Declare array of UIButtons

I want my swift code to create buttons using colors. I know I want to declare array but some of the things I have tried are not working. What I tried below is not working. I have tried to do various forms of wrapping but it did not work. The goal of this code is to not use any storyboards and do everything by code.

  var red,blue = UIButton()
Solution

  • One compact way to declare two variables in one line is to use tuple notation:

    let (red,blue) = (UIButton(), UIButton())

    Perhaps that's what you're asking for. But there is no array in the story; it's hard to see why you mention arrays in the first place.

    On the other hand, if you really do want an array as you claim, then it's hard to see what the names red and blue are for, since the elements of an array do not have names (with regard to the array). You could make an array of two new buttons by saying:

    let arrayOfTwoButtons = (0..<2).map {_ in UIButton()}
