struct AnyIndex A wrapper over an underlying index that hides the specific underlying type. See Also: AnyCollection Inheritance Comparable, Equatable View Protocol Hierarchy → Import import Swift Initializers init(_:) Creates a new index wrapping base. Declaration init<BaseIndex : Comparable>(_ base: BaseIndex) Instance Methods func <(_:rhs:) Returns a Boolean value indicating whether the first argument represents a position before the second argument. The types of the two underlying indices must be identical. Parameters: lhs: An index to compare. rhs: Another index to compare. Declaration func <(lhs: AnyIndex, rhs: AnyIndex) -> Bool func ==(_:rhs:) Returns a Boolean value indicating whether two indices wrap equal underlying indices. The types of the two underlying indices must be identical. Parameters: lhs: An index to compare. rhs: Another index to compare. Declaration func ==(lhs: AnyIndex, rhs: AnyIndex) -> Bool
