Track random numbers

I want to apply images to 3 random UIButtons amongst my 12 UIButtons in total.

My idea to make it work;

I generate 3 random numbers between 1-12. Depending on the 3 random numbers I will use if-statements to interact with the different buttons. Example;

Code generates 3 random numbers that I hold in a variable: var numbers = (1, 2, 3)

Then I use an if-statement to check if the variable holds any number equal to 1

if numbers == 1 {
//code
}

Then make this same if-statement for all twelve of my buttons (if numbers == 2 | if numbers == 3 | if numbers == 4...) And so on. The problem is you can't do this if-statement.

Here is my try at making the example above;

var numbers = Array(0...12)

    numbers.shuffled()

    var pick3numbers = numbers.choose(3)

So far so good, it generates three random numbers kept in var pick3numbers now to my issue;

I want to make an if-statement depending on the random numbers kept in var pick3numbers. However, I can't make the if statement I want to; (example;)

*If any of the three* numbers == 1 {
self.button1.setImage(UIImage(named: "code2"), forState: .Normal)
}

Am I stepping in mud or can this actually be done somehow?
