Swift Strings

In Swift, Strings are used to store words, letters, or full sentences. Think of them as a container for readable text.

Wrap your text inside double quotes to craft a string in Swift.

let greeting = "Hello, Swift!"

Here, greeting holds a sequence of characters.

let first = "Hello" 
let second = "World" 
Let combined = first + " " + second  // "Hello World"

let name = "Alex" 
Let message = "Hi, \(name)!"  // "Hi, Alex!"

let word = "Swift" 
Print(word.count)  // 5

print(word.uppercased())  // "SWIFT" 
Print(word.lowercased())  // "swift"
