How to access data in CoreData using index of data?

Your result is array and each object in array is dictionary so basically which index you are talking about? — Annie Gupta

Your result is type of Array so you can access the object from result like result[0] and so on.

if index < result.count {
    let obj = result[index]
}

If you want index from object, you can use index(of:) for that.

if let index = result.index(of: obj) {
    print(index)
}
