Corner radius for UIButton not working after upgrading to Xcode 8

Question

I am setting the corner radius of UIButton as follows:

self.btnFBLogin.layer.cornerRadius = self.btnFBLogin.frame.size.height/2;
self.btnFBLogin.layer.masksToBounds = YES;

However, after upgrading to Xcode 8 it is not working. Button is not displayed in screen. However, if I do not set the corner radius it displays as a square box. Has anybody faced similar issue?

In XCode 8, due to their new zooming system, bounds and frame are not correct before ViewDidLayoutSubviews (they may exist but with dummy values like 1000 x 1000) - http://stackoverflow.com/a/39495236/3150830 — Ashildr, Sep 19 '16 at 10:29

In all probability you are running that code too soon (e.g. viewDidLoad). Do it in, say, viewDidLayoutSubviews.

Yes. That's exactly I did. – Sujit Dalai Sep 18 '16 at 22:12

Reviving this post as I had the same issue. I solved this issue by calling `layoutIfNeeded:` before setting the corner radius. What's the disadvantage of this approach? – Andrea Apr 08 '22 at 18:57
