Robię to w następujący sposób:
NSError *error;
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]; //Create folder

Nie mam wystarczającej reputacji, aby skomentować odpowiedź Manniego, ale [paths objectAtIndex :0] jest standardowym sposobem uzyskania katalogu dokumentów aplikacji
Ponieważ NSSearchPathForDirectoriesInDomains funkcja została zaprojektowana pierwotnie dla Mac OS X, gdzie tam może być więcej niż jeden z tych katalogów, zwraca tablicę ścieżek raczej niż jedna ścieżka. W iOS, wynikowa tablica powinna zawierać pojedyncza ścieżka do katalogu. Listing 3-1 pokazuje typowe zastosowanie tego funkcja.
Listing 3-1 Getting the path to the katalog dokumentów aplikacji
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

Swift 3 Rozwiązanie:
private func createImagesFolder() {
// path to documents directory
let documentDirectoryPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first
if let documentDirectoryPath = documentDirectoryPath {
// create the custom folder path
let imagesDirectoryPath = documentDirectoryPath.appending("/images")
let fileManager = FileManager.default
if !fileManager.fileExists(atPath: imagesDirectoryPath) {
do {
try fileManager.createDirectory(atPath: imagesDirectoryPath,
withIntermediateDirectories: false,
attributes: nil)
} catch {
print("Error creating images folder in documents dir: \(error)")
}
}
}
}

Nie podoba mi się "[paths objectAtIndex:0]", ponieważ jeśli Apple doda nowy folder zaczynający się od "A", "B" lub "C", folder "Documents"nie jest pierwszym folderem w katalogu.
Lepiej:
NSString *dataPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/MyFolder"];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder

Swift 2 rozwiązanie:
let documentDirectoryPath: String = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first!
if !NSFileManager.defaultManager().fileExistsAtPath(documentDirectoryPath) {
do {
try NSFileManager.defaultManager().createDirectoryAtPath(documentDirectoryPath, withIntermediateDirectories: false, attributes: nil)
} catch let createDirectoryError as NSError {
print("Error with creating directory at path: \(createDirectoryError.localizedDescription)")
}
}

To działa dobrze dla mnie,
NSFileManager *fm = [NSFileManager defaultManager];
NSArray *appSupportDir = [fm URLsForDirectory:NSDocumentsDirectory inDomains:NSUserDomainMask];
NSURL* dirPath = [[appSupportDir objectAtIndex:0] URLByAppendingPathComponent:@"YourFolderName"];
NSError* theError = nil; //error setting
if (![fm createDirectoryAtURL:dirPath withIntermediateDirectories:YES
attributes:nil error:&theError])
{
NSLog(@"not created");
}

Poniższy kod może pomóc w tworzeniu katalogu:
-(void) createDirectory : (NSString *) dirName {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Fetch path for document directory
dataPath = (NSMutableString *)[documentsDirectory stringByAppendingPathComponent:dirName];
NSError *error;
if (![[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]) {
NSLog(@"Couldn't create directory error: %@", error);
}
else {
NSLog(@"directory created!");
}
NSLog(@"dataPath : %@ ",dataPath); // Path of folder created
}
Użycie:
[self createDirectory:@"MyFolder"];
Wynik:
Katalog stworzony!

Swift 1.2 i iOS 8
Utwórz własny katalog (name = "MyCustomData") wewnątrz katalogu documents, ale tylko wtedy, gdy katalog nie istnieje.
// path to documents directory
let documentDirectoryPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first as! String
// create the custom folder path
let myCustomDataDirectoryPath = documentDirectoryPath.stringByAppendingPathComponent("/MyCustomData")
// check if directory does not exist
if NSFileManager.defaultManager().fileExistsAtPath(myCustomDataDirectoryPath) == false {
// create the directory
var createDirectoryError: NSError? = nil
NSFileManager.defaultManager().createDirectoryAtPath(myCustomDataDirectoryPath, withIntermediateDirectories: false, attributes: nil, error: &createDirectoryError)
// handle the error, you may call an exception
if createDirectoryError != nil {
println("Handle directory creation error...")
}
}

Swift 4.0
var paths: [Any] = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
let documentsDirectory: String = paths[0] as? String ?? ""
// Get documents folder
let dataPath: String = URL(fileURLWithPath: documentsDirectory).appendingPathComponent("/MyFolder").absoluteString
if !FileManager.default.fileExists(atPath: dataPath) {
try? FileManager.default.createDirectory(atPath: dataPath, withIntermediateDirectories: false, attributes: nil)
