In c# or others we can use this in IF
ex.
if((a=1 && b=2)
(c=2 && d=3)
){}
using ( inside ( to check bool in that statement.
But in swift
I'm trying to make something like this.
func IsWorkDay() -> Bool {
if (monWorkYN == "Y" , weekday == 2)
|| (tueWorkYN == "Y" , weekday == 3)
|| (wedWorkYN == "Y" , weekday == 4)
{
return true
}
}
But the ( ) doesn't work here. Is there a way to do this?
In this case you have to use the && operator, with a comma the compiler treats the expression in parentheses as a tuple.
And please name functions (and variables) with starting lowercase letter
func isWorkDay() -> Bool {
if (monWorkYN == "Y" && weekday == 2)
|| (tueWorkYN == "Y" && weekday == 3)
|| (wedWorkYN == "Y" && weekday == 4)
{
return true
}
return false
}
or simpler
func isWorkDay() -> Bool {
return (monWorkYN == "Y" && weekday == 2)
|| (tueWorkYN == "Y" && weekday == 3)
|| (wedWorkYN == "Y" && weekday == 4)
}
You can use this property instead of your function
var isWorkDay: Bool {
return (monWorkYN == "Y" && weekday == 2)
|| (tueWorkYN == "Y" && weekday == 3)
|| (wedWorkYN == "Y" && weekday == 4)
}

is it becase i have too too many functions? right now myconcern is with create only.
is it becasue the id doesnt have security rule to validate? i tried providing validation for id as well but the error still persist. i need more than 10 map in an array but this is for simplicity of testing process.

Below is some code to check if somebody has won on a tic tac toe board. (board[0] - board[8] represent the tic tac toe board from top to bottom, left to right):
func checkWin(board: [Int]) -> Bool{
if board[0] != 0 {
if board[0] == board[1] && board[1] == board[2] {
return true
} else if board[0] == board[3] && board[3] == board[6] {
return true
}
} else if board[4] != 0 {
if board[1] == board[4] && board[4] == board[7] {
return true
} else if board[3] == board[4] && board[4] == board[5] {
return true
} else if board[2] == board[4] && board[4] == board[6] {
return true
} else if board[0] == board[4] && board[4] == board[8] { //
return true
}
} else if board[8] != 0 {
if board[2] == board[5] && board[5] == board[8] { //
return true
} else if board[6] == board[7] && board[7] == board[8] { //
return true
}
}
return false
}
However, the three lines with // at the end will not return true even if the conditions are met. I have noticed that they all share board[8], however I know this is not a problem with the storyboard, as if I hard code a win that satisfies one of faulty conditions it still doesn't work. Can anyone see what's going wrong?
Your logic is flawed. Once you check with the outer ifs, you have committed to just checking a few of the possible cases.
For instance, if space 0 is not empty, then you are only checking cases 0-1-2 and 0-3-6, but you aren't checking 0-4-8 so you'll miss that possibility. The 0-4-8 case is handled inside the first else if case, but you'll never get there if board[0] != 0.
You can fix this by using 3 ifs instead of the else ifs.
func checkWin(board: [Int]) -> Bool{
print(board)
if board[0] != 0 {
if board[0] == board[1] && board[1] == board[2] {
return true
} else if board[0] == board[3] && board[3] == board[6] {
return true
}
}
if board[4] != 0 {
if board[1] == board[4] && board[4] == board[7] {
return true
} else if board[3] == board[4] && board[4] == board[5] {
return true
} else if board[2] == board[4] && board[4] == board[6] {
return true
} else if board[0] == board[4] && board[4] == board[8] { //
return true
}
}
if board[8] != 0 {
if board[2] == board[5] && board[5] == board[8] { //
return true
} else if board[6] == board[7] && board[7] == board[8] { //
return true
}
}
return false
}
a little bit more compact:
func checkWin(board: [Int]) -> Bool{
let checks = [
//rows
[0,1,2],
[3,4,5],
[6,7,8],
//columns
[0,3,6],
[1,4,7],
[2,5,8],
//cross
[0,4,8],
[2,4,6]
]
for check in checks{
if board[check[0]] != 0
&& board[check[0]] == board[check[1]]
&& board[check[1]] == board[check[2]]
{
return true
}
}
return false
}
better to get also the winner-id or 0 for no winner:
func getWinner(board: [Int]) -> Int{
let checks = [
//rows
[0,1,2],
[3,4,5],
[6,7,8],
//columns
[0,3,6],
[1,4,7],
[2,5,8],
//cross
[0,4,8],
[2,4,6]
]
for check in checks{
if board[check[0]] != 0
&& board[check[0]] == board[check[1]]
&& board[check[1]] == board[check[2]]
{
return board[check[0]]
}
}
return 0
}
or if you like to put it in an enum:
enum Winner {
case none
case player(id: Int)
}
func checkWin(board: [Int]) -> Winner{
let checks = [
//rows
[0,1,2],
[3,4,5],
[6,7,8],
//columns
[0,3,6],
[1,4,7],
[2,5,8],
//cross
[0,4,8],
[2,4,6]
]
for check in checks{
if board[check[0]] != 0
&& board[check[0]] == board[check[1]]
&& board[check[1]] == board[check[2]]
{
return .player(id: board[check[0]])
}
}
return .none
}
I am wanting to compare three randomly generated numbers to see if any two of them are equal. I have an if statement that works but I would really like to combine the two else if statements into one if possible. I am thinking there has to be some way to use or but its only a binary operator. is there a way to use ? and make a ternary argument in one else if statement?
if aRand == bRand && bRand == cRand{
resultLabel.text = "3 out of 3"
} else if
(aRand == bRand || aRand == cRand) {
resultLabel.text = "2 out of 3"
} else if
(bRand == cRand) {
resultLabel.text = "2 out of 3"
} else {
resultLabel.text = "No Match"
}
Actually it's
if aRand == bRand || aRand == cRand || bRand == cRand
Here a swiftier expression
let rand = (aRand, bRand, cRand)
switch rand {
case let (a, b, c) where a == b && b == c : resultLabel.text = "3 out of 3"
case let (a, b, c) where a == b || a == c || b == c : resultLabel.text = "2 out of 3"
default : resultLabel.text = "No match"
}
Shorter way:
if (aRand == bRand && bRand == cRand) {
resultLabel.text = "3 out of 3"
} else if (aRand == bRand || bRand == cRand || aRand == cRand) {
resultLabel.text = "2 out of 3"
} else {
resultLabel.text = "No Match"
}
If I understand your algorithm correctly, you can avoid if altogether:
let aRand = 0
let bRand = 1
let cRand = 1
let allValues = [aRand, bRand, cRand]
let uniqueValues = Set(allValues)
let text: String
if (uniqueValues.count == allValues.count) {
text = "No match"
} else {
text = String(format: "%i out of %i", allValues.count - uniqueValues.count + 1, allValues.count)
}
print(text)
This will work for any number of values.
I just updated to the non beta version of Xcode 6 (finally) and, coming from beta 5, got a few errors that I didn't get before, one being "could not find overload for '&&' that accepts the supplied arguments"
I am following a tutorial here and from another question, I know that this error is because "the expression was too complex to be solved in reasonable time; consider breaking up the expression into distinct sub-expressions."
I'm a beginner; how do I break up an expression into sub-expressions?
My code:
func checkForWin(){
//first row across
var youWin = 1
var theyWin = 0
var whoWon = ["Lost":0,"Won":1]
for (key,value) in whoWon {
if ((plays[6] == value && plays[7] == value && plays[8] == value) || //across the bottom
(plays[3] == value && plays[4] == value && plays[5] == value) || //across the middle
(plays[0] == value && plays[1] == value && plays[2] == value) || //across the top
(plays[6] == value && plays[3] == value && plays[0] == value) || //down the left side
(plays[7] == value && plays[4] == value && plays[1] == value) || //down the middle
(plays[8] == value && plays[5] == value && plays[2] == value) || //down the right side
(plays[6] == value && plays[4] == value && plays[2] == value) || //diagonal
(plays[8] == value && plays[4] == value && plays[0] == value)){//diagonal
userMessage.hidden = false
youLabel.hidden = false
userMessage.text = "\(key)!"
done = true;
}
}
}
To break it up, you just need to add more ()s. Like this:
if (((plays[6] == value) && (plays[7] == value) && (plays[8] == value)) ||
((plays[3] == value) && (plays[4] == value) && (plays[5] == value)) ||
((plays[0] == value) && (plays[1] == value) && (plays[2] == value)) ||
((plays[8] == value) && (plays[4] == value) && (plays[0] == value)))
