    Nimble

    Nimble

    A Matcher Framework for Swift and Objective-C

    Use Nimble to express the expected outcomes of Swift or Objective-C expressions. Inspired by Cedar. Apple's Xcode includes the XCTest framework, which provides assertion macros to test whether code behaves properly. XCTest assertions have a couple of drawbacks. Not enough macros. There's no easy way to assert that a string contains a particular substring, or that a number is less than or equal to another. It's hard to write asynchronous tests. XCTest forces you to write a lot of boilerplate code. Nimble addresses these concerns. Would you like to add more information to the test's failure messages? Use the description optional argument to add your own text. Nimble makes sure you don't compare two types that don't match. Tired of so much typing? With Nimble, you can use overloaded operators like == for equivalence, or > for comparisons.

    ORSSerialPort

    ORSSerialPort

    Serial port library for Objective-C and Swift macOS apps

    ORSSerialPort is an easy-to-use Objective-C serial port library for macOS. It is useful for programmers writing Objective-C or Swift Mac apps that communicate with external devices through a serial port (most commonly RS-232). You can use ORSSerialPort to write apps that connect to Arduino projects, robots, data acquisition devices, ham radios, and all kinds of other devices. Using ORSSerialPort to open a port and send data can be very simple. ORSSerialPort is released under an MIT license, meaning you're free to use it in both closed and open-source projects. However, even in a closed-source project, you must include a publicly-accessible copy of ORSSerialPort's copyright notice, which you can find in the LICENSE file. There are a number of ways to add ORSSerialPort to your project. You can use the included framework project, Carthage, CocoaPods, or the Swift Package Manager. See the Guide to Installing ORSSerialPort for detailed instructions for each of these methods.

    KIF

    KIF

    An iOS functional testing framework

    KIF, which stands for Keep It Functional, is an iOS integration test framework. It allows for easy automation of iOS apps by leveraging the accessibility attributes that the OS makes available for those with visual disabilities. KIF builds and performs the tests using a standard XCTest testing target. Testing is conducted synchronously in the main thread (running the run loop to force the passage of time) allowing for more complex logic and composition. This also allows KIF to take advantage of the Xcode Test Navigator, command line build tools, and Bot test reports. KIF uses undocumented Apple APIs. This is true of most iOS testing frameworks, and is safe for testing purposes, but it's important that KIF does not make it into production code, as it will get your app submission denied by Apple. Follow the instructions below to ensure that KIF is configured correctly for your project.

    Mantle

    Mantle

    Model framework for Cocoa and Cocoa Touch

    Mantle makes it easy to write a simple model layer for your Cocoa or Cocoa Touch application. Core Data solves certain problems very well. If you need to execute complex queries across your data, handle a huge object graph with lots of relationships, or support undo and redo, Core Data is an excellent fit. If you're just trying to access some JSON objects, Core Data can be a lot of work for little gain. Nonetheless, if you're using or want to use Core Data in your app already, Mantle can still be a convenient translation layer between the API and your managed model objects. In order to serialize your model objects from or into JSON, you need to implement <MTLJSONSerializing> in your MTLModel subclass. Mantle doesn't automatically persist your objects for you. However, MTLModel does conform to <NSCoding>, so model objects can be archived to disk using NSKeyedArchiver.

    Promises

    Promises

    Promises is a modern framework that provides synchronization

    Promises is a modern framework that provides a synchronization construct for Objective-C and Swift to facilitate writing asynchronous code. Typically, async operations take a completion handler in a form of a block, which is called to provide either a result or an error. To perform more than one async operation, you have to nest the second one inside the completion block of the first one, and also handle an error gracefully. Often such nesting becomes painful to follow or modify. The framework has intuitive APIs that are well documented making it painless to integrate into new or existing code. Supports both Objective-C and Swift. Promises that are created in Objective-C can be used in Swift and vice versa. Has minimum overhead that achieves similar performance to GCD and completion handlers.

    Chameleon

    Chameleon

    Color framework for Swift and Objective-C

    Chameleon is a lightweight, yet powerful, color framework for iOS (Objective-C & Swift). It is built on the idea that software applications should function effortlessly while simultaneously maintaining their beautiful interfaces. With Chameleon, you can easily stop tinkering with RGB values, wasting hours figuring out the right color combinations to use in your app, and worrying about whether your text will be readable on the various background colors of your app. With a plethora of color choices available for text, it's difficult to choose one that all users will appreciate and be able to read. Whether you're in doubt of your text and tint color choices, or afraid to let users customize their profile colors because it may disturb the legibility or usability of the app, you no longer have to worry. With Chameleon, you can ensure that all text stands out independent of the background color.

    EZAudio

    EZAudio

    An iOS and macOS audio visualization framework

    An iOS and macOS audio visualization framework built upon Core Audio useful for anyone doing real-time, low-latency audio processing and visualizations. I've designed six audio components and two interface components to allow you to immediately get your hands dirty recording, playing, and visualizing audio data. These components simply plug into each other and build on top of the high-performance, low-latency AudioUnits API and give you an easy to use API written in Objective-C instead of pure C. EZAudio was designed to work transparently across all iOS and OSX devices. This means one universal API whether you're building for Mac or iOS. For instance, under the hood an EZAudioPlot knows that it will subclass a UIView for iOS or an NSView for OSX and the EZMicrophone knows to build on top of the RemoteIO AudioUnit for iOS, but defaults to the system defaults for input and output for OSX.

    IGListKit

    IGListKit

    A data-driven UICollectionView framework for building fast lists

    IGListKit uses an algorithm adapted from a paper titled A technique for isolating differences between files by Paul Heckel. This algorithm uses a technique known as the longest common subsequence to find a minimal diff between collections in linear time O(n). It finds all inserts, deletes, updates, and moves between arrays of data. A working range is a range of section controllers who aren’t yet visible, but are near the screen. Section controllers are notified of their entrance and exit to this range. This concept lets your section controllers prepare content before they come on screen (e.g. download images). With the IGListDiffable plugin for remodel by facebook, you can automatically generate models conforming to the IGListDiffable. Remember that IGListKit functions on one model per section controller. You want to create a Post model that contains all of the information that the cells require.

    JazzHands

    JazzHands

    A simple keyframe-based animation framework for UIKit

    Jazz Hands is a simple keyframe-based animation framework for UIKit. Animations can be controlled via gestures, scroll views, KVO, or ReactiveCocoa. Jazz Hands is used extensively in IF and DO by IFTTT for iPhone and iPad, most famously in the app intro. Open JazzHandsDemo.xcworkspace to see a simple demonstration of moving, scaling, fading, and transforming views in a scrolling app intro. To run the example project, clone the repo, and run pod install from the Example directory. Looking to incorporate Jazz Hands into your Swift project? Check out RazzleDazzle, our brand new scrolling keyframe animations library reimagined in Swift. As a bonus, because it's built on top of the animations library, you can even tell JazzHands that you'd like one of your views to show up on multiple pages while other views scroll past, with a single call to keepView:onPages. To see the new JazzHands 2.0 AutoLayout magic in action, check out the example project.

    MetalPetal

    MetalPetal

    A GPU accelerated image and video processing framework built on Metal

    MetalPetal is an image processing framework based on Metal designed to provide real-time processing for still images and video with easy-to-use programming interfaces. This chapter covers the key concepts of MetalPetal, and will help you to get a better understanding of its design, implementation, performance implications, and best practices. A MTIImage object is a representation of an image to be processed or produced. It does directly represent image bitmap data instead it has all the information necessary to produce an image or more precisely a MTLTexture. It consists of two parts, a recipe of how to produce the texture (MTIImagePromise) and other information such as how a context caches the image (cachePolicy), and how the texture should be sampled (samplerDescriptor). MetalPetal does a lot of optimizations for you under the hood.

    Onboard

    Onboard

    Framework to create a beautiful and engaging onboarding experience

    Each onboarding experience is comprised of two primary components, the background and the content pages. The background includes the static background image/video, the page control, and the skip button. The content pages are made up of four pieces, an image/icon, title, body, and action button. Create individual pages by creating instances of OnboardingContentViewController. Provide a title, body, image, text for an action button, and within the action block handle whatever you want to do when the users press the button. If you don't want a button, you can leave both the button text and action handler nil. Then create the OnboardingViewController by providing either a background image or a URL to a local video file in your project, and an array of content view controllers you just created. You can then present the view modally and get the onboarding process started!
