Thanks for your tutorial!
But is it possible to change blur radius programmatically?

@edekhayser Can you please help with this when you get a chance? Thank you - much appreciated! :]

@nastenkomisha Unfortunately, as of iOS 11 this is not available to developers. I would check the documentation again once the WWDC betas come out, as this is a plausible change they could make.

A workaround would be to change the alpha of the visual effect view, but this is not officially supported and may lead to bugs that I don’t know about.

This tutorial is more than six months old so questions are no longer supported at the moment for it. Thank you!
