Compatibility

• Minimum iOS: 15.0
• Target SDK: 15.0
• Device Types Supported: iPhone, iPad
• Screen Sizes Supported: iPhone SE to iPhone 16 Pro Max, iPad Mini to iPad Pro 12.9"
• Orientations Supported: Portrait, Landscape

Setup

1. Clone the repository:

   $ git clone https://github.com/bitwarden/ios

2. Install Mint:

   $ brew install mint

   Alternatively, if you prefer to install Mint without brew, clone the Mint repo into a temporary directory and run make.

   $ git clone https://github.com/yonaskolb/Mint.git
   $ cd Mint
   $ make

3. Bootstrap the project:

   $ Scripts/bootstrap.sh

   Hint For development purposes it's possible to use a local build of the Bitwarden SDK by setting the environment variable LOCAL_SDK to true before running the bootstrap script. Review Linking SDK to clients for more details.

   Note Because Scripts/bootstrap.sh is how the project is generated, bootstrap.sh will need to be run every time the project configuration or file structure has changed (for example, when files have been added, removed or moved). It is typically best practice to run bootstrap.sh any time you switch branches or pull down changes.

   Alternatively, you can create git hooks to automatically execute the bootstrap.sh script every time a git hook occurs. To use the git hook scripts already defined in the Scripts directory, copy the scripts to the .git/hooks directory.

   $ cp Scripts/post-merge .git/hooks/
   $ cp Scripts/post-checkout .git/hooks/

Run the App

1. Open the project in Xcode 16.1+.
2. Run the app in the Simulator with the Bitwarden target.

Running Tests

The test target requires running in an iPhone 16 Pro simulator running iOS 18.1. While our snapshot tests work off of enforced device dimensions, small differences can still arise between devices and iOS versions, and this makes sure our snapshots are as consistent as we can make them in testing.

1. In Xcode's toolbar, select the project and a connected device or simulator.

   • The Generic iOS Device used for builds will not work for testing.

2. In Xcode's menu bar, select Product > Test.

   • Test results appear in the Debug Area, which can be accessed from View > Debug Area > Show Debug Area if not already visible.

Linting

This project is linted using both SwiftLint and SwiftFormat. Both tools run in linting mode with every build of the Bitwarden target. However, if you would like to have SwiftFormat autocorrect any issues that are discovered while linting, you can manually run the fix command mint run swiftformat ..

Additionally, if you would like SwiftFormat to autocorrect any issues before every commit, you can use a git hook script. To use the git hook script already defined in the Scripts directory, copy the script to the .git/hooks directory.

$ cp Scripts/pre-commit .git/hooks/

Project Structure

BitwardenShared

This project's structure is split into separate sections to support sharing as much code between all of the targets as possible. All core functionality and the majority of UI elements can be found in the BitwardenShared framework.

GlobalTestHelpers

GlobalTestHelpers is a directory that contains helper files used in all test targets. This directory is included in each target that is defined in the project.yml file.
