A fast and flexible O(n) difference algorithm framework for Swift collection. The algorithm is optimized based on the Paul Heckel’s algorithm. This is a diffing algorithm developed for Carbon, works stand alone. The algorithm optimized based on the Paul Heckel’s algorithm. See also his paper A technique for isolating differences between files released in 1978. It allows all kind of diffs to be calculated in linear time O(n). RxDataSources and IGListKit are also implemented based on his algorithm. The type of the element that to take diffs must be conform to the Differentiable protocol. Fastest O(n) diffing algorithm optimized for Swift collectionCalculate diffs for batch updates of list UI in UIKit, AppKit and TextureSupports both linear and sectioned collection even if contains duplicatesSupports all kind of diffs for animated UI batch updatesRequires Swift 4.2+Requires watchOS 2.0+

KeychainAccess is a simple Swift wrapper for Keychain that works on iOS and OS X. Makes using Keychain APIs extremely easy and much more palatable to use in Swift. If you want to store the Touch ID protected Keychain item, specify accessibility and authenticationPolicy attributes. Do not run in the main thread if there is a possibility that the item you are trying to add already exists, and protected. Because updating protected items requires authentication. Additionally, you want to show custom authentication prompt message when updating, specify an authenticationPrompt attribute. If the item not protected, the authenticationPrompt parameter just be ignored. The same way as when you get a normal item. It will be displayed automatically Touch ID or passcode authentication If the item you try to get is protected. The same way as when you remove a normal item. There is no way to show Touch ID or passcode authentication when removing Keychain items. Simple interfaceSupport access groupSupport accessibilitySupport TouchID and Keychain integration (iOS 8+)watchOS and tvOS are supportedWorks on both iOS & macOS

Download the Kickstarter app to discover new projects and help put daring ideas into the world no matter where you are. Kickstarter campaigns make ideas into reality. It’s where creators share new visions for creative work with the communities that will come together to fund them. We intend for this project to be an educational resource, we are excited to share our wins, mistakes, and methodology of iOS development as we work in the open. Our primary focus is to continue improving the app for our users in line with our roadmap. No matter what, creators always control how the work comes together, no 100-page grant applications, no donors demanding you modify your message, no last-minute edits from investors. When backers chip in funding and help spread the word, they too become part of these independent works. Run all tests from the command line by running make test-allWe use view models as a lightweight way to isolate side effects and embrace a functional coreThe Screenshots directory holds nearly 500 screenshots of various screens in every languageRun an individual scheme's tests by selecting that scheme in Xcode and hitting CMD+UWe focus on writing well-tested code built with parts that can be easily understood on their ownWe use Swift Playgrounds for iterative development and styling

Kingfisher is a powerful, pure-Swift library for downloading and caching images from the web. It provides you a chance to use a pure-Swift way to work with remote images in your next app. Asynchronous image downloading and caching. Loading image from either URLSession-based networking or local provided data. Useful image processors and filters provided. Multiple-layer hybrid cache for both memory and disk. Fine control on cache behavior. Customizable expiration date and size limit. Cancelable downloading and auto-reusing previous downloaded content to improve performance. Independent components. Use the downloader, caching system, and image processors separately as you need. Prefetching images and showing them from the cache to boost your app. View extensions for UIImageView, NSImageView, NSButton and UIButton to directly set an image from a URL. Built-in transition animation when setting images. Customizable placeholder and indicator while loading images.
