Swift Higher Order Functions Filter, Map, Reduce, Flatmap and CompactMap

Map, filter, reduce, Flatmap and  CompactMap drop in Swift. Simple Higher Order Function Higher order functions are simply functions that operate on other functions by either taking a function or closures as an argument, or returning a function. That can be used on collection types such as Array or Dictionary Map : - " Use map to loop over a collection and apply the same operation to each element in the collection. The map function returns an array containing the results of applying a mapping or transform function to each item:" That used for-loop-  let arrays = [2.0,4.0,5.0,7.0] var arraySquar: [Double] = [] for value in arrays {   arraySquar.append(value*value) } // [4.0, 16.0, 25.0, 49.0] Now With map let arrays = [2.0,4.0,5.0,7.0] let arraySquar= arrays .map {$0 * $0} // [4.0, 16.0, 25.0, 49.0] let scores = [0,28,124] let words = scores.map { NumberFormatter.localizedString(from: $0 as NSNumber, number: .spellOut) } print(words) // ["ze

Nested JSON Parsing with Alamofire and SwiftyJSON in Swift 4

Build A Simple API (Custom JSON) with Alamofire & SwiftyJSON  This Full Example helps to design a UIViewController WithOut StoryBoard with a UITableViewController, Custom Cell design to show data ion to api service json, this Tutorial  helps to understand how to use Alamofire with SwiftyJSON to hit an API and fetch results, parse them and show the results in an UITableViewController. A Nested JSON :- like /*{ "id": "c200", "name": "Ravi Tamada", "email": "ravi@gmail.com", "address": "xx-xx-xxxx,x - street, x - country", "gender" : "male", "phone": {     "mobile": "+91 0000000000",     "home": "00 000000",     "office": "00 000000" } } */ Web Service api -   https://api.androidhive.info/contacts/  parse the data and show result in tableView. First create pod file instal
