Project description

1) Programming Language: All code is written exclusively in Swift. There are only a few classes written in Objective-C, which are necessary for interoperability with C++ code.

2) User Interface: Legacy code uses Storyboards and NIB files, but new code is written programmatically.

3) Data Storage: CoreData is used for data management. Experience with multithreading is required.

4) Unit Tests: The Nimble framework is used for unit testing.

5) UI Tests: Cucumber is used for user interface testing.

6) Compatibility: The minimum supported iOS version is 15.

7) Build System: Tuist is used for dependency management and project building.

8) C++ Integration: Occasionally, reading and integrating C++ code is required.

9) Reactive Programming: RxSwift is actively used in the project.

10) Architecture: New code follows the MVVM architectural pattern with the use of Coordinators.

11) Modularity: The project uses a multi-module architecture with more than 40 modules, and the number of modules is constantly increasing.

12) Legacy Code: The project includes legacy code that needs to be worked with from time to time. It is important to be able to understand existing code and make changes safely.
