Swift uses backslash to escape double quotes. Here is the list of escaped special characters in Swift:
\0(null character)\\(backslash)\t(horizontal tab)\n(line feed)\r(carriage return)\"(double quote)\'(single quote)
This should work:
text2 = text2.replacingOccurrences(of: "\\", with: "", options: NSString.CompareOptions.literal, range: nil)
