DuckDuckGo iOS

We are excited to engage the community in development!

We are hiring!

DuckDuckGo is growing fast and we continue to expand our fully distributed team. We embrace diverse perspectives, and seek out passionate, self-motivated people, committed to our shared vision of raising the standard of trust online. If you are a senior software engineer capable in either iOS or Android, visit our careers page to find out more about our openings!

Building

Submodules

We use submodules, so you will need to bring them into the project in order to build and run it:

Run git submodule update --init --recursive

Developer details

If you're not part of the DuckDuckGo team, you should provide your Apple developer account id, app id, and group id prefix in an ExternalDeveloper.xcconfig file. To do that:

1. Run cp Configuration/DuckDuckGoDeveloper.xcconfig Configuration/ExternalDeveloper.xcconfig
2. Edit Configuration/ExternalDeveloper.xcconfig and change the values of all fields
3. Clean and rebuild the project

Dependencies

We use Swift Package Manager for dependency management, which shouldn't require any additional set up.

SwiftLint

We use SwifLint for enforcing Swift style and conventions, so you'll need to install it.

Fonts

We use Proxima Nova fonts which are proprietary and cannot be committed to source control, see fonts.

Debugging

Instruments

We have Custom Instruments tool to help visualize and track events that happen during runtime.

In order to run it:

1. Build a Debug version and install it on Simulator/Device.
2. Select Instruments target and run it on a Mac. A New instance of Instruments app will be run that has a grayed out icon indicating that it works in debug mode with custom instruments attached.
3. Select 'DDG Trace' template or set up a custom one by importing 'DDG Timeline' instrument from Library.
4. Start recording.

See Instruments Developer Help for reference how to create custom instruments.

Terminology

We have taken steps to update our terminology and remove words with problematic racial connotations, most notably the change to main branches, allow lists, and blocklists. Closed issues or PRs may contain deprecated terminology that should not be used going forward.
