widget used to show an image, so it’s vital for every kind of app we build. In fact, it’s the most common widget that we’ll use as Android developers. The image can be a profile image, graphic, or any other type of image, and it can be loaded from a res/drawable folder or an external source. ImageView is pretty straightforward once you’ve got the hang of it, but there’s some stuff we need to know if we’re going to make the most of the widget.

Animations make our apps seem more alive, approachable and interactive, and they add that extra level of polish, which is crucial in an age of ever-greater consumer choice. One of the great things about Swift is that it provides a range of animation functionality straight out of the box. In this post, we’ll explore some of this functionality and demonstrate some popular techniques for SwiftUI animations, so you can use them on your own projects.
