Detect new file in file sharing swift

To detect new files in a file sharing system using Swift, you can use the following approaches:

File System Observer: You can use the FileManager class in Swift to observe file system changes. You can set up a file system observer to watch a specific directory for changes, such as new files being added. Here's an example:
```
import Foundation
```

let fileManager = FileManager.default let directoryPath = "/path/to/directory"

do { try fileManager.startMonitoringDirectory(atPath: directoryPath, for: [.fileCreated]) print("Monitoring directory for file changes...") } catch { print("Error monitoring directory: (error)") }

In this example, the `startMonitoringDirectory` method is used to start monitoring the specified directory for file system changes. The `for` parameter specifies the types of changes to monitor, in this case, `.fileCreated` to detect new files being added.

2. **File Sharing Extension**: If you're building a file sharing app, you can use a file sharing extension to detect new files being shared. A file sharing extension is a type of app extension that allows you to access and manipulate files shared by other apps.

To detect new files in a file sharing extension, you can use the `NSFileProvider` class to monitor the file provider's `fileProvider` property for changes. Here's an example:
```swift
import FileProvider

class FileSharingExtension: NSObject, NSFileProviderDelegate {
    func fileProvider(_ fileProvider: NSFileProvider, didAdd file: URL) {
        print("New file added: \(file.path)")
    }
}

In this example, the didAdd method is called when a new file is added to the file provider. You can use this method to detect new files being shared.

Cloud Storage: If you're using a cloud storage service such as iCloud or Google Drive, you can use the corresponding SDKs to detect new files being added to the cloud storage.

For example, with iCloud, you can use the iCloud framework to monitor the iCloudURL property for changes. Here's an example:

import iCloud

class iCloudObserver: NSObject, iCloudObserverDelegate {
    func iCloud(_ iCloud: iCloud, didAdd file: URL) {
        print("New file added: \(file.path)")
    }
}

In this example, the didAdd method is called when a new file is added to the iCloud storage. You can use this method to detect new files being shared.

Polling: As a last resort, you can use polling to detect new files in a file sharing system. This involves periodically checking the file system or cloud storage for new files. Here's an example:
```
import Foundation
```

let fileManager = FileManager.default let directoryPath = "/path/to/directory"

let timer = Timer.scheduledTimer(withTimeInterval: 1.0, repeats: true) { _ in do { let files = try fileManager.contentsOfDirectory(atPath: directoryPath) if files.count > 0 { print("New files detected: (files)") } } catch { print("Error getting file list: (error)") } }


In this example, a timer is used to periodically check the file system for new files. The `contentsOfDirectory` method is used to get a list of files in the specified directory, and if the list is not empty, it means new files have been added.

Note that polling can be resource-intensive and may not be suitable for large-scale file sharing systems.
