Swift: 'Hashable.hashValue' is deprecated as a protocol requirement;
As the warning says, now you should implement the hash(into:) function instead.
func hash(into hasher: inout Hasher) { switch self { case .mention: hasher.combine(-1) case .hashtag: hasher.combine(-2) case .url: hasher.combine(-3) case .custom(let regex): hasher.combine(regex) // assuming regex is a string, that already conforms to hashable }}It would be even better (in case of enums and struct) to remove the custom hash(into:) implementation (unless you need a specific implementation) as the compiler will automatically synthesize it for you.
Just make your enum conforming to it:
public enum ActiveType: Hashable { case mention case hashtag case url case custom(pattern: String) var pattern: String { switch self { case .mention: return RegexParser.mentionPattern case .hashtag: return RegexParser.hashtagPattern case .url: return RegexParser.urlPattern case .custom(let regex): return regex } }}
