If anyone ever encounters this, do the following two things
1) Add a run script for your extension target.

cd "${CONFIGURATION_BUILD_DIR}/${UNLOCALIZED_RESOURCES_FOLDER_PATH}/"

if [[ -d "Frameworks" ]]; then

rm -fr Frameworks

fi

2) http://stackoverflow.com/questions/25777958/validation-error-invalid-bundle-the-bundle-at-contains-disallowed-file-fr/25789145#25789145

Set Embedded Content Contains Swift Code: NO for the extension target only.

Credits to my superior who solved the former.

deleteCookie in swift

var cookieJar:[NSHTTPCookie] = NSHTTPCookieStorage.sharedHTTPCookieStorage().cookies as! [NSHTTPCookie]

        
if cookieJar.isEmpty == false {




    println("\n\n\nnot null\n\n\n")

    for cookie in cookieJar {

        NSHTTPCookieStorage.sharedHTTPCookieStorage().deleteCookie(cookie as NSHTTPCookie)

    }

}

Checking for nil

This occurred to me for a week.
In Objective-C, to check for nil, we can just
if (varName) {
    //not nil
} else {
    //nil
}
and do note that one handy thing in objective-c is that when you declare a variable, it assigns 0.

But thanks to optionals in swift, variables are not supposed to be nil.
So I was checking if cookies are persisting. And found out that I always return true, even if the println(cookie) result is
[]


So in Swift, you have to either call isEmpty
if cookieArray?.isEmpty == false{
     //cookie stored
} else {
    //no cookie :(
}

How to have 2 different UIPickerView for 2 different UITextField in the same UIViewController

Initial attempt:
drag 2 UIPickerView and control drag them and apply constraints to fit them to the bottom

However~
this will make your storyboard hard to maintain and messy, especially if you have UI elements that needed to be changed in the future.

The better solution could be:
Create 2 UIPickerView programatically

var statesPickerView: UIPickerView!
var phoneNumberPickerView: UIPickerView!

and then your toolbar(for Done or maybe stepper for form input)

var keyboardToolbar: UIToolbar!
keyboardToolbar = UIToolbar()
        keyboardToolbar.sizeToFit()
        var flexSpace = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
        var doneButton: UIBarButtonItem = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Done, target: self, action: Selector("dismissPickerView"))

        var barButtonItemsArray = NSMutableArray()
        barButtonItemsArray.addObject(flexSpace)
        barButtonItemsArray.addObject(doneButton)
        keyboardToolbar.items = barButtonItemsArray as [AnyObject]
        keyboardToolbar.sizeToFit()

add the toolbars to the inputview(picker view)
        self.phoneCodeTextField.inputAccessoryView = keyboardToolbar
        self.statesTextField.inputAccessoryView = keyboardToolbar
        self.phoneNumberPickerView = UIPickerView()
        self.statesPickerView = UIPickerView()

don't forget the delegates
        self.phoneNumberPickerView.dataSource = self
        self.statesPickerView.dataSource = self
        self.phoneNumberPickerView.delegate = self
        self.statesPickerView.delegate = self

 assign the pickerview as the inputview for the UITextFields
        self.phoneCodeTextField.inputView = phoneNumberPickerView
        self.statesTextField.inputView = statesPickerView


Another thing to note, you don't have to set the position or CGRectMake for your pickerview, thanks to the inputView property(e.g. your keyboard is at the bottom anyways).

Status bar text

Sometimes your design requires you to use a black navigation controller header. Which will camouflage your status' bar text.

So to change the status' bar text color you are required to do two things:

1) Go to info.plist(note it's the one in the ROOT folder, NOT the one in Supporting Files)
Add a new property "View controller-based status bar appearance" with the value NO

2) go to AppDelegate.swift and add in the following line

UIApplication.sharedApplication().setStatusBarStyle(.LightContent, animated: true)
