convert array of strings to enums

strings_to_enums.swift

extension Array where Element == String {
    public func to_enums<T: RawRepresentable>() -> [T] where T.RawValue == String {
        let wrapped: [T?] = self.map { T(rawValue: $0) }
        return wrapped.filter { $0 != nil } as! [T]
    }
}

extension Array where Element == String {
    public func to_enums<T: RawRepresentable>() -> [T] where T.RawValue == String {
        let wrapped: [T] = self.compactMap { T(rawValue: $0) }
        return wrapped
    }
}

Then no more filter neither force casting
