10.5 Implementing Multiple Protocols
In Swift, protocol-supporting data types are free to implement multiple protocols. So long as all imposed properties and functions are implemented, there is no restriction against that. Figure 10.10 illustrates a sample architecture in which different classes implement different sets of protocols.
