Swift Language Strings and Characters Remove leading and trailing WhiteSpace and NewLine
Example
3.0
let someString = " Swift Language \n"
let trimmedString = someString.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceAndNewlineCharacterSet())
// "Swift Language"
Method stringByTrimmingCharactersInSet returns a new string made by removing from both ends of the String characters contained in a given character set.
We can also just remove only whitespace or newline.
Removing only whitespace:
let trimmedWhiteSpace = someString.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())
// "Swift Language \n"
Removing only newline:
let trimmedNewLine = someString.stringByTrimmingCharactersInSet(NSCharacterSet.newlineCharacterSet())
// " Swift Language "
3.0
let someString = " Swift Language \n"
let trimmedString = someString.trimmingCharacters(in: .whitespacesAndNewlines)
// "Swift Language"
let trimmedWhiteSpace = someString.trimmingCharacters(in: .whitespaces)
// "Swift Language \n"
let trimmedNewLine = someString.trimmingCharacters(in: .newlines)
// " Swift Language "
