Yes I got the answer as soon as I posted but no other StackOverflow question had the error before. Also, Google didn't work either. Thank you :) – deadcoder0904 Aug 24 '18 at 06:44

Whoops that was simple & I found the answer

First I did:

enum Coin {
    case heads = 0
    case tails
}

Just changed : to = but it threw error

Enum case cannot have a raw value if the enum does not have a raw type

So then I specified the type like:

enum Coin: Int {
    case heads = 0
    case tails
}

And voila it works
