Join Károly Nyisztor for an in-depth discussion in this video Adopting a protocol, part of Swift 4: Protocol-Oriented Programming.
- [Narrator] If we wish…to create the time conforming to increment protocol,…we must declare and define…the matching properties and methods.…So let's create the structured called TaggedData.…It is going to adopt the Binary Representable Protocol…but it doesn't conform to the protocol yet.…Autocomplete can add the missing stops for us.…So let's do that.…The stops have no increment data showing yet,…so let's adjust some code.…
I'm going to return false for now.…The Increment Counter should increment the counter's value.…Next I am going to implement the initializer.…So let's initialize our tag…and data properties.…Equals data.…Alright now…I have to provide the default value…for the static counter instance.…Let's initialize it to zero,…and the code should compile just fine.…
