你可以这样做：

//
// Play with finding substrings returning an array of the non-unique words and positions in text
//
//

import UIKit

let Bigstring = "Why is it so hard to find substrings in Swift3"
let searchStrs : Array<String>? = ["Why", "substrings", "Swift3"]

FindSubString(inputStr: Bigstring, subStrings: searchStrs)


func FindSubString(inputStr : String, subStrings: Array<String>?) ->    Array<(String, Int, Int)> {
    var resultArray : Array<(String, Int, Int)> = []
    for i: Int in 0...(subStrings?.count)!-1 {
        if inputStr.contains((subStrings?[i])!) {
            let range: Range<String.Index> = inputStr.range(of: subStrings![i])!
            let lPos = inputStr.distance(from: inputStr.startIndex, to: range.lowerBound)
            let uPos = inputStr.distance(from: inputStr.startIndex, to: range.upperBound)
            let element = ((subStrings?[i])! as String, lPos, uPos)
            resultArray.append(element)
        }
    }
    for words in resultArray {
        print(words)
    }
    return resultArray
}
