import Foundation

func createFileInSharedFolder() {
    let fileManager = FileManager.default
    let sharedContainerURL = fileManager.containerURL(forSecurityApplicationGroupIdentifier: "group.com.example.sharedcontainer")
    
    if let sharedFolderURL = sharedContainerURL?.appendingPathComponent("SharedFolder") {
        do {
            try fileManager.createDirectory(at: sharedFolderURL, withIntermediateDirectories: true, attributes: nil)
            
            let fileURL = sharedFolderURL.appendingPathComponent("example.txt")
            let fileContent = "This is an example file."
            try fileContent.write(to: fileURL, atomically: true, encoding: .utf8)
            
            print("File created successfully at \(fileURL.path)")
        } catch {
            print("Error creating file: \(error)")
