无法在Swift中获得对NSNumberFormatter的引用

Question

我无法解决这个问题，请参阅此帖：Struggling with NSNumberFormatter in Swift for currency

我无法获得对NSNumberFormatter的引用...即。我无法在格式化程序上调用任何方法？ （以下引发了预期声明的错误）

if (!Input::get('password')) {
    throw new ApiException('Password not set');
}
if (User::all()->count()) {
    throw new ApiException('User already exists');
}
Artisan::call('db:seed', [
    '--class' => 'VerifyUserSeeder'
]);
$User = \Toddish\Verify\Models\User::find(1);
$User->password = Input::get('password');
$User->save();

class CurrencyFormatter {

    var price = 100

    var formatter = NSNumberFormatter()

    init() {
        formatter.numberStyle = .CurrencyStyle
        formatter.stringFromNumber(price)
    }
}
