How to convert this var string to URL in Swift

Question

I need url filepath be a URL (NSURL in old versions of Swift). I have this:

let paths = NSSearchPathForDirectoriesInDomains(
        .documentDirectory, .userDomainMask, true)

// NSString *documentsDirectory = [paths objectAtIndex:0];
let documentsDirectory = paths[0] as String

var filePath:String? = nil
var fileNamePostfix = 0
repeat {
    filePath =
    "\(documentsDirectory)/\(dateTimePrefix)-\(fileNamePostfix).mp4"
    fileNamePostfix += 1
} while (FileManager.default.fileExists(atPath: filePath))

I need to convert this to URL for use in self.fileOutput.startRecording(to: <#outputFileURL: URL?#>, recordingDelegate: <#AVCaptureFileOutputRecordingDelegate?#>) method.

I tried filePath as? URL() but it isn't correct.

you need to do:

let fileUrl = URL(string: filePath)

or

let fileUrl = URL(fileURLWithPath: filePath)

depending on your needs. See URL docs

Before Swift 3, URL was called NSURL.

Swift 4: first one gives nil, second one works for paths like "/dir/file.ext". Thank you! – William T. Mallard Mar 31 '18 at 23:10

In swift 3 use:

let url = URL(string: "Whatever url you have(eg: https://google.com)")

thanks , it worked for me , earlier I was using URL.init(fileURLWithPath: <#T##String#>) which was producing wrong url. I think thats for some file path. – Rajath Kornaya Jun 05 '18 at 08:08

in swift 4 to convert to url use URL

let fileUrl = URL.init(fileURLWithPath: filePath)

or

let fileUrl = URL(fileURLWithPath: filePath)

This will return `nil` if the path contains strings! Use `let fileUrl = URL(fileURLWithPath: filePath)` instead. – natevw Feb 15 '18 at 21:10
@natev not if the fileURL string contains the scheme `"file://"` as well if it was obtained using `absoluteString` instead of the `path` property. – Leo Dabus Mar 30 '21 at 19:53

To Convert file path in String to NSURL, observe the following code

var filePathUrl = NSURL.fileURLWithPath(path)
