iOS developers appreciate the open-source libraries available on the platform. Wondering why? These advanced iOS libraries enable them to construct robust iPhone applications effortlessly, ultimately saving considerable time.

These libraries come pre-packaged, allowing developers to utilize them directly in iPhone app development rather than starting from scratch. This approach enables developers to allocate more time to crafting unique features and functionalities for their applications.

By leveraging iOS libraries, developers can enhance their app’s time-to-market by efficiently meeting all milestones. 21Twelve boasts proven expertise in crafting iPhone apps for various industry sectors.

In this context, we’ve outlined the ten most promising iOS app development libraries that facilitate seamless iPhone app development. Incorporate them into your iPhone apps to expedite the development process.

Top 10 iOS Libraries to Speed Up the iOS App Development

1. AFNetworkin

It is the premier iOS library, aiding developers in networking and seamlessly integrating APIs. AFNetworking stands out as an open-source, lightweight, and rapid networking library employing Grand Central Dispatch and blocks.

In essence, it assists developers in streamlining code with superior performance primitives, enhancing app responsiveness, and facilitating a more straightforward concurrency model. AFNetworking finds utility across macOS, iOS, Watch OS, and TV OS.

This library caters to a spectrum of networking needs, ranging from fundamental to advanced, encompassing SSL pinning and network reachability. It boasts resilient APIs that proficiently manage high-level networking abstractions.

2. Alamofire

Alamofire, constructed upon NSURLSession, serves as a paramount HTTP library for streamlining networking within iOS applications. Despite the emergence of various alternatives, Alamofire, rooted in Swift, continues to stand as the preferred choice among iOS developers.

By leveraging the utility methods within the library, developers can proficiently manage diverse networking requests, crafting a networking interface native to Swift. Furthermore, it streamlines numerous networking tasks, encompassing effortless handling of uploads, downloads, and JSON retrieval, thus facilitating network communication within multiplayer games.

Distinguishing features of this library entail the ability to pause and resume networking operations as needed, alongside the provision of subclassable private storage, enhancing the development experience for iPhone applications utilizing Swift.

3. SDWebImage

AFNetworking stands out as a rapid, open-source library enabling seamless web image loading through AFNetworking and UIImageView. However, an alternative library, SDWebImage, serves as an asynchronous image downloader with cache functionality.

This library stores decoded, original, and compressed image files on disk while caching UIImage in memory. Consequently, it aids in optimizing iPhone memory usage by providing sophisticated iOS image management.

4. SnapKit

SnapKit is an iOS library widely known for simplifying AutoLayout creation and setup. Developed in Swift, it streamlines iPhone app development, reducing code quantity compared to conventional approaches. Consequently, apps boast cleaner codebases, enhancing manageability and reviewability. Its secure design aids developers in error reduction and mitigates invalid concerns.

5. MBProgressHUD

It is the ultimate library that caters to all image-related needs not met by other image libraries. MBProgressHUD provides iOS developers with a class enabling them to display a translucent Heads-Up Display (HUD) over images containing text. Additionally, it includes labels and progress indicators during image loading.

Consequently, when an iOS app experiences prolonged image loading or task execution times, the translucent indicators of MBProgressHUD alleviate user anxiety, thus preventing app abandonment.

6. CocoaLumberjack

CocoaLumberjack provides a comprehensive solution for all logging requirements. It stands out as a robust library with superior capabilities compared to basic print or NSLog functions. With features like grand central dispatch, lockless atomic operations, and multi-threading, it offers powerful functionality.

The library boasts ease of use and superior speed over NSLog, allowing developers to create functions with minimal code. It facilitates logging to both file and console simultaneously, sending one log statement to multiple loggers. Due to its adaptability and user-friendly design, CocoaLumberjack is widely favored for enterprise-level logging solutions in iPhone or Mac applications.

7. Kingfisher

It is a library built in Swift for efficiently caching and downloading images. Kingfisher enhances user experience within your application by managing the downloaded images in both disk and memory. The library offers remarkable features like cancellable downloading of independent components, which significantly improves the performance and speed of your application.

Kingfisher effectively caches images for quick display to users, optimizing the user experience. Additionally, there are extensions available for UIButton, NSImage, and UIImageView, facilitating the direct setting of images from URLs.

8. SwiftyJSON

The library’s name itself implies its function in assisting engineers with JSON data in Swift. SwiftyJSON is a simplified, open-source library available for free. It streamlines the process by eliminating the need for optional chaining, a common source of confusion for programmers.

Many developers encounter such challenges, but SwiftyJSON offers a seamless solution that simplifies what was once perceived as complex. By integrating this library, developers can avoid recurring errors, thereby enhancing their productivity and efficiency in coding.

9. Eureka

Eureka stands out as the premier iOS library for Swift, functioning seamlessly as a form builder. Widely employed in applications reliant on forms, Eureka streamlines the form creation process, saving programmers considerable time and effort typically expended on repetitive and intricate coding tasks.

By enabling the creation of highly dynamic forms using reusable code, Eureka eliminates the need for developers to write code for each form iteration repeatedly. This approach fosters efficiency, allowing developers to write code once and deploy it across various contexts.

Furthermore, Eureka’s abstraction capabilities facilitate code duplication and validation, enhancing overall development integrity. Bolstered by a robust developer community, Eureka remains consistently updated, solidifying its status as the premier iOS library.

10. JSONModel

The majority of iPhone applications operate through internet connectivity, engaging with remote servers to exchange data periodically. Some apps necessitate minimal data usage, while others extensively communicate with remote servers.

Presently, all applications utilize JSON for communication with remote servers. In this aspect, JSONModel assumes significance. This open-source library not only validates JSON data but also aids developers in retrieving JSON from servers, parsing it, and initializing model classes with the JSON responses.

The primary function of JSONModel is to present data in JSON format upon receiving requests from the API server. It proves to be a time-efficient tool for programmers, mainly when dealing with intricate data models.


Within the mobile app development process, frameworks play a pivotal role. The Top 10 iOS libraries mentioned above currently dominate the scene and are poised to continue doing so.
