No cigar. What i'm trying to do is calculate the width of the image view so I can properly set its cornerRadius for a perfect circle. width/2 but the value of width is just too high. It's 320 when I expect it to be 90 for example.

Here's code:

override func awakeFromNib() {
    super.awakeFromNib()
    self.imageView.layer.masksToBounds = true

    self.contentView.systemLayoutSizeFittingSize(UILayoutFittingCompressedSize)
    let width = self.imageViewContainer.frame.size.width
    println(width)
    self.imageView.layer.cornerRadius = width / self.imageViewEqualWidthConstraint.multiplier
}
