Wikipedia iOS
The official Wikipedia iOS app.
- License: MIT License
- Source repo: https://github.com/wikimedia/wikipedia-ios
- Planning (bugs & features): https://phabricator.wikimedia.org/project/view/782/
- Team page: https://www.mediawiki.org/wiki/Wikimedia_Apps/Team/iOS
Note: The latest main branch is set up to build with Xcode 12.
Building and Running
In the directory, run ./scripts/setup
. Note: going to scripts
directory and running setup
will not work due to relative paths.
Running scripts/setup
will setup your computer to build and run the app. The script assumes you have Xcode installed already. It will install homebrew, Carthage, and ClangFormat. It will also create a pre-commit hook that uses ClangFormat for linting.
After running scripts/setup
, you should be able to open Wikipedia.xcodeproj
and run the app on the iOS Simulator (using the Wikipedia scheme and target). If you encounter any issues, please don't hesitate to let us know via a bug report or messaging us on IRC in #wikimedia-mobile on Freenode.
Required dependencies
If you'd rather install the development prerequisites yourself without our script:
- Xcode - The easiest way to get Xcode is from the App Store, but you can also download it from developer.apple.com if you have an AppleID registered with an Apple Developer account.
- Carthage - We check in prebuilt dependencies to simplify the initial build and run experience but you'll still need Carthage installed to allow Xcode to properly copy the frameworks into the built app. After you add, remove, or upgrade a dependency, you should run
scripts/carthage_update
to update the built dependencies. - ClangFormat - We use this for linting
Contributing
Covered in the contributing document.
Development Guidelines
These are general guidelines rather than hard rules.
Objective-C
Swift
Formatting
We use Xcode's default 4 space indentation and our .clang-format
file with the pre-commit hook setup by scripts/setup
. Currently, this does not enforce Swift formatting.
Process and code review norms
Covered in the process document.
Testing
The Wikipedia scheme is configured to execute the project's iOS unit tests, which can be run using the Cmd+U
hotkey or the Product->Test menu bar action. Screenshot tests will fail unless you are running on one of the configurations defined by configurations_to_test_on_pull
in fastlane/Fastfile
. In order for the tests to pass, the test device's language and region must be set to en-US
in Settings > General > Language & Region. There is a ticket filed to update the tests to pass regardless of region and language.
Targets
Wikipedia
Points to production servers.
Staging
Points to the Apps team's staging environment for page content and production for everything else. Has additional debugging menus and is pushed to TestFlight as a separate app bundle.
Local Page Content Service and Announcements
Points to the mobileapps and wikifeeds repos running locally.
MediaWiki Beta Cluster
Points to the MediaWiki beta cluster for MediaWiki API calls and production for everything else.
RTL
Launches the app in an RTL locale using the -AppleLocale argument.
Experimental
For one off builds, can point to whatever is needed for the given experiment.
User Testing
For user testing. Has an alternate configuration so that it can be delivered ad hoc.
Event Logging Dev Debug
For testing the events that the app sends to Event Logging. Points to the Event Logging staging environment.
Beta Cluster tests
Tests that run against the MediaWiki beta cluster, checking for upstream changes to MediaWiki that might break any assumptions we have.
UITests
Runs automated screenshot tests.
WMF
Bundles up the app logic shared between the main app and the extensions (widgets, notifications).
Updating localizations
Covered in the localization document.
Adding new Wikipedia languages or updating language configurations
Covered in the languages document.
{{name}}Widget, {{name}}Notification, {{name}}Stickers
Extensions for widgets, notifications, and stickers.
codemirror-config
Generates the CodeMirror configuration files. CodeMirror is used in the section editor.
Continuous integration
Covered in the ci document.
Event logging
Covered in the event logging document.
Web development
The article view and several other components of the app rely on web components. Instructions for working on these components is covered in the web development document.
