End to End encryption: Firestore and Swift

I want to add end to end encryption to my Firestore chat app. Since I am very new to this topic I would like to hear whether I got the fundamentals right – I would structure it like this:

Encryption: Sender generates a random AES-256 key and encrypts this with the public RSA key of the recipient. He also encrypts the message with the AES256 key. Furthermore he hashes the message and encrypts it with his private key for signing. Then he sends all of the information to the recipient.

The recipient decodes the AES key using his private RSA key and uses the decoded AES key to decrypt the message. He then hashes the message and decrypts the signature of the sender with the sender’s public RSA key. The last step is to compare the two hashes and see whether they are the same.

Did I get this concept right or is something wrong?

Minimum Area Rectangle in Swift

This is my solution to LeetCode – Minimum Area Rectangle in Swift

939. Minimum Area Rectangle

Given a set of points in the xy-plane, determine the minimum area of a rectangle formed from these points, with sides parallel to the x and y axes.
If there isn’t any rectangle, return 0.

  • Example 1:

Input: [[1,1],[1,3],[3,1],[3,3],[2,2]]

Output: 4

  • Example 2:

Input: [[1,1],[1,3],[3,1],[3,3],[4,1],[4,3]]

Output: 2

class Solution {     struct Point_Dng: Hashable{         var x: Int         var y: Int          init(_ x: Int, _ y: Int) {             self.x = x             self.y = y         }          var hashValue: Int{             return x * 100000 + y         }           static func == (_ lhs: Point_Dng, _ rhs: Point_Dng) -> Bool{             return lhs.x == rhs.x && lhs.y == rhs.y         }     }        func minAreaRect(_ points: [[Int]]) -> Int {         let points_new = points.map({ (point: [Int]) -> Point_Dng in             return Point_Dng(point[0], point[1])         })         let set = Set(points_new)         var ans = Int.max         for point in points{              for point_piece in points{                   if point[0] != point_piece[0] , point[1] != point_piece[1] , set.contains(Point_Dng(point[0], point_piece[1])) ,set.contains(Point_Dng(point_piece[0], point[1])) {                      ans = min(ans, abs((point_piece[1] - point[1] ) * (point_piece[0] - point[0])))                 }              }         }          if ans == Int.max {             return 0         }         else{             return ans         }      } } 

Note:

  1. 1 <= points.length <= 500

  2. 0 <= points[i][0] <= 40000

  3. 0 <= points[i][1] <= 40000

  4. All points are distinct.

According to LeetCode’s note, I improved the hash performance. I turned

var hashValue: Int{      return "\(x)\(y)".hashValue } 

into

var hashValue: Int{      return x * 100000 + y } 

because Swift’s tuple is not hashable. The prior one will lead to “Time Limit Exceeded”

How can I improve it further?
In fact I want to know is there something I missed in Swift.
Something out of my knowledge.
Because I did it simple.

Different web servers for Development and Production versions Swift

I am developing an app, which is using a web based database. I would like to separate the server addresses for the development builds and use this development server during the approval process when Apple is checking the App.

Once it is released, it should use the production server.

Could somebody help me where can I find how this can be made?

Playing Card in Swift

I’m trying to properly write a card class in swift. I’ve been taking classes in software engineering and I need help in understanding how to take a more object-oriented approach to my class. I have seen a Class for suit and rank and I’m wondering would that approach would be better? I have also seen the suit as enums and wonder if that approach would be better.

Any help will be appreciated.

Thank you

class Card
private var rank: Int private var suit: Int  init(n: Int) {     self.rank = -1;     self.suit = -1;     if(n >= 0 && n <= 51) {         self.rank = n % 13;         self.suit = n / 13;     } }  func getRank() -> Int {     return self.rank; }  func getSuit() -> Int {     return self.suit; }  func compareRank(otherCard: Card) -> Bool {     return self.rank == otherCard.getRank(); }  func compareSuit(otherCard: Card) -> Bool {     return self.suit == otherCard.getSuit(); } 

Swift 4 – Aplicación en MacOS

Buenas quiero hacer una aplicación en macOS muy simple, tipo “Hola mundo”. Una aplicación que constaría de dos ventanas (Vistas) abierta de forma simultáneas. En la primera ventana (vista) tendría un botón y una caja de texto (NSTextField) y en la segunda ventana (vista) solo aparecería la caja de texto. De forma que en tiempo real cada vez que haga un cambio en la primera ventana me lo actualice en la segunda. He estado buscando información pero no consigo dar con la tecla. Gracias.

Cuál sería el similar de un gridlayout de Android en Swift?

Ahora que estoy terminando de programar mi app en Android estoy buscando la forma de replicarla en Swift para IOS, sin embargo, las herramientas que use en Android no tienen el mismo nombre en Swift y creo que no hacen lo mismo…

¿Alguien tiene alguna idea de cuál herramienta se podría parecer a un GridLayout con varios cuadros y que además al clickear cada objeto en el GridLayout me redirija a distintos sitios?

Espero puedan ayudarme, desde ya, muchas gracias.
