“Challenge

Use two instances of NSDate to figure out how many seconds you have been alive.
First, NSDate has an instance method timeIntervalSinceDate:. This method takes one argument – another instance of NSDate. It returns the number of seconds between the NSDate that received the message and the NSDate that was passed in as the argument.
It looks something like this:
double secondsSinceEarlierDate = [laterDate timeIntervalSinceDate:earlierDate];
Second, you will need to create a new date object that is set to a given year, month, etc. You will do this with the help of an NSDateComponents object and an NSCalendar object. Here is an example:
NSDateComponents *comps = [[NSDateComponents alloc] init];
[comps setYear:1969];
[comps setMonth:4];

        NSDateComponents *comps = [[NSDateComponents alloc] init];
        [comps setDay:20];
        [comps setMonth:01];
        [comps setYear:1985];
        //[comps setTimeZone:<#(NSTimeZone *)#>];
        NSDate *now = [NSDate date];
        NSDate *birthday = [NSDate comps];
        
        double difference = [birthday timeIntervalSinceDate:now];

lfaoro

NSDate *now = [NSDate date];
        NSDateFormatter *format = [[NSDateFormatter alloc]init];
        [format setDateFormat:@"yyyy-MM-dd"];
        NSString *nowDate = [format stringFromDate:now];
        NSLog(@"test: %@",nowDate);
        NSDateComponents *comps = [[NSDateComponents alloc] init];
        [comps setDay:27];
        [comps setMonth:9];
        [comps setYear:1988];
        NSCalendar *local = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];

let letters = ["0", "a", "b", "c", "d", "e", "f", "g", "h"]
let numbers = ["0", "1","2","3","4","5","6","7","8"]

func position(column: Int, row: Int) -> String {
    if (column < letters.startIndex || column > letters.count) {
        return "The board accepts onlynumbers from 1 to 8"
    }else if (row < numbers.startIndex || row > numbers.count){
        return "The board accepts onlynumbers from 1 to 8"
    }
    var pieceAtColumn = letters[column]

I have all these cases that assign a lengthy subview repetitive code:
                case (1, 1), (1, 8):
                    var value = Piece(color: .w, shape: .R)
                    var pieceImg = NSImage(named: "wR")
                    var pieceView = NSImageView(frame: CGRect(x: squareX, y: squareY, width: cellLength, height: cellLength))
                    pieceView.image = pieceImg
                    boardView.addSubview(pieceView, positioned: .Above, relativeTo: nil)

What if I assign just the:
                    var value = Piece(color: .w, shape: .P)

lfaoro

import Cocoa
import Swift

enum Shape {
    case K, Q, B, R, N, P
    static let allValues = [K, Q, B, R, N, P]
}

enum Color {
    case w, b

lfaoro

enum Shape {
    case K, Q, B, R, N, P
    
    static let allValues = [K, Q, B, R, N, P]
}

enum Color {
    case w, b
    
    static let allValues = [w, b]

7) a function that lists all the pieces in the configuration of step 6
