JVFloatLabeledTextField
UITextField subclass with floating labels
JVFloatLabeledTextField is the first implementation of a UX pattern that has come to be known the "Float Label Pattern". Due to space constraints on mobile devices, it is common to rely solely on placeholders as a means to label fields. This presents a UX problem, in that, once the user begins to fill out a form, no labels are present. This UI component library, which includes both a UITextField and UITextView subclass, aims to improve the user experience by having placeholders transition into floating labels that hover above the fields after they are populated with text. The component is officially supported for iOS 9 and greater. If you're a framework author and use JVFloatLabeledTextField as a dependency, update your Package.swift file: -

KeyboardLayoutGuide
KeyboardLayoutGuide, back from when it didn't exist
KeyboardLayoutGuide, back from when it didn't exist. Simply constrain your views to the KeyboardLayoutGuide's top anchor the way you would do it natively. If you add your view in Interface Builder, don't forget to enable the "Remove at build time" checkbox for the bottom constraint. By default, KeyboardLayoutGuide will align your item with the bottom safe area. This is a behaviour that can be opt out by using keyboardLayoutGuideNoSafeArea instead of keyboardLayoutGuide. -

KolodaView
Simplify the implementation of Tinder-like cards on iOS
KolodaView is a class designed to simplify the implementation of Tinder-like cards on iOS. It adds convenient functionality such as a UITableView-style dataSource/delegate interface for loading views dynamically, and efficient view loading, unloading. KolodaView is subclassed from UIView and - as with all UIKit components, it should only be accessed from the main thread. You may wish to use threads for loading or updating KolodaView contents or items, but always ensure that once your content has loaded, you switch back to the main thread before updating the KolodaView. To install manually the KolodaView class in an app, just drag the KolodaView, DraggableCardView, OverlayView class files (demo files and assets are not needed) into your project. Also you need to install facebook-pop. Or add bridging header if you are using CocoaPods. -

When you use blocks and if you need to use self inside it, then you need to make weak reference to self to avoid retain cycle. -

Litho
A declarative framework for building efficient UIs on Android
Litho uses a declarative API to define UI components. You simply describe the layout for your UI based on a set of immutable inputs and the framework takes care of the rest. With code generation, Litho can perform optimisations for your UI under the hood, while keeping your code simple and easy to maintain. Litho can measure and layout your UI ahead of time without blocking the UI thread. By decoupling its layout system from the traditional Android View system, Litho can drop the UI thread constraint imposed by Android. Litho uses Yoga for layout and automatically reduces the number of ViewGroups that your UI contains. This, in addition to Litho's text optimizations, allows for much smaller view hierarchies and improves both memory and scroll performance. -

Loki
Visual Regression Testing for Storybook
There are a few visual regression tools for the web, but most either cannot be run headless or use phantomjs which is deprecated and a browser nobody is actually using. They usually also require you to maintain fixtures. With react-native it's now possible to target multiple platforms with a single code base, but there's no single tool to test all to my knowledge. Loki aims to have easy setup, no to low maintenance cost, reproducible tests independent of which OS they are run on, runnable on CI, and support all platforms storybook does. -

A progress bar for UINavigationBar that works like Apple's Messages app. It also has the added feature of having an indeterminate style. A HUD overlay that works over any UIView. Uses the M13ProgressView class to allow easy customizability of the progress view. A progress view that is styled like a terminal. Complete documentation of each class. Adds a progress bar to the UINavigationController's UINavigationBar. The progress bar is controlled through the UINavigationController. A customizable HUD that displays progress, and status information to the user. It uses the M13ProgressView class to allow easy changing of the progress view style. -

MBProgressHUD
MBProgressHUD + Customizations
MBProgressHUD is a drop-in Objective-C class for iOS that displays a translucent HUD with a spinner, labels, or progress bars during background operations, serving as a polished substitute for private UIKit HUDs. MBProgressHUD works on iOS 9.0+. It depends on the following Apple frameworks, which should already be included with most Xcode templates. The main guideline you need to follow when dealing with MBProgressHUD while running long-running tasks is keeping the main thread work-free, so the UI can be updated promptly. The recommended way of using MBProgressHUD is therefore to set it up on the main thread and then spinning the task, that you want to perform, off onto a new thread. -

MGSwipeTableCell
An easy to use UITableViewCell subclass to display swippable buttons
MGSwipeTableCell provides highly customizable swipe actions for UITableViewCell, emphasizing animated transitions and “expansion” behaviors. You can attach multiple buttons per side, choose from transitions like drag, clip, or 3D-style reveals, and control thresholds for triggering an action on full swipe. The API separates visual configuration (colors, icons, button width) from behavior (callbacks, expansion settings) to keep code readable. It integrates cleanly with table view reuse, ensures state resets during scrolling, and offers convenience helpers for common patterns such as destructive actions. Gesture handling is tuned to avoid interference with vertical scrolling and to coordinate with other recognizers. For teams wanting polished, Mail-like or custom swipe UX beyond system defaults, MGSwipeTableCell is a flexible, production-tested option. -

MMDrawerController
A lightweight, easy to use, side drawer navigation controller
#Mutual Mobile Drawer Controller MMDrawerController is a side drawer navigation container view controller designed to support the growing number of applications that leverage the side drawer paradigm. This library is designed to exclusively support side drawer navigation in a light-weight, focused approach while exposing the ability to provide custom animations for presenting and dismissing the drawer. Starting with version 0.3.0, you can now provide a callback block to determine if a gesture should be recognized using the setGestureShouldRecognizeTouchBlock: method. This method provides three parameters - the drawer controller, the gesture, and the touch. As a developer, you are responsible for inspecting those elements and determining if the gesture should be recognized or not. -

Maestro
Painless Mobile UI Automation
Maestro is the simplest and most effective mobile UI testing framework. Maestro is built on learnings from its predecessors (Appium, Espresso, UIAutomator, XCTest) and allows you to easily define and test your Flows. Built-in tolerance to flakiness. UI elements will not always be where you expect them, screen tap will not always go through, etc. Maestro embraces the instability of mobile applications and devices and tries to counter it. Built-in tolerance to delays. No need to pepper your tests with sleep() calls. Maestro knows that it might take time to load the content (i.e. over the network) and automatically waits for it (but no longer than required). Blazingly fast iteration. Tests are interpreted, no need to compile anything. Maestro is able to continuously monitor your test files and rerun them as they change.
