Why am I getting 'is not a valid digit in integer literal' error while naming Swift enum case?












1














I'm trying to create an enum with running distances, but Swift is not letting me name the enum case with in this format 5K. I get an error saying 'K' is not a valid digit in integer literal. Here is my code: code

Identifiers and hence type properties/enum cases cannot start with numbers. You need to change the naming convention for your enum.



enum RaceType: String {

    case fiveK = "5K"

    case tenK = "10K"

    case marathon

}

    It's not obvious that enum cases have anything to do with variables. Use identifiers to cover all those cases without implying a stronger relationship between them.

Quarantine

For other uses, see Quarantine (disambiguation). Signal flag "Lima" called the "Yellow Jack" which when flown in harbor means ship is under quarantine. A simple yellow flag (also called the "Yellow Jack") had historically been used to signal quarantine (it stands for Q among signal flags), but now indicates the opposite, as a signal of a ship free of disease that requests boarding and inspection. A quarantine is used to separate and restrict the movement of people; it is 'a restraint upon the activities or communication of persons or the transport of goods designed to prevent the spread of disease or pests', for a certain period of time.
