In Swift, strings can include emojis and other UTF-8 characters.

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:

let name = "Diego"
let age = 27
 
let message = "Right now, \(name) is \(age) years old."
