How do you instantiate a Storyboard from a file within an iOS playground?

问题

Let's assume you've copied a Main.storyboard from an Xcode 6 project into a standalone playground's Resources directory. How can you instantiate a UIStoryboard using the Main.storyboard file? Trying to use the default via nil doesn't work:

let storyboard = UIStoryboard(name: "Main", bundle: nil)

Nor does explicitly using the main bundle:

let storyboard = UIStoryboard(name: "Main", bundle: NSBundle.mainBundle())

Even if the playground is part of the storyboard's Xcode project, I receive the same error: "Could not find a storyboard named 'main' in bundle NSBundle..."

Seems that the bundle path is correct and should be able to deserialize the storyboard file.

I found this:

"You can throw a xib file into your Resources, but the playground cannot read it or run it because it’s not in compiled form. Today, I (finallly!) thought of using ibtool to pre-compile my MainMenu.xib file into nib and then load that. When you install Xcode’s command line tools, ibtool gets added to /usr/bin. So all you need to do to compile your nib is issue the following command:

ibtool --compile MainMenu.nib MainMenu.xib`

Throw that resulting nib into your playground’s resources folder and you’re ready to load it up."

Your storyboard will be compiled into multiple nibs (one per scene)

Hope it helps

Similar to @ybakos answer, but for accessing a framework with a storyboard you want to load (then both the Playground and your app can use the same storyboard directly):

If you have a Storyboard in a framework that has been compiled for the simulator and is also embedded in a working project that furthermore lives in a workspace, you will be able to load the framework in a playground in that same workspace via the framework bundle, like so:

let frameworkBundle = Bundle(identifier: "com.kigisoft.KGWeatherMap")
let storyboard = UIStoryboard(name: "WeatherMap", bundle: frameworkBundle)

You can download a sample project "StoryboardPlay" from this Dropbox link:
