What is string concatenation in swift language
By adding the second string to the right-hand end of the first string, the concatenation operators merge two strings into one. Concatenation can happen with or without a blank in between. Concatenation is the process of combining two strings together, and the symbol for concatenation in many programming languages is a plus ( + ). When you want to display a message that includes the value of a variable, you can use concatenation.
