Description

There are several references to associated type in the Adopting a Protocol Using a Synthesized Implementation subsection. An enumeration doesn't have an associated type. Rather, some or all of its enumeration cases may have associated values.

Correction

Replace each instance of associated type with associated value. In some cases, the wording should be adjusted to indicate the types of the associated values for clarity.

Specifically, the last two bullets in the first list should become:

• Enumerations that have only associated values whose types conform to the Equatable protocol
• Enumerations that have no associated values

The last two bullets in the second list should become:

• Enumerations that have only associated values whose types conform to the Hashable protocol
• Enumerations that have no associated types

Finally, the second sentence in the seventh paragraph should be reworded to:

If the enumeration has associated values, their types must all conform to the Comparable protocol.
