How to create directory using Swift code (NSFileManager)

Question

I\'m having some trouble with converting Objective-C code to create a directory for Swift.

Objective-C:

    NSArray *paths = NSSearchPathForDirectori

Simpler solution:

"~/Desktop/demo".expand.createDir()//Now you have a folder named demo on your desk

extension String{
    func createDir(_ path:String){
        do {
            try FileManager.default.createDirectory(atPath: path, withIntermediateDirectories: true, attributes: nil)
        } catch let error as NSError {
            NSLog("Unable to create directory \(error.debugDescription)")
        }
    }
    var expand:String {return NSString(string: self).expandingTildeInPath}
}

Swift 4 :

NSSearchPathForDirectoriesInDomains returns an array of strings, not URLs.

appendingPathComponent to string makes app crash with the message -[NSPathStore2 URLByAppendingPathComponent:]: unrecognized selector sent to instance

Here's a Swift 4 version that compiles:

    let paths = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)
    if let pathURL = URL.init(string: paths[0]) {
        let dataURL = pathURL.appendingPathComponent("MyFolder")
        do {
            try FileManager.default.createDirectory(atPath: dataURL.absoluteString, withIntermediateDirectories: true, attributes: nil)
        } catch let error as NSError {
            print(error.localizedDescription);
        }
    }
    else {
        print("Error in getting path URL");
    }

Swift 5

guard let path = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true).first else { return }
    if let pathURL = URL.init(string: path) {
        let dataURL = pathURL.appendingPathComponent("MyFolderName")
        do {
            try FileManager.default.createDirectory(atPath: dataURL.absoluteString, withIntermediateDirectories: true, attributes: nil)
        } catch let error as NSError {
            print(error.localizedDescription);
        }
    }
    else {
        print("Error in URL path");
    }

The accepted answer no longer compiles as the line with appendingPathComponent generates an error.

Here's a Swift 3 version that compiles:

fileprivate func createDir(dirName: String) {
    let documentsDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
    let dataPath = documentsDirectory.appendingPathComponent(dirName)

    do {
        try FileManager.default.createDirectory(atPath: dataPath.absoluteString, withIntermediateDirectories: false, attributes: nil)
    } catch let error as NSError {
        printError("Error creating directory: \(error.localizedDescription)")
    }
}

Swift 5.0

let paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
let documentsDirectory = paths[0]
let docURL = URL(string: documentsDirectory)!
let dataPath = docURL.appendingPathComponent("MyFolder")
if !FileManager.default.fileExists(atPath: dataPath.absoluteString) {
    do {
        try FileManager.default.createDirectory(atPath: dataPath.absoluteString, withIntermediateDirectories: true, attributes: nil)
    } catch {
        print(error.localizedDescription);
    }
}

Swift 4.0

let paths = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)
let documentsDirectory: AnyObject = paths[0] as AnyObject
let dataPath = documentsDirectory.appendingPathComponent("MyFolder")!

do {
    try FileManager.default.createDirectory(atPath: dataPath.absoluteString, withIntermediateDirectories: false, attributes: nil)
} catch let error as NSError {
    print(error.localizedDescription);
}

Swift 3.0

let paths = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)
let documentsDirectory: AnyObject = paths[0]
let dataPath = documentsDirectory.appendingPathComponent("MyFolder")!

do {
    try FileManager.default.createDirectory(atPath: dataPath.absoluteString, withIntermediateDirectories: false, attributes: nil)
} catch let error as NSError {
    print(error.localizedDescription);
}

Swift 2.1

You can create directory using below method:

let paths = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)
let documentsDirectory: AnyObject = paths[0]
let dataPath = documentsDirectory.stringByAppendingPathComponent("MyFolder")

do {
    try NSFileManager.defaultManager().createDirectoryAtPath(dataPath, withIntermediateDirectories: false, attributes: nil)
} catch let error as NSError {
    print(error.localizedDescription);
}

For Other developers, Im gonna leave this here as it may help someone like me looking for a way to figure out where the folder is being created.

let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true) as NSArray
let documentsDir = paths.firstObject as String
println("Path to the Documents directory\n\(documentsDir)")
