//that one works perfectly! case sensitive**** //all String values are in lower case(tricky huh!)

enum MobilePhone { case iphone(String) case android(String) //case Blackberry(String) case windowsPhone(String) }

let iphone = MobilePhone.iphone("7 Plus")

Hello Mackenzy Douyon I think the code goes like this, they only one to assign a "7 Plus" to the iphone. But I don't know why i still get an error.!

enum Mobilephone { case iphone(String) case android(String) case windowsPhone(String) }

let iphone = .iphone("7 Plus")

I also found the other mistake the challenge is saying that it will give you four cases when is only giving you three this is the correct answer

enum MobilePhone { case iphone(String) case android(String) case blackBerry(String) case windowsPhone(String) }

let iphone = MobilePhone.iphone("7 Plus")

So weird because it does work on my end.

enum MobilePhone { case iphone(String) case android(String) case blackBerry(String) case windowsPhone(String) }

let iphone = MobilePhone.iphone("7 Plus")
