Termux Desktop
Setup A Beautiful Desktop/GUI In Termux
Termux Desktop is a collection of dotfiles and scripts for setting up a graphical Linux-style desktop environment inside Termux on Android. It helps users turn a phone or tablet into a more complete desktop-like workspace without needing root access. The setup uses VNC so the desktop can be opened through a VNC client after installation. It includes an Openbox-based environment with visual themes, menus, app launchers, terminal tools, file management, browser access, and system applets. The project is especially useful for experimenting with coding, Linux tools, classic applications, and lightweight desktop workflows on Android hardware. Since the repository is archived and marked as unmaintained, it is best treated as a legacy reference setup rather than an actively supported Termux desktop solution. -

IBPCollectionViewCompositionalLayout
Backport of UICollectionViewCompositionalLayout to earlier iOS 12
IBPCollectionViewCompositionalLayout is a backport of Apple's UICollectionViewCompositionalLayout APIs for older iOS versions. It allows applications targeting iOS 12 to adopt the compositional layout model introduced with iOS 13. Developers can define complex collection views from items, groups, sections, and dimensional rules instead of writing extensive custom layout subclasses. The same approach can create lists, grids, mosaics, nested groups, banners, and independently scrolling sections. An interoperability file helps projects share layout code between systems using the native API and those using the backport. The library closely mirrors Apple's API so migration requires minimal conceptual changes. It was created to reduce duplicate layout code during the transition to newer UIKit versions. -

Popcorn Time for iOS
https://github.com/PopcornTimeTV/PopcornTimeTV
PopcornTimeTV was an Apple TV, iPhone and iPad application to torrent movies and tv shows for streaming. Since 2016, this project has grown exponentially - both in its user base and in its functionality. However, the team size has gone the other way. We went from having 13+ developers on the team to 1 developer and 1 designer, both of whom have lives and projects outside of Popcorn Time. We have decided that we have given our all to this project and it's time for us to move on to pursue greater things. There is no doubt that this comes with a heavy heart as we have learned so much from this project and watched it grow from this simple torrenting app that could only play 720p video, to what it is today. All that being said, we do not want this project to just die after we leave. The size of the project might be a bit daunting to an unseasoned developer but the app is extremely stable and packed with almost every feature you could need. -

Parchment
A paging view with a highly customizable menu
New beta is out! Features a new and improved API for SwiftUI. Try it now. Parchment lets you page between view controllers while showing any type of generic indicator that scrolls along with the content. The menu items are built using UICollectionView, which means you can display pretty much whatever you want. You can even subclass the layout to create completely custom behaviors. Parchment only allocates view controllers when they’re needed, meaning if you have a lot of view controllers you don’t have to initialize them all up-front. Because view controllers are only allocated as you are scrolling, you can create data sources that are infinitely large. This is perfect for things like calendars. -

Sonic iOS
Bridge of iOS Devices by usbmuxd
sonic-ios-bridge is based on gidevice as the underlying iOS communication protocol. On this basis, peripheral auxiliary functions are enriched, such as automatic mounting of developer images, wda installation detection, iOS model mapping, direct use of command lines, etc. To create a command-line iOS debugging tool that executes xctest, WebDriverAgentRunner, performance monitoring and other special functions across platforms. So you can use sib to perform cross-terminal iOS automation, iOS device communication, and iOS device testing without Mac. Whether gidevice or tidevice, the main principle is to communicate with usbmux. The role of usbmux is to realize cross-platform communication with iOS device services. On the Mac, usbmuxd is a service of Apple, which is mainly used to implement TCP connections on the USB protocol. Both iTunes and Xcode use this service, so the Windows system needs to install iTunes. -

Flutter InAppWebView Plugin
A Flutter plugin that allows you to add an inline webview
A Flutter plugin that allows you to add an inline WebView, to use a headless WebView, and to open an in-app browser window. Adding the InAppWebView widget into your app is very simple. It’s just a widget like any other Flutter widget. Use InAppBrowser or ChromeSafariBrowser to open an in-app browser! ChromeSafariBrowser is based on Chrome Custom Tabs on Android and on SFSafariViewController on iOS. Create a Class that extends the InAppBrowser/ChromeSafariBrowser Class in order to override the callbacks to manage the browser events. It can be used to run a WebView in background without attaching an InAppWebView to the widget tree. As InAppWebView, it has the same options and events. Use InAppWebViewController to control the headless WebView instance. -

SwiftTweaks
Tweak your iOS app without recompiling!
Your users won’t see your animation study, Sketch comps, or prototypes. What they will see is the finished product - so it’s really important to make sure that your app feels right on a real device! Animations that look great on your laptop often feel too slow when in-hand. Layouts that looks perfect on a 27-inch display might be too cramped on a 4-inch device. Light gray text may look subtle in Sketch, but it’s downright illegible when you’re outside on a sunny day. These animation timings, font sizes, and color choices are all examples of “magic numbers” - the constants that give your app its usability and identity. The goal of SwiftTweaks: allow you to fine-tune these magic numbers in the debug builds of your Swift project, without having to wait for Xcode to rebuild the app. -

BottomSheet
Android component which presents a dismissible view
BottomSheet is an Android component which presents a dismissible view from the bottom of the screen. BottomSheet can be a useful replacement for dialogs and menus but can hold any view so the use cases are endless. This repository includes the BottomSheet component itself but also includes a set of common view components presented in a bottom sheet. These are located in the commons module. The IntentPickerSheetView component presents an intent chooser in the form of a BottomSheet view. Give it an intent such as a share intent and let the user choose what activity they want to share the intent with in a BottomSheet. The MenuSheetView component presents a BottomSheet view that's backed by a menu. It behaves similarly to the new NavigationView in the Design support library, and is intended to mimic the examples in the Material Design spec. It supports list and grid states, with the former adding further support for separators and subheaders. -
