Compatibility

• Minimum iOS: 15.0
• Target SDK: 15.0
• Device Types Supported: iPhone
• Screen Sizes Supported: iPhone SE to iPhone 14 Pro Max
• Orientations Supported: Portrait, Landscape

Setup

1. Clone the repository:

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

2. Install Mint:

   $ brew install mint
   

   If you're using a Mac with Apple Silicon with Mint installed via Homebrew, you may see the SwiftGen build phase fail with the following error:

   line 2: mint: command not found

   If so, or if you just 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
   

   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 14.3+.
2. Run the app in the Simulator with the Bitwarden target.

Running Tests

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.
