Get index of string in an array of NSAttributedString in swift - swift

Question

I have an array of NSattributedstring. I want to get the index of a string in the array. I am using the following code.
let textToSearch = "My name is Amrit"
let index = find(myArray, textToSearch)
myArray is an array of NsattributedString. As both the types of array and textTosearch are different.
indexArray = ["1. THE OPENING","2. THE COW","3. THE FAMILY OF IMRAN","4. WOMEN","5. THE FEAST","6. LIVESTOCK","7. THE HEIGHTS","8. BATTLE GAINS","9. REPENTANCE","10. JONAH","11. HUD","12.

Answer 1

You can try this:
let index = myArray.indexOf { $0.string == textToSearch }
This returns an Int?, the first index where a match is found. If there's no match, it will return nil.

Answer 2

If you are using Swift 1.2 you will need to map array of NSAttributedString to String array so find function can be called with correct values
let index = find(myArray.map({ attributedString in
return attributedString.string
}), textToSearch)
