SwiftyNSDictionary

SwiftyNSDictionary is a library that can help you convert values stored in a NSDictionary into non-objective-c types safely. As we all know that Objective C containers such as NSArray,NSDictionary cannot store non-object types. Because of this the evil NSNull borns which causes lots of chaos. This library is to help get values safely without considering Objective-C types.

About

• It requires minimum swift version is 3.0.
• Issues are welcomed.

Usage

We have functions that get values stored for a key: String, and cast to types which are widely used safely.

All those functions are in the form of:

func valueAs${Type}(forKey: String) -> ${Type}?

Let's see how to use

import SwiftyNSDictionary

let dict: NSDictionary = ["1": [1,2,3,4,[5,6,7]],
                          "2": ["2.1":[1,2,3],
                                "2.2":2.2, 
                               ],
                          "3": NSNull()]
let x = dict.valueAsInt(forKey: "1")
let arr = dict.valueAsArray(forKey: "1")
let dic = dict.valueAsDictionary(forKey: "2")
