Sample app with CleanSwift architecture.

Originally this was a sample app for a job interview on iOS developer position in Biletix company (2017). It was written in Objective-C and reimplemented in Swift 5.2 with CleanSwift architecture (inspired by YARCH implementation of the original architecture). Old Objective-C version now moved into a seperate branch.

The app communicates with SOAP API and therefore network client is based on the trial version of SOAPEngine - the most supported library for SOAP API. Trial version is limited and only works on the simulator.

Implemented network client creates a new instance of SOAPEngine for every request, which is advised practice from developers of the original library.

The functionality of this demo is quite simple - it searches flight fares for selected dates and destinations. For destinations it operates IATA codes, which by default is set to MOW (for Moscow) and LED (for Saint-Petersburg).
