Open Source Objective C User Interface (UI) Software

CamelBones is a Cocoa/Perl bridge for Mac OS X. It allows easy access to the Cocoa API for Perl developers. It also allows easy, object-oriented access to an embedded Perl interpreter for Objective-C developers.

EarlGrey is a native iOS UI automation test framework that enables you to write clear, concise tests. With the EarlGrey framework, you have access to enhanced synchronization features. EarlGrey automatically synchronizes with the UI, network requests, and various queues; but still allows you to manually implement customized timings, if needed. EarlGrey’s synchronization features help to ensure that the UI is in a steady state before actions are performed. This greatly increases test stability and makes tests highly repeatable. EarlGrey works in conjunction with the XCTest framework and integrates with Xcode’s Test Navigator so you can run tests directly from Xcode or the command line (using xcodebuild). To prioritize and improve EarlGrey, the framework collects usage data and uploads it to Google Analytics. More specifically, the framework collects the MD5 hash of Bundle ID, Test Class Names and Test Method Names.

This is an Objective-C wrapper around SQLite. FMDB 2.7 attempts to support a more natural interface. This represents a fairly significant change for Swift developers (audited for nullability; shifted to properties in external interfaces where possible rather than methods; etc.). For Objective-C developers, this should be a fairly seamless transition (unless you were using the ivars that were previously exposed in the public interface, which you shouldn't have been doing, anyway!). FMDB 2.7 is largely the same as prior versions, but has been audited for nullability. For Objective-C users, this simply means that if you perform a static analysis of your FMDB-based project, you may receive more meaningful warnings as you review your project, but there are likely to be few, if any, changes necessary in your code. For Swift users, this nullability audit results in changes that are not entirely backward compatible with FMDB 2.6, but is a little more Swifty.

The Hub Framework is being phased out at Spotify, and therefore we will not be maintaining it further. Welcome to the Hub Framework - a toolkit for building native, component-driven UIs on iOS. It is designed to enable teams of any size to quickly build, tweak and ship new UI features, in either new or existing apps. It also makes it easy to build backend-driven UIs. Instead of building UIViewControllers that each has hard-wired behaviors for UI in terms of controls, data binding & selection handling - a Hub Framework-powered UI is all about components. Components can be reused and rearranged in any way, and render any model. They each define a rectangle on the screen in which anything can be rendered, making it easy to quickly iterate on UI and create modular building blocks that reduce the need for code duplication.

Collection of modularized frameworks, that provide extra encryption, enumeration, and user interface classes on top of Mac OS X's Cocoa frameworks. Designed to be used as piecemeal small embeddable frameworks.

MBCalendarKit is a customizable calendar component for iOS, allowing developers to easily add interactive calendar views to their apps. Inspired by Apple’s Calendar app, it provides day, week, and month views with support for events and appointments. The library is designed to be flexible and easily adaptable to different app designs.

MyLayout is a simple and easy objective-c framework for iOS view layout. MyLayout provides some simple functions to build a variety of complex interface. It integrates the functions including Autolayout and SizeClass of iOS, five layout classes of Android, float and flex-box and bootstrap of HTML/CSS. The MyLayout's Swift version are named: TangramKit
