在Swift 2.2中查找系统上文件或目录的所有者

import Foundation

func findOwnerOfFileOrDirectory(atPath path: String) -> String? {
    let fileManager = NSFileManager.defaultManager()
    
    do {
        let attributes = try fileManager.attributesOfItemAtPath(path)
        if let owner = attributes[NSFileOwnerAccountName] as? String {
            return owner
        }
    } catch {
        print("Error: \(error)")
    }
    
    return nil
}

// 示例用法
let path = "/path/to/file"
if let owner = findOwnerOfFileOrDirectory(atPath: path) {
    print("文件或目录的所有者是：\(owner)")
} else {
    print("无法找到文件或目录的所有者")
}
