Learn how to design the same system using POP.
- [Instructor] Now let's redesign our UI components…using a protocol oriented approach.…We start with defining our protocols first.…We're going to create dedicated protocols for…each feature set.…As a quick remark, we're going to follow…the swift naming guidelines.…Regarding protocol names, the rules are clear.…Protocols that describe what something is…should read as nouns.…For example collection.…Protocols that describe a capability should…be names using the suffixes able, ible, or ing.…
Like equatable or progress reporting.…Since our protocols describe capabilities,…we're going to use the second form.…Alright let's open up xcode and create a…playground project.…We need a playground.…Blank project is good.…And I'm going to call it protocol way.…Let's remove the unnecessary stuff.…
So let's create our first protocol.…I'm going to call it animatable.…It declares the only animation related…method that we're going to use.…That is called pulse.…It takes a duration argument of type time interval.…Next I provide the default implementation…
