Answer 1

Mutable string of attributed string has functionality to find of range of specific string.

Try this and see (Swift 4):

let stringValue = "2/42"
let attributedString: NSMutableAttributedString = NSMutableAttributedString(string: stringValue)
let range: NSRange = attributedString.mutableString.range(of: "/42", options: .caseInsensitive)
print("range - \(range)")

Result:
range - {1, 3}
