DialogPlus
Advanced dialog solution for android
Simple and advanced dialog solution. Uses normal view as dialog. Provides expandable option, multiple positioning, and built-in options for easy implementation. DialogPlus provides 3 position. Top, dialog will appear at top with animation. Center, dialog will appear in the center with animation. Bottom, dialog will appear at the bottom of the screen with animation. DialogPlus provides 3 content types. ListHolder, items will be shown in a listview. GridHolder, items will be shown in a gridview. ViewHolder, your customized view will be shown in the content. Set an item click listener when list or grid holder is chosen. In that way you can have callbacks when one of your items is clicked. Set a global click listener to you dialog in order to handle all the possible click events. You can then identify the view by using its id and handle the correct behaviour. Only views which has id will trigger this event. -

Difference
Simple way to identify what is different between 2 instances
Better way to identify what's different between 2 instances. Have you ever written tests? Usually they use equality asserts, e.g. XCTAssertEqual, what happens if the objects aren't equal? Xcode throws a wall of text at you. This forces you to manually scan the text and try to figure out exactly what's wrong, what if instead you could just learn which property is different? -

Douya Bean sprouts
A Material Design app for douban.com
The open source Material Design Douban client. Among all people who directly access Douban, the most common and consistent usage is around ratings, comments, discoveries, and discussions around movies, TV, books, records, and events (what we call "items"). We will use the ratings and comments that are synchronized with the website as a starting point and basis to reconstruct the discovery and discussion around personal interests on the mobile phone. Douban is never a single website, and the usage of Douban is naturally different. Douban is used to obtain information, but whether the acquisition of information is based on entries and algorithms, or based on neighbors and people, this issue has probably remained unresolved in the multiple revisions of Douban. Douban Broadcasting has been one of the few Android Design applications in China a few years ago. Actively express the characteristics of Douban, such as broadcasting, neighbors, Douyou, etc. -

ESTabBarController
Swift model for customize UI, badge and adding animation
ESTabBarController is a highly customizable TabBarController component, which is inherited from UITabBarController. In real-world development, we may encounter the situation of customizing the UITabBar. For instance: change font style, add animation, and use bigger items. However, it's hard to do with UITabBarItem. You can download and build the ESTabBarControllerExample project, and you will find more examples to use ESTabBarController, and also more examples to customize UITabBar, -

EarlGrey
iOS UI Automation Test Framework
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. -

EasyTransitions
A simple way to create custom interactive UIViewController transitions
EasyTransitions is a library that helps developers create custom interactive transitions using simple functions defined in a protocol and avoid handling the multiple transitions APIs in UIKit. During a modal transition, we should only manage the view that is being presented today (modalView). We can inject animations on the root controller anyway. The ModalTransitionAnimator is a really straight forward protocol. Just layout the views ready to be animated on the layout function and perform the animations on animate. You can check the AppStoreAnimator for a basic example. -

Epoxy
Android library for building complex screens in a RecyclerView
Epoxy is an Android library for building complex screens in a RecyclerView. Models are automatically generated from custom views or databinding layouts via annotation processing. These models are then used in an EpoxyController to declare what items to show in the RecyclerView. This abstracts the boilerplate of view holders, diffing items and binding payload changes, item types, item ids, span counts, and more, in order to simplify building screens with multiple view types. Additionally, Epoxy adds support for saving view state and automatic diffing of item changes. We developed Epoxy at Airbnb to simplify the process of working with RecyclerViews, and to add the missing functionality we needed. We now use Epoxy for most of the main screens in our app and it has improved our developer experience greatly. If you are using layout resources in Epoxy annotations then for library projects add Butterknife's gradle plugin to your buildscript. -

Epoxy iOS
Epoxy is a suite of declarative UI APIs for building UIKit apps
Epoxy is a suite of declarative UI APIs for building UIKit applications in Swift. Epoxy is inspired and influenced by the wonderful Epoxy framework on Android, as well as other declarative UI frameworks in Swift such as SwiftUI. Epoxy was developed at Airbnb and powers thousands of screens in apps that are shipped to millions of users. It has been developed and refined for years by dozens of contributors. EpoxyCollectionView provides a declarative API for driving the content of a UICollectionView. CollectionViewController is a subclassable UIViewController that lets you easily spin up a UICollectionView-backed view controller with a declarative API. -

Estimote Fleet Management SDK for iOS
Estimote Fleet Management SDK for iOS
This iOS SDK can be used to update the settings of multiple Estimote beacons at once. You no longer need to connect to each beacon individually. Instead, you use Estimote Cloud to queue ‘pending settings’ on your beacons. Then, your iOS app equipped with this SDK can propagate those settings the moment it encounters the beacons. This also means that, once you deploy the beacons, users of your app can propagate the settings by simply being around the beacons. -

FMDB
A Cocoa / Objective-C wrapper around SQLite
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. -

FXBlurView
UIView subclass that replicates the realtime background blur effect
FXBlurView is an iOS view component that renders a live, dynamically blurred version of the content behind it, giving developers a lightweight way to create frosted-glass and translucency effects. It was designed before Apple’s system blur views became widely available, so it focuses on portability and control rather than tying you to a specific iOS version. The view captures the underlying layer hierarchy and applies a configurable blur, optionally with tinting and saturation adjustments, to match many design styles. Because it updates on the fly, it can respond to animations and scrolling, keeping the blur visually coherent as content moves. The implementation emphasizes performance, using caching and adjustable update intervals so you can trade accuracy for speed on older devices. It’s useful anywhere you want depth and hierarchy cues—overlays, modals, toolbars—without manually pre-blurring assets in a graphics editor. -

FastImageCache
iOS library for quickly displaying images while scrolling
Fast Image Cache is an efficient, persistent, and, above all, fast way to store and retrieve images in your iOS application. Part of any good iOS application's user experience is fast, smooth scrolling, and Fast Image Cache helps make this easier. A significant burden on performance for graphics-rich applications like Path is image loading. The traditional method of loading individual images from disk is just too slow, especially while scrolling. Fast Image Cache was created specifically to solve this problem. In order to understand how Fast Image Cache works, it's helpful to understand a typical scenario encountered by many applications that work with images. iOS applications, especially those in the social networking space, often have many images to display at once, such as user photos. The intuitive, traditional approach is to request image data from an API, process the original images to create the desired sizes and styles, and store these processed images on the device. -

FlatUIKit
A collection of awesome flat UI components for iOS
FlatUIKit is a collection of lightweight, “flat design” UI components for iOS that predates and complements Apple’s modern visual style. It supplies drop-in controls—buttons, alerts, segmented controls, switches—and category helpers for colors and typography so interfaces look clean and consistent. The emphasis is on simple shapes, solid fills, and crisp edges rather than skeuomorphic textures, making it easy to theme entire apps with a few palette choices. Because it’s built as UIKit subclasses and categories, integration is straightforward: you can adopt pieces incrementally without rewriting existing screens. The components are tuned for sensible defaults while leaving room for customization through appearance proxies and property setters. Teams reach for FlatUIKit when they want quick visual cohesion and a modern aesthetic without bringing in a heavy design system. -

FlexLayout
Swift interface to the optimized facebook/yoga flexbox implementation
FlexLayout adds a nice Swift interface to the highly optimized Yoga flexbox implementation. Concise, intuitive & chainable syntax. Flexbox is an incredible improvement over UIStackView. It is simpler to use, much more versatile and amazingly performant. FlexLayout is a companion of PinLayout. They share a similar syntax and method names. PinLayout is a layout framework greatly inspired by CSS absolute positioning, it is particularly useful for greater fine control and animations. It gives you full control by layouting one view at a time (simple to code and debug). -

FloatingPanel
A clean and easy-to-use floating panel UI component for iOS
FloatingPanel is a simple and easy-to-use UI component for a new interface introduced in Apple Maps, Shortcuts and Stocks app. The new interface displays the related contents and utilities in parallel as a user wants. 4 positioning support(top, left, bottom, right). 1 or more magnetic anchors(full, half, tip and more). Layout support for all trait environments(i.e. Landscape orientation). Common UI elements: surface, backdrop and grabber handle. Free from common issues of Auto Layout and gesture handling. FloatingPanel is written in Swift 5.0+. Compatible with iOS 11.0+. The deployment is still iOS 10, but it is recommended to use this library on iOS 11+. If you need more control over showing and hiding the floating panel, you can forgo the addPanel and removePanelFromParent methods. These methods are a convenience wrapper for FloatingPanel's show and hide methods along with some required setup. -

Flutter Go
Demos and documentation for over 140 Flutter UI components
flutter-go is a community-driven Flutter application that serves as an interactive catalog of Flutter widgets, layouts, and patterns. It organizes the Flutter ecosystem into browsable categories—basic widgets, material components, Cupertino elements, layout primitives, and animation demos—so learners can see how pieces behave in a running app. Each entry typically includes a live example, code snippet, and brief notes on properties or usage, turning the app into a hands-on reference you can run on your phone. The project targets newcomers and teams evaluating Flutter by shortening the path from documentation to tangible UI behavior. Because it’s itself a Flutter app, it demonstrates real project structure, navigation, state handling, and theming in practice. The result is a practical companion for discovery and prototyping, helping developers move from curiosity to confident implementation more quickly. -
