iOS Build an Interactive Story App with Swift 2 Creating a Story Creating an Adventure

The code he has on the screen and that on the Link to code snippet list are different.

The snippet says 

struct Adventure {
    static func story(name: String) -> Page {

the code he writes says the below

struct Adventure {
    static var story: Page {

Then, I have an issue with the below, 

    let returnTrip = Page(story: .ReturnTrip)) -RETURN TRIP TURNS BLUE/GREEN, NONE OF THE OTHER REFERENCES TO MEMBERS BELOW DO, THEY DO IN HIS VIDEO
    let touchdown = returnTrip.addChoice("Stop and Investigate", story: .TouchDown)
    let homeward = returnTrip.addChoice("Continue Home to Earth", story: .Homeward)

    let rover = touchdown.addChoice("Explore the Rover", story: .Rover)
    let crate = touchdown.addChoice("Open the Crate", story: .Crate)

    homeward.addChoice("Head back to Mars", page: touchdown)
    let home = homeward.addChoice("Continue Home to Earth", story: .Home)

    let cave = rover.addChoice("Explore the Coordinates", story: .Cave)
    rover.addChoice("Return to Earth", page: home)

    cave.addChoice("Continue towards faint light", story: .Droid))
    cave.addChoice("Refill the ship and explore the rover", page: rover)

    crate.addChoice("Explore the Rover", page: rover)
    crate.addChoice("Use the key", story: .Monster)

Remove the extra parenthesis after .ReturnTrip and .Droid to get rid of the errors.

Also, the code difference that you mentioned at the top of your post comes into play later. Use what you see in the video. Otherwise you'll receive an error in your ViewController.

struct Adventure { static var story: Page {

You'll change it to what's in the code snippet later on in "Refactoring the Model Layer"

struct Adventure { static func story(name: String) -> Page {

Yes, do as Felix Chu said in his comment and you'll be all good. ("Remove the extra parentheses after .ReturnTrip and .Droid to get rid of the errors.")

I've sent a pm to @pasanpr about this also.
