In [[Swift]], strings can include emojis and other UTF-8 characters. ```swift let example = "This is an example of a string ⭐️" let longerExample = """ Multi-line strings use triple-quotes, just like Python! """ ``` Some useful string operations are: - Use `example.count` to get the length of a string. - Use `example.uppercased()` to get the string in upper-case letters. - Use `example.hasPrefix(prefix)` to check if a string starts with a value (same with `example.hasSuffix(suffix)`). ## String interpolation [[Swift]] allows for string interpolation using a pretty straightforward syntax: ```swift let name = "Diego" let age = 27 let message = "Right now, \(name) is \(age) years old." ```
