Swift-如何在自定义目录中列出文件？

Question

I need to import a bunch of data from CSV files in my app. I have a custom folder 'CSVs' that contains a bunch of '.csv' files. Since these files will change over time, I don't want to use static filenames, but instead just loop through the 'CSVs' folder and read in all .csv files.

I tried this but no files are ever found:

func importCSV() {
    let documentsFolderPath = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)[0]
    let csvPath = (documentsFolderPath as NSString).stringByAppendingPathComponent("CSVs")
    let filemanager = NSFileManager()
    let files = filemanager.enumeratorAtPath(csvPath)
    while let file = files?.nextObject() {
        print("File: \(file)")
    }
}

If files are not being seen by your code, either or both of the following cases could be true.

• There is something wrong with your path.
• There are no files at csvPath .
