Traditionally, connecting devices for peer-to-peer communications has been a tedious task: An application needs to discover what’s around it, open connections on both sides, and then maintain them as network infrastructure, connections, distances, etc. Realizing the difficulties inherent in these activities, in iOS 7 and macOS 10.10 Apple introduced its MultipeerConnectivity framework.

Join Toptal Freelance iOS Developer Ben Gottlieb as he explains what MultipeerConnectivity is, and teaches us how to use it.

Hybrid mobile apps may have their limitations, but often it’s well worth the boost in cross-platform consistency and development speed. Apps made with Apache Cordova in particular can further leverage existing web developer skills through the use of Cordova frameworks. This tutorial compares Ionic with Framework7.

Continuous integration using nothing but Apple tools used to be tedious and time-consuming. This changed with the launch of Xcode 9.0 last September.

In this article, Toptal iOS Developer Nemanja Stosic explains how you can harness the potential of new Xcode features to streamline iOS development.

Despite initial skepticism, React Native is very much in demand today!

In this article, Toptal Freelance React Native Developer, and former React Native skeptic, Alexander Pataridze talks about why he became a React Native advocate instead and introduces us to the technology by illustrating four use-cases.

Many businesses use SharePoint but use it poorly. Restructuring and re-education are the keys to getting the most out of SharePoint. In this article, Toptal Freelance SharePoint Developer Anthony Lucidi explores how features like metadata tags, SharePoint workflows, and PowerApps can make a world of difference.

JSON web tokens (JWTs) provide a method of authenticating requests that’s convenient, compact, and secure. More often than not, Angular apps will include them in their data flows.

In this tutorial, Toptal Freelance Software Engineer Sebastian Schocke shows how to implement JWT authentication in an Angular 6 single-page application (SPA), complete with a Node.js back-end.

The modern, cross-platform programming language Haxe is well-known in some circles, yet many developers have never heard of it. Since it first appeared in 2005, it’s been battle-tested by its loyal—if rather quiet—following.

In this article, Toptal Freelance Software Engineer Kevin Bloch explores the Haxe ecosystem and how to transpile some sample code.

Despite its age, HTTP Live Streaming (HLS) remains a widely used standard in adaptive bitrate video and a de-facto Apple alternative to MPEG-DASH.

In this tutorial, Toptal Java Developer Tomo Krajina explains what makes HLS tick and demonstrates how to create an HLS player in Android.

The development of cross-platform mobile applications has always been a source of many challenges. Although tools like Apache Cordova and Haxe do solve some of the associated issues, they are still not the ideal solution in many cases. React Native changes that by providing the power of React.js for mobile platforms and a promise of consistent developer experience across multiple platforms.

Mobile applications are creeping in. Developing for each mobile platform can be an exhaustive task, especially if resources are limited. This is where Apache Cordova comes in handy by providing a way to develop mobile applications using standard web technologies - HTML5, CSS3 and JavaScript. This article explores how one can get started with Apache Cordova and build mobile applications targeted at a wide range of mobile devices.

Online users are becoming increasingly resistant to traditional email/password registration processes. One-click social logins via Facebook, Google, or GitHub are better, but they come with data privacy trade-offs.

This article introduces a one-click, cryptographically-secure login flow using MetaMask, with all data stored on the app’s own back-end.

In this article, Toptal Freelance Software Engineer Piotr Gaczkowski explains how to make the most out of command line tools and lists some of the best tools out there.

The AI revolution is transforming the consumer world. Some developers may shy away from AI, which has traditionally been a heavily technical specialty. In this article, Toptal Freelance Salesforce Developer Fahad Munawar Khan explores how accessible to developers the AI cloud has become, even for non-Salesforce apps, with Salesforce Einstein.

Working on an iOS application can be tedious, especially when you are wasting countless hours doing the most boring tasks: taking screenshots, signing code, and jumping through similar hoops to get your app to the users’ devices.

In this article, Toptal Freelance iOS Developer Francisco Reynolds walks you through the ultimate release automation tool for your iOS app and shows how it can save you from all of the tedious tasks.

In this article, Toptal Freelance Software Engineer Konrad Gadzinowski dissects trunk-based development and Git flow, listing the pros and cons for various use cases.

In this article, Toptal Freelance Developer Roman Stetsenko explains what it takes to create a pixel-perfect iOS interface from the ground up and why it matters.
