get file path after getting documents path

Question

I get documents path by creat

func docPath() -> String {
  let documentPaths = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)
        return documentPaths[0]
}

Now, I would like to get a file path, that file is located under document path. I tried:

let documentPath = docPath()
let filePath = documentPath.stringByAppendingPathComponent("myFile")

But I get error: Value of type 'String' has no member 'stringByAppendingPathComponent'

Why?

Apple has removed the path manipulating API from String.

Two solutions:

Bridge cast String to NSString

let filePath = (documentPath as NSString).appendingPathComponent("myFile")

Use the URL related API (recommended)

func docURL() -> URL {
    return try! FileManager.default.url(for:.documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false)
}

let documentURL = docURL()
let fileURL = documentURL.appendingPathComponent("myFile")

The code is Swift 3+.

`documentURL.appendingPathComponent` is preferable. – Jack Nov 06 '17 at 11:13 — Jack, Nov 06 '17 at 11:13

You have try this too. U have to convert to URL.

let documentPaths = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)

let documentpath : URL =  URL(fileURLWithPath: documentPaths[0])
let filePath = documentpath.appendingPathComponent("myfile")
