Could not find member 'subscript'

I got this error message in Home.swift

override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(Bool())

        let scale = CGAffineTransformMakeScale(0.5, 0.5)
        let translate = CGAffineTransformMakeTranslation(0, -200)
        dialogView.transform = CGAffineTransformConcat(scale, translate)

        spring(0.5) {
            let scale = CGAffineTransformMakeScale(1, 1)
            let translate = CGAffineTransformMakeTranslation(0, 0)
            self.dialogView.transform = CGAffineTransformConcat(scale, translate)
        }

        avatarImageView.image = UIImage(named: data[number]["avatar"]!)
        imageButton.setImage(UIImage(named: data[number]["image"!]), forState: UIControlState.Normal) //error message here
        backgroundImageView.image = UIImage(named: data[number]["image"]!)
        authorLabel.text = data[number]["author"]
        titleLabel.text = data[number]["title"]

        dialogView.alpha = 1
    }

[loop]

This might be due to the fact that this app was built when Swift was still in developer mode. Some API functionality might have changed. I will have a look at this soon.
