A monorepository is a code management and architectural concept whereby you keep all your isolated bits of code in one super repository instead of managing multiple smaller repositories—like a single repository for your website and mobile apps.

In this article, Toptal Freelance Front-end Developer Alexander Noel attempts to gather and explain as much information as possible about how and when to use monorepos.

Keeping your Android codebase maintainable as your codebase grows can be a challenge. In this article, Toptal Freelance Android Developer Abhishek Tyagi shows how to combine MVVM with Clean Architecture—the latter as described by Robert C. Martin—to write decoupled, testable, and maintainable code.

iOS developers love the power of UIKit, and animating a UIView is usually fairly easy. However, if you want to chain animations together and set up dependencies between them, your code can quickly become difficult to read with many nested closures and indentation levels.

In this article, I’ll explore how to apply the power of a reactive framework such as RxSwift to make that code look much cleaner as well as easier to read and follow. My client wanted a story told through a sequence of animations rather than by playing a pre-rendered video, and with RxSwift, we easily tweaked it to perfection.

Code reuse turns lazy developers into efficient geniuses. Imagine if you could write the majority of your code once and run it on the web and native mobile—both iOS and Android.

In this article, Toptal Freelance Dart Developer Marko Perutović introduces us to the BLoC pattern, whereby you can isolate your business logic in pure Dart and reuse it in both Flutter and AngularDart.

The Model-View-Controller (MVC) design pattern is great for the longevity and maintainability of an iOS application’s codebase… but you may find yourself adding similar functions to multiple models as your app grows. In cases such as networking, moving common logic out of your model classes and into singleton helper classes can be a better approach. In this article, I’ll teach you how to set up a centralized singleton networking object that, decoupled from micro-level MVC components, can be reused throughout your application.

With augmented reality on the rise, more and more libraries and tools are developed to tap into that market. Apple recently released ARKit, which shows great promise through power and simplicity of use.

There is no way around application diagnostics. No matter how good your code is, you will need to be able to monitor and study system behavior. This is where Android’s DDMS shines.

In this article, Senior Android Engineer Gilad Haimov explains how veteran Android developers leverage the potential of DDMS to improve app stability and performance, test new features, diagnose, and debug their code.

Writing reusable code that can be shared across multiple platforms can make developing mobile applications a lot easier.

In this tutorial, Toptal Software Engineer Dino Bartošak explains how to implement an MVVM design pattern on a demo Swift application.

Since the inception of the platform, Android developers have had pretty much only one option for a database: SQLite. Although feature-rich and powerful, it wasn’t quite what Android app developers needed. Realm, a modern, efficient database solution for mobile platforms, turned out to be an amazing replacement for SQLite on Android.

In this article, Toptal Software Engineer Mateus Gondim Romão Batista explains why you should use Realm for your next Android application.

In the past few years, Microsoft has pulled a few aces from up its sleeve. Yes, they messed up Skype, failed with smartphones, and almost succeeded with tablets. But, they did some really amazing things as well.

Relinquishing their closed empire approach, they open-sourced .NET, joined the Linux Foundation, released SQL Server for Linux, and created this great new tool called Visual Studio for Mac.

In this post, Head of Open Source Demir Selmanovic details how to make an Android and iOS app in C# on your Mac.

Most modern programming languages, in the hopes of enhanced maintainability and reusability of code, offer some constructs that help the developer keep the definition of behavior and its implementation separate.

Swift takes the idea of interfaces a step further with protocols. With protocols and protocol extensions, Swift allows developers to enforce elaborate conformity rules without compromising the expressiveness of the language.

In this article, Toptal Software Engineer Alexander Gaidukov explores Swift protocols and how protocol-oriented programming can improve the maintainability and reusability of your code.

If you’re a veteran frontender, you’ve probably had some not-so-great experiences with designers, and chances are some designers have had an equally bad experience working with you. How can you make sure you get exactly what you need from your designer, without placing an undue burden on them?

It’s a tall order, but in this article Freelance Software Engineer Vedran Aberle Tokic outlines and addresses a number of potential issues that may become roadblocks for your execution. Implementing these suggestions may result in overhead for designers, but they can save enormous amounts of time and headache elsewhere.

Client-server interactions play a vital role in most modern mobile applications. By leveraging available backend services these mobile applications can provide some really amazing functionalities. However, as mobile applications grow complex it becomes essential to keep the networking module as clean and maintainable as possible - separated from the rest of the application logic.

In this article, Toptal freelance software engineer Alexander Gaidukov walks us through the design of a simple networking module that allows your iOS application to interact with RESTful APIs.

Swift is the new programming language created to be a modern replacement for Objective-C in iOS and OS X application development. In general, a skilled Swift developer is usually someone who is already experienced with Objective-C, and that, among other things, might lead them to write Swift code using Objective-C best practices, which can cause some bad mistakes.

In this article, Toptal Freelance Software Engineer Nilson Souto outlines the most common mistakes Swift developers should be aware of.

Any experienced developer will tell you that their best code isn’t code they wrote. It’s code they took from someone else’s work. Many of the problems we encounter have already been solved—and the remedies packaged into libraries available to anyone. Why reinvent the wheel when free wheels are everywhere?

In this guide, Senior Android Engineer Gilad Haimov will take you on a quick tour of some the most powerful Android libraries out there. Robust as a hammer, faster than a drill, and more precise than any scalpel; no Android developer should leave home without these must-have tools.

Google formally announced Android 7.0 a few weeks ago, but as usual, you’ll have to wait for it. Thanks to the Android update model, most users won’t get their Android 7.0 over-the-air (OTA) updates for months. However, this does not mean developers can afford to ignore Android Nougat.

In this article, Toptal Technical Editor Nermin Hajdarbegovic takes a closer look at Android 7.0, outlining new features and changes. While Android 7.0 is by no means revolutionary, the introduction of a new graphics API, a new JIT compiler, and a range of UI and performance tweaks will undoubtedly unlock more potential and generate a few new possibilities.

Apple’s iOS is the second-largest mobile operating system in the world. It also has a very high adoption rate, with more than 85 percent of users on the latest version.

The plethora of tutorials on building Android apps may have you thinking that making a mobile app is simple. In reality, however, performance issues can be very complicated, and because performance plays a key role in making sure that your app stays on your users’ list of favorite apps for a long time, every little detail must be given one’s full attention.

In this article, Toptal Freelance Software Engineer Tibor Kaputa shares some tips on how you can optimize some common performance issues and identify some of the bottlenecks in your Android app.

Many product owners don’t have a technical background and thus often find themselves unprepared and scrambling when it comes time to bring on a new development team. This often results in hindered progress, wasted time, and frustration for everyone involved. If this sounds like it could be you, either now or in the future, then you should be somewhat concerned.

In this blog post, Toptal Freelance Software Engineer Carlos Ramirez III will walk you through the various steps of a typical transition process in project management so you can prepare for this eventuality and make the transition as smooth as possible.

Ionic is extremely popular at the moment, and it has revolutionized the hybrid application industry in a way that nobody could have imagined. However, over time, the best practices and tooling for Ionic have not progressed in the same way. As a result, the number of pitfalls that developers need to look out for when working with Ionic is still high.

In this article, Toptal Freelance Software Engineer Julien Renaux outlines the most common mistakes that Ionic developers should know.

Navigation in mobile applications, when done right, can have tremendous positive impact on overall user experience. Android offers application developers multiple ways of implementing navigation in their application. However, not all navigation patterns are created equal.

In this article, Toptal engineer Becze Szabolcs shows us how to implement fragment-based navigation and how it stacks up against Android’s traditional navigation philosophy.

Google Cardboard was envisioned as the cheapest Virtual Reality (VR) solution on the planet, and at this point, nothing else comes close in terms of pricing. However, the low price did not bring about mass adoption, and Google’s Android-based VR platform is nothing more than a tech curiosity at this point.

In this post, Toptal Technical Editor Nermin Hajdarbegovic leverages his extensive experience in the graphics industry to explain what’s keeping Cardboard VR down, and what the platform needs to attract more users, investment, and development.

Apple’s iOS 9 and WatchOS 2 updates brings a number of novel features, including improved multitasking for iPads and a host of aesthetic tweaks. However, while iOS 9 is just an incremental update with a focus on the new iPad Pro, WatchOS 2 is not a skin-deep update. Apple has changed the WatchOS architecture and opened up a range of new possibilities for developers.

Several factors conspired to stifle Android Wear growth, ranging from lack of Google development, to inadequate hardware. Some of these problems have been addressed, some are being addressed, while others cannot be addressed with currently available technology.

Force Touch is not a new idea. BlackBerry experimented with the concept back in 2008, and a few Android phone makers also examined the possibility of using Force Touch on their products. In fact, Force Touch support has been a part of Android for years; it was introduced in Android 1.0.

Today, we will be taking a look at the future of mobile payments and emerging opportunities for developers. Needless to say, with each new opportunity, developers will have to face new challenges.

However, since we are talking about money, I don’t think anyone expects a shortage of software developers eager to learn a few new tricks and get into this space.

Cars with next-generation connected infotainment systems will create new opportunities on several fronts. In case you already have an infotainment system with a neat touchscreen and GPS in your car, please accept my condolences; it’s about to become as obsolete as a Nokia 3310 compared to an iPhone.

A large number of modern mobile applications interact with web services in one way or another, and iOS applications are no different. Mantle (a model framework) and Realm (a mobile database) come with the promise of simplifying some of the hurdles in consuming web services through RESTful APIs and persisting data locally. In this article, Toptal engineer Marcin Kmiec shows how to build a simple iOS application using Mantle and Realm and demonstrates how this approach helps to eliminate a large amount of boilerplate code.

OpenGL, a cross-platform API for rendering 2D and 3D graphics, is extremely powerful and yet surprisingly easy to get started with. Although one may find the most common applications of OpenGL and rendered graphics in video games only, in reality there are far more uses. To demonstrate the power of OpenGL, we’ll be building a Mandelbrot set generator on Android using OpenGL ES.

It is not uncommon for developers to find themselves in need of a UI component that is either not provided by the platform they are targeting or is, indeed, provided, but lacks a certain property or behavior. The answer to both scenarios is a custom UI component. The Android UI model is inherently customizable, offering the means to create custom UI components in various ways.

Whether you’re an avid angler or an app developer, you may be interested in taking a closer look at the development of a fishing app, which involved some of your fellow Toptalers.

The goal was to create an app that would be truly useful in a professional fishing setting, while at the same time meeting a hard deadline. Since Fatsack Outdoors wanted to launch the app at one of the biggest fishing tradeshows of the year, the deadline was non-negotiable.

Detecting objects of interest in images has always been an interesting challenge in the realm of computer vision, and many approaches have been developed over recent years.

This article walks us through the process of building a simple iOS application for detecting objects in images.

Google announced Android M at its annual I/O dev conference in late May, and the new OS is coming to our beloved Android devices later this year. Android 6.0 is more of an evolutionary step, whereas Android 5.0 was a big leap forward thanks to its 64-bit ART runtime and all new Material Design.

However, Android M should not be dismissed as a minor update. In this post, I will try to explain why.

With Dalvik out of the picture, many people expected Google’s new 64-bit capable ART runtime to stick around for years, which it probably will, but it will get a major overhaul in the near future. In addition to offering support for 64-bit hardware, ART also introduced ahead-of-time (AOT) compilation, while Dalvik was a just-in-time (JIT) compiler.

Throw in new 10-core ARM processors and Intel mobile processors based on three different architectures, and you end up with spicy, Google-style hardware gumbo.

While the Apple Watch is on track to be a commercial success for Apple and its shareholders, technologists are still not entirely convinced smartwatches have what it takes to conquer the market, at least not yet.

What does this mean for developers? What are the implications for other smartwatch platforms and companies behind them?

iOS 8 introduced a new concept called App Extensions. This new feature did not break down the walls between the applications, but it opened a few doors providing gentle yet tangible contact between some apps.

Passwordless authentication has been the Holy Grail of security for years, but progress has been painfully slow. Until a few years ago, the technology to implement passwordless logins on a grand scale simply wasn’t available.

However, the industry juggernaut is slowly but surely changing this. There are a few technical, legal and even ethical considerations to take into account, but be as it may, biometric, passwordless authentication is here to stay.

Describing Nvidia Shield as a mere Android console would not do it justice. The console relies heavily on streaming and cloud computing, so it shouldn’t not be viewed as another standalone device.

Nvidia sees Shield as Netflix for games, as a comprehensive Gaming-as-a-Service (GaaS) platform. While it’s still part of the Android ecosystem, Shield could be bad news for some Android game developers, but it also creates a range of new and exciting opportunities.

After a couple of years of bullish forecasts and big promises, security seems to be the biggest IoT concern. The first few weeks of 2015 were not kind to this emerging industry, and most of the negative press revolved around security.

Was it justified? Was it just “fear, uncertainty and doubt” (FUD), brought about by years of hype? It was bit of both; although some issues may have been overblown, the problems are very real, indeed.

Microsoft has a long tradition of spicing up relatively dull product announcements with compelling tech demos, and the Windows 10 announcement was no exception. The software giant used the opportunity to create a fair amount of buzz about the HoloLens, a futuristic headset that offers a glimpse into the future of Augmented Reality (AR).

This article provides step by step guide for building hybrid multi-platform real-time mobile application using the Ionic Framework and the Firebase.

Google Glass promises to revolutionize how we use our devices to interact with the world. But from a developer’s standpoint, what is so special about developing for the Glass? You’ll be glad to know that the answer is “Nothing!” Here’s a step-by-step tutorial that walks you through developing your first Google Glass app.

I often hear iOS developers ask some variant of the same key question: “What’s the best way to develop a UI in iOS: through Storyboards, NIBs, or code?”

Answers to this question, explicitly or implicitly, tend to assume that there’s a mutually exclusive choice to be made, one that is often addressed upfront, before development.

I’m of the opinion that there’s no single choice to be made. Rather, each option has its strengths and weaknesses—and there’s no need to use any one of them in isolation.

With the increasingly ubiquitous nature of mobile devices and applications, if you’re not already thinking about mobile apps, you probably should be. This post focuses on methodologies and tools to employ, and pitfalls to avoid, in the development of highly functional, intuitive, and easy-to-use mobile web apps.

Making a basic Android app is easy. But making it reliable, scalable, and robust, on the other hand, can be quite challenging. With thousands of available devices pumped out from tons of different manufacturers, assuming that a single piece of code will work reliably across phones is naive at best. Segmentation is the greatest tradeoff for having an open platform, and we pay the price in the currency of code maintenance, which continues long after the app passes the production stage.

In this post, we’ll walk through a solution: automated crash reporting with ACRA and a Cloudant back-end, all visualizable with acralyzer.

Building games for the iOS platform can be an enriching experience in terms of both financial and personal growth. Recently, I deployed a Cocos2D-based game to the App Store. In this post, I’ll explain the process behind developing games for iOS, from Cocos2D through to publishing.

It’s always fun to put your programming skills on display. A while back, I figured it’d be cool to try and control my laptop via my Android mobile device. Think about it: being able to play and pause music, start and stop programming jobs or downloads, etc., all by sending messages from your phone. Neat, huh?
