var xo = [String]()

var xo1 = ["x" , "10" ,"10" ,"10","10" ]

var xo2 = ["10 " , "x" ,"10" ,"10" ,"10" ]

var xo3 = ["10 " , "10" ,"x" ,"10" ,"10" ]

var xo4 = ["10 " , "10" ,"10" ,"x" ,"10"]

var xo5 = ["10 " , "10" ,"10" ,"10" ,"x" ]

xo.append(contentsOf: xo1)

xo.append(contentsOf: xo2)

xo.append(contentsOf: xo3)

xo.append(contentsOf: xo4)

xo.append(contentsOf: xo5)

//for _ in xo {

// print(xo)

//}

func xos (item: Int , count:Int ) -> [String] {

let xo8 = Array(repeating: item, count: count)

let xo9 = Array(repeating: item, count: count)

}

xos(item: xo, count: 1)

whats wrong ? how i can print like this :
[X, 0, 0, 0, 0]
[0, X, 0, 0, 0]
[0, 0, X, 0, 0]
[0, 0, 0, X, 0]
[0, 0, 0, 0, X]

Your answers are absolutely confusing.

If you want a matrix in x0, declare

Code Block var matrix = [[String]]()     // Array of Arrays ; changed the name to be more meaningful

and populate as follows:

Code Block var xo1 = ["x",  "10","10","10","10"]
var xo2 = ["10 ","x", "10","10","10"]
var xo3 = ["10 ","10","x" ,"10","10"]
var xo4 = ["10 ","10","10","x" ,"10"]
var xo5 = ["10 ","10","10","10","x"]
matrix.append(xo1)
matrix.append(xo2)
matrix.append(xo3)
matrix.append(xo4)
matrix.append(xo5)

Then with

Code Block print(matrix)

you get

[["x", "10", "10", "10", "10"], ["10 ", "x", "10", "10", "10"], ["10 ", "10", "x", "10", "10"], ["10 ", "10", "10", "x", "10"], ["10 ", "10", "10", "10", "x"]]

Or with:

Code Block for row in matrix {
    print(row)
}

you get

["x", "10", "10", "10", "10"]
["10 ", "x", "10", "10", "10"]
["10 ", "10", "x", "10", "10"]
["10 ", "10", "10", "x", "10"]
["10 ", "10", "10", "10", "x"]

Is it what you are looking for ?

Your function xos(item:count:) takes Int for item:.

Your function call xos(item: xo, count: 1) is passing an Array (not Int) to item:.

What sort of function do you want to write? A function taking Int and Int? Or a function taking Array and Int?

[X, 0, 0, 0, 0]
[0, X, 0, 0, 0]
[0, 0, X, 0, 0]
[0, 0, 0, X, 0] i want to write this, so string and int

Answer 3

OOPer OP

i want to write this,

Do you just want to write? No need to create an Array?

so string and int

What will be the values of the String and Int for the example output:

Code Block [X, 0, 0, 0, 0]
[0, X, 0, 0, 0]
[0, 0, X, 0, 0]
[0, 0, 0, X, 0]

The String value would be "X"? The Int value might be 4 (number of rows)? Or 5 (number of items in a row)? Or 0 (the value for non-X elements)? Or 20 (total number of items)?

Or something else?

Your question is not very clear.

Do you want to print (where ?) or do you want to display the matrix on screen in a Label, TextField, TextView ?

To print in log, simply do:

Code Block for x in xo {
  print(x)
}

i want to make a function with array

So, you want to define a function taking Array and Int. OK?

And you have not answered to my other questions.

Do you just want to write? No need to create an Array?
What will be the values of the Array and Int for the example output:

Please clarify all the things needed to write a function.
