目录中的文件数组

Question

我在操场上有以下代码，我在imageURLs上获取数组。

let imagePath = str
let url = NSURL(fileURLWithPath: imagePath)
let fileManager = FileManager.default

let properties = [URLResourceKey.localizedNameKey, URLResourceKey.creationDateKey, URLResourceKey.localizedTypeDescriptionKey]
let imageURLs = try fileManager.contentsOfDirectory(at: url as URL, includingPropertiesForKeys: properties, options:FileManager.DirectoryEnumerationOptions.skipsHiddenFiles)

然后我添加＆＃34;做＆＃34; ＆＃34;捕捉＆＃34;处理项目上的错误但它停止工作。

let imagePath = Gal.urlDirectorio
let url = NSURL(fileURLWithPath: imagePath)
let fileManager = FileManager.default
let properties = [URLResourceKey.localizedNameKey, URLResourceKey.creationDateKey, URLResourceKey.localizedTypeDescriptionKey]


do { imageURLs = try fileManager.contentsOfDirectory(at: url as URL, includingPropertiesForKeys: properties, options:FileManager.DirectoryEnumerationOptions.skipsHiddenFiles)
  } catch {
       }

我按照调试过程进行操作直到＆＃34;做＆＃34;线。我没有错误，但它没有将网址添加到数组中。
