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 = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
    NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"/MyFolder"];

    if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
    [[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error];

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)
}
