Top 4 Swift 4 Updates that has Made the Developer’s Job Easy.

Swift 4- New updates
After the introduction of NodeJS, there has been no such launch that would fascinate the developers’ fraternity, until the recent launch of Swift 4. The popularity of iOS platforms has shift people’s attention to Swift 4. Swift 3, introduced last September, made its impact and drove people away from Objective C, a development language Apple traditionally used. Moreover, Swift displayed the potential to make iOS programming easier for the developers and user-friendly.

What updates did Swift 4 bring on the table for the developers?

  Swift-4  

1. String processing is more robust

String based data processing feature has always got Apple’s attention. C# has been a master in string processing for years. However, Apple is redirecting this title towards Swift because of its robust nature. Major benefits of Swift 4 are:
  1. Well directed string operations
  2. Shorter development time
  3. Ability to troubleshoot string processing problems using its native API rather than writing custom codes
let bexcodeString = "BexCode Services"
for bxcd in bexcodeString {
print(bxcd)
}

2. String as collections

Well! The collection of String functions is always a handy option for operations such as sorting. Swift 4 offers this handy option.
let allAlphabets = "A Quick Brown Fox Jumps Over The Lazy Dog"
let reversed = allAlphabets.reversed()

3. Dictionary and Sets improvements

Two most critical data structures, Dictionary and Sets, have received a lot of attention. Swift 4 has made sure that performance intensive array operations can be replaced with dictionaries. In addition, the dictionaries are also made blazing fast to achieve fewer iterations on generic implementations.
let daySales =  [("Monday", 3900),  ("Tuesday", 5350),  ("Wednesday", 2948),  ("Thursday", 3135),  ("Friday", 7509),  ("Saturday", 8868),  ("Sunday", 8015)]
let compositeDictionary = Dictionary(uniqueKeysWithValues: daySales)
 
let Sales =  [3900,5350,2948,3135,7509,8868,8015]
let Days =  ["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"]
let compositeDictionary = Dictionary(uniqueKeysWithValues: zip(Days, Sales))

4. Swifty JSON operations

Since the launch of Swift 2, it was imperative to improve the JSON operations. Swift 4 evolved the programming language beyond expectation. Swifty JSON operations look like this:
struct Softwares: Codable {
var name: String
var version: Int
}
let Office = Softwares(name: "MS Office", version: 2013)
let Adobe = Softwares(name: "Adobe Photoshop", version: 11)
let Sony = Softwares(name: "Sony Soundforge", version: 2012)
  Here is how you can Serialize the object “Adobe” to JSON parsable string?  
let encoder = JSONEncoder()
if let encoded = try? encoder.encode(Adobe) {
// And we got JSON `encoded` here
}
Here is how you can convert a JSON string into an object?  
struct Schedule {
// ...
init?(json: [String: Any]) {
guard let title = json["title"] as? String,
let id = json["id"] as? Int,
let userId = json["userId"] as? Int,
let completed = json["completed"] as? Int else {
return nil
}
self.title = title
self.userId = userId
self.completed = completed
self.id = id
}
}
  Here is how you parse a JSON string for a single object conversion?
let todo = try decoder.decode(Schedule.self, from: responseData)
Swiftly JSON operations are simple and easy and API optimized. Swift 4 has made sure that the expectations of the developer fraternity is met and is met well. Swift 4 certainly looks promising. In the age of mobile software revolution, Swift 4 has made a great head start with some impressive performance improvements. We at BexCode, are looking forward to adopting Swift 4.
