ios - 是否可以以编程方式检索安装在 mac os 上的应用程序图标？

Question

public func getAllApplications() -> [NSMetadataItem] {
    let fileManager = FileManager()

    guard let applicationsFolderUrl = try? FileManager.default.url(for: .applicationDirectory, in: .localDomainMask, appropriateFor: nil, create: false) else { return [] }

    let applicationUrls = try! fileManager.contentsOfDirectory(at: applicationsFolderUrl , includingPropertiesForKeys: [], options: [FileManager.DirectoryEnumerationOptions.skipsPackageDescendants, FileManager.DirectoryEnumerationOptions.skipsSubdirectoryDescendants])

    guard let systemApplicationsFolderUrl = try? FileManager.default.url(for: .applicationDirectory, in: .systemDomainMask, appropriateFor: nil, create: false) else { return [] }

    let utilitiesFolderUrl = NSURL.init(string: "\(systemApplicationsFolderUrl.path)/Utilities") as! URL

    guard let utilitiesUrls = try? fileManager.contentsOfDirectory(at: utilitiesFolderUrl, includingPropertiesForKeys: [], options: [FileManager.DirectoryEnumerationOptions.skipsPackageDescendants, FileManager.DirectoryEnumerationOptions.skipsSubdirectoryDescendants]) else { return [] }

    let urls = applicationUrls + utilitiesUrls

    var applications = [NSMetadataItem]()

    for url in urls {
        print(url.path, fileManager.isExecutableFile(atPath: url.path))
        if fileManager.isExecutableFile(atPath: url.path) {
            guard let mdi = NSMetadataItem(url: url) else { continue }
            applications.append(mdi)
        }
    }

    for app in applications {
        print(app.value(forAttribute: kMDItemDisplayName as String))
    }
    return applications
}

我能够检索使用上述代码安装的应用程序的名称，并且从这里我无法弄清楚如何检索图标图像。我找不到任何允许我检索图标信息的属性，或者我可能在错误的地方看到了。

任何形式的帮助表示赞赏。谢谢！
