I want to find the nsrange of the the word which is repeating in the string ,it search should be case sensitive .

for example :

the main string is let str = "Hi satheesh how are you doing ,Hellow satheesh1 did you find the answer for satheesh".

now I want to find the ranges of word "satheesh" ..expected nsrange count should be 2 .i.e [nsrange(location : 3, lenght : 8),[nsrange(other word satheesh)] it should not take the range of satheesh1 because satheesh != satheesh1 .

I am using below code

extension String {
func ranges(of substring: String, options: CompareOptions = [], locale: Locale? = nil) -> [Range<Index>] {
    var ranges: [Range<Index>] = []
    while let range = self.range(of: substring, options: options, range: (ranges.last?.upperBound ?? self.startIndex)..<self.endIndex, locale: locale) {
        ranges.append(range)
    }
    return ranges
}
}

but the problem with this code is when finding the range it considering satheesh == satheesh1 so I am getting the ranges of satheesh and satheesh.

Can some one help me out to solve this problem

What happens if the string is like this "hi satheesh." Ending in a fullstop? – Rakesha Shastri Dec 08 '18 at 18:36
@RakeshaShastri it end up with space – Satheeshkumar Naidu Dec 08 '18 at 18:38
Should it be counted or not? – Rakesha Shastri Dec 08 '18 at 18:38
not required only range of all satheesh in string but it should not take the range of satheesh1 – Satheeshkumar Naidu Dec 08 '18 at 18:41
The word “you” is also repeated in your example sentence, should it be taken into consideration? – ielyamani Dec 08 '18 at 18:53
@Carpsen90 no i will have one search string for example satheesh ,only range of satheesh it should consider – Satheeshkumar Naidu Dec 08 '18 at 18:56
