Summary of ChangesHello @obadasemary, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request introduces a comprehensive refactoring of the application's core architecture, transitioning from MVVM to VIPER. This change aims to enhance the modularity, testability, and maintainability of the codebase by enforcing a clearer separation of concerns between the presentation logic (Presenter) and business logic (Interactor). The migration involved systematic renaming of components and updating all associated code and documentation across every feature module. Highlights

Code Review
This pull request completes a significant architectural refactoring, migrating the codebase from MVVM to VIPER naming conventions. The changes are extensive, touching nearly every module to rename ViewModels to Presenters and UseCases to Interactors. The updates are consistent and thorough, including corresponding changes in protocols, variable names, builders, and test files. I also noticed that this refactoring correctly splits what was previously a monolithic CoreInteractor into module-specific interactors (e.g., ExploreInteractor, ProfileInteractor), which is a great improvement for modularity and separation of concerns. The documentation has also been updated to reflect the new architecture. Overall, this is a well-executed, large-scale refactoring that improves architectural consistency and modularity.

For consistency with the VIPER refactoring, the local variable holding the BookmarksPresenter instance should be named presenter instead of viewModel. This improves clarity and aligns with the new architectural naming scheme.
| let viewModel = BookmarksPresenter( | |
| bookmarksInteractor: bookmarksInteractor, | |
| router: bookmarksRouter | |
| ) | |
| return BookmarksView(viewModel: viewModel) | |
| return BookmarksView(presenter: viewModel) | |
| let presenter = BookmarksPresenter( | |
| bookmarksInteractor: bookmarksInteractor, | |
| router: bookmarksRouter | |
| ) | |

🎯 Recommendations
Before Merging (Required)
- Update file header comments in all Presenter files to match actual filenames
- Run full test suite to ensure no regressions (as noted in PR description: ✅ done)
- Build on simulator to verify compilation (as noted in PR description: ✅ done)
Optional Improvements
- Rename test files from
*ViewModelTests.swift→*PresenterTests.swift - Update inline comments that reference "UseCase" terminology
- Update error message strings in preconditionFailure calls
✅ Final Verdict
APPROVED with minor fixes recommended
This is an excellent refactoring that successfully migrates the entire codebase to proper VIPER naming conventions. The execution is methodical, thorough, and maintains all existing functionality.
Why This PR is Good:
- ✅ Complete and consistent migration
- ✅ All tests updated and passing
- ✅ Documentation updated
- ✅ No breaking changes to logic
- ✅ Excellent commit structure
- ✅ Proper dependency injection maintained
Minor Issues (Non-Blocking):
⚠️ File header comments need updating (cosmetic)⚠️ Some inline comments reference old names (cosmetic)⚠️ Test file names could be updated (cosmetic)
Recommendation: Merge after fixing the file header comments. The other issues are cosmetic and can be addressed in a follow-up PR if desired.
Great work on this architectural cleanup! 🎉
