how to add ~ and | in a character variable in swift?

Question

Swift produce an error when I'm try to compare ~ (tilde) or | (pipe) with a character in NSString object

Communicator.swift:63:48: Invalid character in source file and many other places

In your case, you should use something like ``Character(UnicodeScalar(data.characterAtIndex(0))) == "~"`` — Werner Kvalem Vesterås, Jan 07 '16 at 08:16
@Werner Kvalem Vesterås this question is not duplicate of any other the main problem with tilde ~ m know well how to compare 2 things — Indrajit Sinh Rayjada, Jan 07 '16 at 08:54
This is not Java, swift doesn't use single quotes for characters. That's why you have errors `Invalid character in source file`. There is no problem with tildes. — Sulthan, Jan 07 '16 at 09:18

@IndrajitSinhRayjada Your screenshot is showing a clear problem with single quotes. — Sulthan, Jan 07 '16 at 10:12

I have found the answer myself, just change following

String(UnicodeScalar(data.characterAtIndex(0))) == "~"
