Reading a single line of text from the console[edit]

Note: Input read from the console is terminated with a ^D (Control-D) which indicates the end-of-file.

Swift[edit]

// Read a single line of input from the console
let line = readLine()            // This will return an optional string
if line != nil {                 // Let's check if it's not nil, if so, it's really a string
    let text = line!             // Unwrap the string
    print("You typed: \(text)")  // Print the string
}
// Read a single line of input from the console (syntactic sugar)
if let text = readLine() {
    print("You typed: \(text)")
}
