Pickers are UI elements, provided by SwiftUI, that enable our users to choose between multiple options while using our iOS app. In this article we’ll have a look at them to see the various types and explore how they’re declared, configured, and styled. Together with SwiftUI buttons, pickers are one of the most used UI elements in iOS apps.

Arrays enable you to group and order elements of the same type, so they play a crucial role in organizing your app’s data. If you’re building an iOS app, arrays are a vital part of your toolkit, and today we’re going to help you understand them. Specifically, we will give you a backend view of how Arrays work and jump into a host of specific operations, from simple filtering and sorting to complex ways of mapping and reducing them.

Static sites (websites) are not new. In fact they’ve been around since the era of Web 1.0. Back in those dim and distant days the internet only had a few contributors, so managing and maintaining a static website was fairly hassle-free, they use to have a couple of static html files. However, the needs of creators and consumers have changed dramatically since then. So we need a new technology to generate static sites, befitting the resources and innovative spirit of the digital revolution.

NSLog is a very useful function call that iOS developers are able to utilize, and it is one of the most common development tools used to debug iOS apps. Among other things, NSLog can be used to check the value of variables, log any notes that you need to make, and check for errors when you do not have a debugger available. While NSLog is fairly handy, it is not a universal tool that can solve all of your programming problems.

In iOS, geofencing is a location-based feature that enables us to define geographical boundaries and trigger actions, or alerts, when a device enters or exits those boundaries. This feature has become vital to all kinds of apps, enabling them to deliver personal, timely and contextual experiences.

Unit tests are performed on a single unit of code, usually on a specific function, variable or flow. They allow us to test the components in isolation and validate each single component’s reliability in turn. In this article we’ll introduce the concept of Swift unit testing, and explain, at a high level, why you should carry them out, how you can start developing your iOS apps in a test driven development methodology and how you can write Swift unit test cases.

In the competitive landscape of iOS app development, ensuring the quality and functionality of your application is crucial. That’s where automated testing tools come in, enabling developers to streamline their testing processes and deliver robust, bug-free applications. In this comprehensive overview, we dive into the world of automated testing tools for iOS, exploring the top contenders that can revolutionize your testing efforts.

With its simplicity, flexibility, and cost-efficient characteristics, Amazon Simple Storage Service (Amazon S3) cloud object storage has become the preferred platform for collecting, analyzing, and retaining today’s growing mountain of diverse and disjointed enterprise data. And as Amazon Web Services (AWS) continues to grab market share in the hyperscale IaaS/PaaS/SaaS marketplace, organizations of every size are leveraging Amazon S3 to underpin a variety of use cases, such as.

In Android app development, creating a smooth, responsive user experience is essential. Kotlin coroutines help developers achieve this by streamlining and speeding up the app’s background operations. Kotlin coroutines significantly simplify the way we write asynchronous code and they allow any Android developer to easily run a background task or an asynchronous task.
