How to eliminate a space character from a String?

Question

In my app I have a text field, and when the user presses a button the text he have entered is added to a label. The problem is that if the user add an space at the end, the txt of the label looks bad.

Text field: "Diego " Label: Great Diego !

Perform this on your String:

let trimmedString = yourstring.trimmingCharacters(in: .whitespacesAndNewlines)

It returns a new string made by removing from both ends of the String characters contained in a given character set, which in this case are whitesspaces and newlines. If you don't want to trim newlines, replace .whitespaceAndNewLines with .whitespace.

You can use String's trimming method passing in the characters to be trimmed. One way to do this is:

let string = "   something "
string.trimmingCharacters(in: .whitespacesAndNewlines)

Which will remove whitespace and newlines from the beginning and the end of the string.
