how we find and replace array dictionary value in swift 3 - swift3

Question

My array has this dictionary I want to find and replace where dictionary h
attendance = "" and attendance = "A" and replace with attendance = "P"
I am using this:
checkedArray = [[String : AnyObject]]()
let index = find(checkedArray) { $0["attendance"] == "P" }
if let index = index {
checkedArray[index] = newDictionary
}
// Do any additional setup after loading the view.
}
func find<C: CollectionType>(collection: C, predicate: (C.Generator.Element) -> Bool) -> C.Index? {
for index in collection.startIndex ..< collection.endIndex {
if predicate(collection[index]) {
return index
}
}
return nil
}

{"studentID":"12","name":"panky","roll":"","attendance":"P"},
{"studentID":"14","name":"a","roll":"","attendance":""},
{"studentID":"4","name":"akshay","roll":"1","attendance":"E"},
{"studentID":"6","name":"anki","roll":"11","attendance":"P"},

Answer 1

let dic: [[String : Any]] = [
["studentID":"12","name":"panky","roll":"","attendance":"P"],
["studentID":"14","name":"a","roll":"","attendance":""],
["studentID":"4","name":"akshay","roll":"1","attendance":"E"],
["studentID":"6","name":"anki","roll":"11","attendance":"P"],
["studentID":"1","name":"mohit","roll":"2","attendance":"M"],
["studentID":"5","name":"yogi","roll":"22","attendance":"L"],
["studentID":"3","name":"Neha","roll":"3","attendance":"A"]
]
let result : [Any] = dic.map { dictionary in
var dict = dictionary
if let attendance = dict["attendance"] as? String, attendance == "" || attendance == "A" {
dict["attendance"] = "P"
}
return dict
}
