Kiwix
An offline reader for iOS and macOS that makes Wikipedia and other web content available without an internet connection.
What is Kiwix?
Kiwix for Apple iOS & macOS is an open-source offline reader application that allows users to access web content, especially Wikipedia, without an internet connection. It solves the problem of information accessibility in low-connectivity environments by reading highly compressed ZIM archive files locally on Apple devices.
Users in areas with limited or unreliable internet access, educators, researchers, travelers, and anyone who needs offline access to Wikipedia or other web-based knowledge resources on iOS or macOS devices.
Developers choose Kiwix for its robust support of the open ZIM format, its native performance on Apple platforms, and its commitment to the open-source mission of making knowledge freely accessible to all, regardless of internet availability.

Pros & Cons
Pros
Uses the highly compressed ZIM format, enabling storage of entire Wikipedia or other web content locally with minimal space, as highlighted in the README.
Built as a single codebase for both iOS and macOS, ensuring native performance and consistent updates across Apple devices, supported by App Store deployment.
Leverages XcodeGen for project file generation and Homebrew for automated dependency management, simplifying the build process for developers.
Includes unit tests and UI automated tests for both iOS and macOS, backed by continuous integration workflows to maintain code quality.
Features automated nightly builds to FTP, weekly TestFlight updates, and a clear release process for App Store submission, as detailed in the deployment section.
Cons
Video content in ZIM files only works reliably from Kiwix 3.4.0 and iOS/macOS 17.0/14.0 onwards, with bugs in older versions not being investigated, as noted in the known bugs section.
Requires Xcode, an Apple Developer account, and Homebrew, making it inaccessible for developers on other platforms or those unfamiliar with Apple's tooling.
Relies on external tools like XcodeGen and a custom CoreKiwix.xcframework, adding complexity when switching versions or compiling dependencies manually, as explained in the development steps.
Content is offline and static; updating requires downloading new ZIM files manually, which can be cumbersome compared to dynamic, real-time web access.
