Swift 3：文件列表Optional（）

Question

i'm going nuts.

I'm trying to get the list of "txt" files from a folder but i get the list in the form of

Optional("Filename").txt

Here's my code, nothing fancy. I tried unwrapping the filename but the compiler gives me an error.I tried a "guard", a with "if", i tried "!" ... nothing works.

   let enumerator:FileManager.DirectoryEnumerator = FileManager().enumerator(atPath: myFolderPath)!

    while let element = enumerator.nextObject() as? String {

        print(element)

        if element.hasSuffix("txt") {

            fileList.append(element)
        }

    }

I need to show this list in a table view.

I hope i'm not supposed to run trought the array and get the name of the files by using a bunch o string methods just to get rid of this text...

I'm not sure what can i do! I don't really want to use this solution:

Swift: Optional Text In Optional Value

Thank you

Answer 1

@ Vadian and Rob: you guys rock, you asked the right question.

The issue was that i'm naming the .txt files with a textfield and i'm doing all the necessary work to make sure that this textfield is not empty or otherwise.

I never thought that this textfield could be optional, hence the Optional("Filename").txt

Once i unwrapped the value from the textfield Optional() had gone.

Thank you.
