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!

Why is this the case? Does anyone know?

The first option of this answer is wrong for a file path. It would only work if it's a full file:// URL string.

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.

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.

Leo Dabus Over a year ago

@natev not if the fileURL string contains the scheme "file://" as well if it was obtained using absoluteString instead of the path property.

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

var filePathUrl = NSURL.fileURLWithPath(path)

Use String Extension for swift 5 for convert string into URL:

extension String {
    // Support Properties
    var absoluteURL: URL? {
        let _url = URL(string: self)
        return _url
    }
    
    var absoluteURLFromPath: URL? {
        let _url = URL(fileURLWithPath: self)
        return _url
    }
}

Usage

print(filePath.absoluteURL ?? filePath.absoluteURLFromPath ?? "Invalid") // It is convert path into URL

This is not for Swift 5. This would be valid even for Swift 3. And what's the benefit of this extension? It's no less code for the user.
