KODE SNIPPETS

Greetings!

So I wrote this function and then felt like sharing it with you guys.
Which basically helps you retrieve a Substring from an string.

Here is the function.

   
func getSubstring(mainString: String, startString: String,endString: String) -> String
        {
        var tempString = mainString.lowercaseString
        let start = tempString.rangeOfString(startString)
        let range = Range(start: tempString.startIndex, end: (start?.endIndex)!)
        tempString.removeRange(range)
            
        let substring = tempString.substringWithRange(Range(start: tempString.startIndex,end: (tempString.rangeOfString(endString)?.startIndex)!))
        return substring
        }

How it works?

You need to pass your whole string along with the string at -1th index of the starting index of your substring and the string at +1th index of the ending index of your substring. In return you’ll get your substring.

Check the result below:
