Great job 🙌 We have learned about the power and flexibility offered by Swift enumerations. Here’s what we covered:
- What an enumeration is
- How to use enumerations in a switch control flow
- How to iterate over enumerations cases like a collection
- Defining raw values in an enumeration
- Explicitly and implicitly assigning raw values
- Extracting raw values for cases
- Initializing an instance with a raw value
- All cases must have the same type of raw value
- Defining associated values in an enumeration
- Associated values can be differently typed for each case
- All cases don’t need associated value
- Implementing methods in enumerations
- Use of mutating methods
- Defining computed properties in enumerations
Enumerations are indeed first class citizens in Swift and can help you write clean, expressive code 🛩
