mozilla-mobile/firefox-ios ? reverse-engineered prompt

Build me an iOS web browser app in Swift, based on this Firefox for iOS repo. I want it to open websites, feel like a normal mobile browser, and include both the main Firefox app and the simpler Focus app that are already part of this project.

Please get the repo fully set up so it builds cleanly in Xcode. Use the project’s supported iOS version, make sure the right schemes run, and fix any package or dependency issues that stop the build. If the setup needs Mozilla’s recommended tools, install or configure them and follow the repo instructions.

I’m not trying to redesign the product right now. I mainly want a working local build that I can run in the simulator or on a device, with clear notes on what you changed and how I should open and run it next time. Look up the current docs online if you need to.
