This is the most fertile time for app development since the launch of the App Store 15 years ago.

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. As developers, we need to stay up to date with all the latest libraries and tools—and this is particularly true of iOS, given the advances promised by the latest update.

In this article, we’ll take a look at the essential iOS libraries every dev needs to know right now. From UI frameworks to animation libraries, we’ll show you how to build a UX that will wow even the most cynical of users.

## First, here’s how to unleash the power of dependency managers

As a first step to use any iOS library, you need to add it as a dependency, and dependency managers make the whole process effortless.

There are a number of different dependency managers for iOS, and each has its own pros and cons. But the two most popular, right now, are CocoaPods and Carthage.

**[CocoaPods](https://cocoapods.org/)** is a centralized dependency manager. In other words, it uses a centralized repository to manage libraries. This means that it’s easy to find and add libraries to your project, and you don’t need to worry about building and managing them yourself. Another nifty little bonus is that CocoaPods has a large community and loads of resources available, which is a major value-add in such a fluid, fast-moving environment.

**[Carthage](https://github.com/Carthage/Carthage)**, on the other hand, uses the libraries’ source code and builds them locally. This allows you to use specific commits, branches, or versions of a library, with no centralized repository. This can be particularly useful if you want more creative control over the libraries you use and don’t want to rely on a central authority.

In any case, you can always use both variants in the same project. But remember that the installation for each manager, and the way the libraries are linked, is markedly different.

## Right, let’s look at the iOS libraries you need to know about

[![](https://bugfender.com/wp-content/uploads/2023/01/Untitled-1.jpg)](https://bugfender.com/wp-content/uploads/2023/01/Untitled-1.jpg)

Since Apple first sent Swift live in 2014, the number of libraries has increased at a seemingly exponential rate. From utility libraries that simplify tasks to UI libraries that energize your interfaces, there’s a specialist option for every developer.

Everyone will have their own favourite iOS library, depending on the apps they build and their own personal coding style. But here are 10 that we find particularly useful (in no particular order):

1. **Alamofire** – a powerful networking library for iOS and macOS.
2. **SDWebImage** – a library for downloading and caching images from the web.
3. **SwiftyJSON** – a library for working with JSON data in Swift.
4. **MBProgressHUD** – a library for displaying progress indicators and progress views.
5. **Charts** – a library for creating beautiful charts and graphs on iOS.
6. **Realm** – a mobile database for iOS and Android.
7. **Reachability** : A library for monitoring the network status of an iOS device
8. **ReactiveCocoa** – a framework for functional reactive programming in iOS and macOS.
9. **Masonry** – a library for creating and manipulating constraints in iOS and macOS.
10. **Lottie** – an iOS library that allows developers to easily add animations to their app

And, as a lovely little bonus:

**Bugfender** – Remote Logger, Crash Reporter and In-App User Feedback

Ok, now let’s dive beneath the surface and get deeper into each one. We’ll also give you an alternative for each of our 10 nominees, so you’ve got plenty of options. But remember: this list is by no means exhaustive.

### Almofire

[https://github.com/Alamofire/Alamofire](https://github.com/Alamofire/Alamofire)

Alamofire is an open-source library for iOS and macOS that simplifies the process of working with HTTP and HTTPS network requests.

It is built on top of Apple’s Foundation URL Loading System and provides a more convenient API for working with network requests. On top of those headline characteristics, it provides a bunch of additional features like chainable request/response methods, JSON parameter and response serialization, and authentication.

## Ok, that’s a wrap(p)

We’ve taken into the weeds and discussed various iOS libraries and frameworks, laid out their main features and use cases, and given you alternative options. All of these libraries and frameworks are open-source, actively maintained and widely used by iOS developers, so you can choose the one that best suits your needs and the requirements of your project.

But remember: you should keep updating your knowledge base, because the possibilities are increasing all the time… and so are the potential competitors.
