How to split filename from file extension in Swift?

Question

Given the name of a file in the bundle, I want load the file into my Swift app. So I need to use this method:

let soundURL = NSBundle.mainBundle().URLForReso         


        

Answer 1

Creates unique "file name" form url including two previous folders

func createFileNameFromURL (colorUrl: URL) -> String {

    var arrayFolders = colorUrl.pathComponents

    // -3 because last element from url is "file name" and 2 previous are folders on server
    let indx = arrayFolders.count - 3
    var fileName = ""

    switch indx{
    case 0...:
        fileName = arrayFolders[indx] + arrayFolders[indx+1] + arrayFolders[indx+2]
    case -1:
        fileName = arrayFolders[indx+1] + arrayFolders[indx+2]
    case -2:
        fileName = arrayFolders[indx+2]
    default:
        break
    }


    return fileName
}
