What are escape sequence characters in Swift?
Overview
Escape sequence characters are characters that do not represent themselves when used in a string. Rather, they tell the computer to perform a certain function or command. All escape sequences begin with an escape character.
Some escape sequence characters along with their description are given below:
\n: This is a newline character. It the computer to move to the next line.\t: This is a tab. It tells the computer to leave a tab.\r: This is the carriage return. It tells the computer to move the cursor to the starting of the line.\'or\": A single quote or double quote. This tells the computer to wrap a string or character with quotation marks.\\: A backward slash. This tells the computer to add a backward slash to a string.
Return value
The value these escape sequences return is a function telling the computer what to do.
Example
// use escape sequences in stringsprint("Welcome to\nEdpresso!"); // a new lineprint("Welcome to\tEdpresso!"); // a tabprint("Welcome to\rEdpresso!"); // a carriage returnprint("\"Welcome to Edpresso!\""); // a double quoteprint("\'Welcome to Edpresso!\'"); // a single quoteprint("\\Welcome to Edpresso!\\"); // a backward slash
