有没有一种方法可以使用FileManager和NSBundle来获得/Applications目录中支持给定类型文件的所有应用程序？

import Foundation

func getApplicationsForFileType(_ fileType: String) -> [String] {
    let fileManager = FileManager.default
    let applicationsPath = "/Applications"
    
    do {
        let contents = try fileManager.contentsOfDirectory(atPath: applicationsPath)
        var applications: [String] = []
        
        for item in contents {
            let itemPath = "\(applicationsPath)/\(item)"
            
            var isDirectory: ObjCBool = false
            if fileManager.fileExists(atPath: itemPath, isDirectory: &isDirectory) && isDirectory.boolValue {
                let bundleURL = URL(fileURLWithPath: itemPath)
                if let bundle = Bundle(url: bundleURL), let bundleIdentifier = bundle.bundleIdentifier {
                    if let supportedTypes = bundle.infoDictionary?["CFBundleDocumentTypes"] as? [[String: Any]] {
                        for type in supportedTypes {
                            if let typeExtensions = type["CFBundleTypeExtensions"] as? [String] {
                                if typeExtensions.contains(fileType) {
                                    applications.append(bundleIdentifier)
                                    break
                                }
                            }
                        }
                    }
                }
            }
        }
        
        return applications
    } catch {
        print("Error: \(error)")
        return []
    }
}

let fileType = "pdf"
let applications = getApplicationsForFileType(fileType)
print("支持\(fileType)文件的应用程序：\(applications)")
