CloudStorage-iOS

UIKit iOS cloud storage app created as a pet project for practicing Swift, UIKit, MVVM, file management, async operations, mock services, unit tests and CI.

About

CloudStorage-iOS is an educational iOS project that simulates a small cloud storage client.

The project is focused on file management, testable architecture, local file caching and async upload/download flows. For demo purposes, the project uses a mock cloud service. The architecture allows replacing the mock implementation with a real API later.

Planned Features

• Files and folders list
• Folder creation
• File upload flow
• File download flow
• Upload and download progress
• Rename file or folder
• Delete file or folder
• File details screen
• Search
• Local file cache
• Loading / error / empty states
• MVVM architecture
• Coordinator navigation
• Protocol-based service layer
• Unit tests
• Basic memory leak prevention
• GitHub Actions CI
• SwiftLint

Tech Stack

• Swift
• UIKit
• UICollectionView
• DiffableDataSource
• MVVM
• Coordinator
• FileManager
• URLSession
• async/await
• XCTest
• GitHub Actions CI
• SwiftLint

Architecture

The project will use MVVM with a protocol-based service layer.

Main layers:

• View
• ViewModel
• Model
• CloudStorageService
• LocalFileCache
• UploadService
• DownloadService
• Coordinator

This structure makes the code easier to test, extend and maintain.
