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.
In this blog post, we dive into the top five developer struggles associated with maintaining self-hosted CI/CD hardware, and present solutions offered by Bitrise.
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.
Learn about the latest updates to our user roles and permissions. This update introduces a revamped permissions structure, shifting control to admins for assigning release manager roles and enhancing overall platform security.
The app size on my phone is 1GB which is double the size of my next largest banking app and 10 times the size of the following two. Does SoFi care to optimize the app? I’m hoping getting rid of the crypto exchange will reduce the overall size.” Said Mizzo12 on Reddit For too long, have we sat silent and allowed our app sizes to grow too big! While some of us enjoy the luxury of 5G internet and what seems like infinite storage, not everyone does! So..
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.
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.
This is the most fertile time for mobile app development since the launch of the App Store. Our industry is in the grip of several simultaneous revolutions, each of them bending, flexing and moulding to the others. 5G promises to make our apps 10 times faster; wearable technology lets them wrap themselves around our bodies; artificial intelligence enables them to learn from us and get smarter every day. But this torrent of innovation brings challenges, too.
Creating a visually captivating, interactive user interface is fundamental to our work as developers. And SwiftUI, Apple’s declarative UI framework, is a game-changer, providing views, controls and layout structures for the iOS, macOS, watchOS and tvOS operating systems. Of all SwiftUI’s many components, SwiftUI buttons stand out as particularly crucial elements for user interaction.
