Rounding views with Auto Layout?

I want to create circular views when using Auto Layout, due to this, I can't set specific radius values in my view.

I thought I had resolved this with the following code, but it doesn't execute on the view's first load for some reason and the view appears square until I push the view of the screen and bring it back (for example raising the keyboard and lowering it). Any idea why or how I can approach a fix?

 override func viewWillLayoutSubviews() {
    self.myProfileView.userImage.layer.cornerRadius = self.myProfileView.userImage.frame.size.width * 0.5
    self.myProfileView.userImage.layer.borderWidth = 2
    self.myProfileView.userImage.layer.borderColor = UIColor().appThemeColour().cgColor
}

Constraints:

userImage.snp.makeConstraints { (make) -> Void in
            make.centerX.equalTo(self)
            make.centerY.equalTo(self).multipliedBy(0.25)
            userImage.heightAnchor.constraint(equalTo: userImage.widthAnchor).isActive = true
            userImage.widthAnchor.constraint(equalTo: self.widthAnchor, multiplier: 0.40).isActive = true
        }

Before pushing the view on the screen when it first loads:

view is still square-shaped

After I open and close the keyboard pushing the view off and back on screen:

view is now rounded

You should run the rounding code in viewDidLayoutSubviews instead, which runs after the layout has correct frames.

Also, execute layoutIfNeeded() for myProfileView before accessing its size.

override func viewDidLayoutSubviews() {
    myProfileView.layoutIfNeeded()

    myProfileView.userImage.layer.cornerRadius = myProfileView.userImage.frame.size.width * 0.5
    myProfileView.userImage.layer.borderWidth = 2
    myProfileView.userImage.layer.borderColor = UIColor().appThemeColour().cgColor
}
