Modify Object in Array with Swift?

Question

I have array:

var arrDicContact = udContact.valueForKey(\"arrDicContact\") as [NSDictionary]

and i want to change one contact in array:

Answer 1

Assuming we have the array like this:

var array:[NSDictionary] = [["name":"foo"],["name":"bar"],["name":"baz"]]

Using enumerate

for (idx, dic) in enumerate(array) {
    if (dic["name"] as? String) == "bar" {
        array[idx] = ["name": "newBar"]
    }
}

Iterate over indices:

for idx in indices(array) {
    if (array[idx]["name"] as? String) == "bar" {
        array[idx] = ["name": "newBar"]
    }
}

More aggressively, replace whole array using map:

array = array.map { dic in
    if (dic["name"] as? String) == "bar" {
        return ["name": "newBar"]
    }
    return dic
}
