USING ISWIFF HOW TO
To learn how to create command line tools, visit Command Line Tool on macOS. Note: The above program only runs if you have created a command line tool in Xcode. To learn more about optional, visit Swift Optionals. Hence, we have used name! to forcefully unwrap the name. The readLine() function doesn't return a regular string.

Here, the readLine() takes input from the user and assigns it to the name variable. ISwiff use the same Flash plugin as Safari in a stand alone app to let you open SWF files directly. In the above example, we are asking users to input values. Your favorite programming language is Swift. Output Enter your favorite programming language: Print("Your favorite programming language is \(name!).") However, we can create a Command line Tool in Xcode and use the readLine() function to take input from users.įor example, print("Enter your favorite programming language:") In Swift, we cannot directly take input from the Xcode playground. Hence, we get the output: "Swift was introduced in 2014". Now, the print() statement takes the value of the variable year and joins it with the string. In the above example, the string inside the print() statement includes Here, we use the backslash and bracket to print variables inside a string. In Swift, we can print a string and variable together by using string interpolation. To learn more about joining strings, visit Swift Join String. the print() function prints the joined string.the + operator joins two strings "Programiz is " and "awesome.".For example, print("Programiz is " + "awesome.") We can also join two strings together inside a print() statement. We can also use the print() function to print Swift variables. Hence, the output includes items separated by. Notice that we have used the optional parameter separator: ". In the above example, the print() statement includes multiple items separated by a comma. Hence, we get the output in a single line separated by space.Įxample 3: print() with separator print("New Year", 2022, "See you soon!", separator: ". Notice that we have included the terminator: " " after the end of the first print() statement. So we get the output in two different lines.Įxample 2: print() with terminator // print with terminator space Here, the value for terminator is not used. In the above example, the print() statement only includes the items to be printed. If we don't include them inside the print(), their default values: single space " " for separator and new line "\n" for terminator are used.Įxample 1: Swift Print Statement print("Good Morning!") Note: separator and terminator are optional. terminator (optional) - allows us to add add specific values like new line "\n", tab "\t".separator (optional) - allows us to separate multiple items inside print().
items - values inside the double quotation.
However, the actual syntax of the print function accepts 3 parameters print(items: separator: terminator:) In the above code, the print() function is taking a single parameter.
Here, the print() function displays the string enclosed inside the double quotation. In Swift, we can simply use the print() function to print output.
