[ios] Establish iOS mobile app codebase #18
Description
The baseline splitbit functionality is specified by the desktop version of the app. From that functionality we need to establish a native iOS-styled design with mirror functionality with the library https://www.figma.com/community/file/1385659531316001292 reusing as much of their components as possible. I have created an initial design to help you get started https://www.figma.com/design/lzUOvguPdSF8103bGHBnDX/Split?node-id=0-1&t=yzFZkjId5V5Vf8Xo-1
The code should be available under /ios recreating the design of the figma canvas. First make a version with the hardcoded data, modularizing components, then use https://github.com/apple/swift-openapi-generator to generate data models (and possibly api clients if the generator supports it) and make the queries to the server using it.
