How to make computer generate predefined set of numbers in Swift? - ios

Question

I want to make the computer generate predefined set of numbers one-by-one. How is it possible in Swift? Is it possible using arrays?
For example: I want to generate [1,2,3,4] in that same order one-by-one. By generate I mean to show up like how random numbers show up when you type in arcrandom_uniform().
Example:
var randomNumber = [1,2,3,4,5]
var guessInt = guess.text.toInt()
Then when I type ..
if Int(randomNumber) == guessInt {
//conditions
}
The error shows as : Cannot assgn to the result of ths expresson
Sometimes I get the error as Int' is not convertible to '[Int]' swift
The code won't work! Help ?
Here's the code for #David Skrundz :
` #IBAction func guessButton(sender: AnyObject) {
var randomNumber = [1,2,3,4,7,8,9,5]
var guessInt = guess.text.toInt()
func generator() -> () -> Int {
var currentIndex = 0
let array = Array(1...5)
func generate() -> Int {
let value = array[currentIndex++]
if currentIndex >= array.count {
currentIndex = 0
}
return value
}
return generate
}
let gen = generator()
gen() // Returns 1
gen() // Returns 2
gen() // Returns 3
gen() // Returns 4
gen() // Returns 1
let answer = gen()
if answer == guessInt {
resultLabel.text = "Bingoo..! "}
else {
resultLabel.text = "Oh such a bad guesser! It was a \(answer)"
}
println(answer)
}
`
Any idea how to fix this code the problem mentioned below ! ? Please !

Answer 1

You may want the range operator:
for index in 1...5 {
println("\(index)")
}

Answer 2

If you want to generate the next element in a repeating sequence, you could use
func generator() -> () -> Int {
var currentIndex = 0
let array = Array(1...4)
func generate() -> Int {
let value = array[currentIndex++]
if currentIndex >= array.count {
currentIndex = 0
}
return value
}
return generate
}
And to use it:
let gen = generator()
gen() // Returns 1
gen() // Returns 2
gen() // Returns 3
gen() // Returns 4
gen() // Returns 1
