Setting images of a button

I have come across an issue I cannot resolve.

I have a struct and would like to change the image of a button in each collection view. My text/image works as according to plan. However, when trying to change the image button I am struggling. Could someone please help me?

class CollectionViewContent{

    var caption = ""
    var mainImage: UIImage!
    var userProfileImage : UIButton


    init(caption: String, mainImage: UIImage!, userProfileImage : UIButton! )
    {
        self.description = description
        self.mainImage = featuredImage
        self.userProfileImage = postedUserProfileImage
    }


    static func  showPosts() -> [Posts]
    {
        return [
            Posts(description: "Sweet", mainImage: UIImage(named: "Image 1"), postedUserProfileImage:!),
                   Posts(description: "Awesome", mainImage: UIImage(named: "Image 2")!),
                   Posts(description: "WOW!", mainImage: UIImage(named: "Image 3")!

                  )
        ]
    }


}

This is my collectionViewCell class

class colViewContetCollectionViewCell: UICollectionViewCell {


    var posts: Posts! {
        didSet {
            updateUI()

        }
    }
    @IBOutlet weak var featuredImage: UIImageView!
    @IBOutlet weak var postCaptionLabel: UILabel!
     @IBOutlet weak var postedUserProfileImage: UIButton!



    func updateUI() {
        postCaptionLabel?.text! = posts.title
        featuredImage?.image! = posts.featuredImage
        postedUserProfileImage = posts.postedUserProfileImage
    }

    override func layoutSubviews() {
        super.layoutSubviews()

        self.layer.cornerRadius = 10.0
        self.clipsToBounds = true
    }

}

I think this line of code is incorrect by the way, I am not too sure.

 postedUserProfileImage = posts.postedUserProfileImage

Instead of:

postedUserProfileImage = posts.postedUserProfileImage

You should do:

postedUserProfileImage.setImage(posts.postedUserProfileImage.image(for: UIControlState.normal), for: UIControlState.normal)

Since postedUserProfileImage is a UIButton, you need to use the setImage method to set it's image for a control specific control state. If no images are set for the other control states, the image for the normal state is used for the others too.

And since posts.postedUserProfileImage is also a UIButton (as mentioned in the comments below) you need to get the button's image via the image(for:) method.
