Simple types: Summary
You’ve made it to the end of the first part of this series, so let’s summarize.
- You make variables using
varand constants usinglet. It’s preferable to use constants as often as possible. - Strings start and end with double quotes, but if you want them to run across multiple lines you should use three sets of double quotes.
- Integers hold whole numbers, doubles hold fractional numbers, and booleans hold true or false.
- String interpolation allows you to create strings from other variables and constants, placing their values inside your string.
- Swift uses type inference to assign each variable or constant a type, but you can provide explicit types if you want.
