Issue Description

I am trying make my frame of image auto change its size with "multipliedBy".
frameImageContainer.snp.makeConstraints({(make) in make.width.equalTo(295).multipliedBy(0.2) make.height.equalTo(355).multipliedBy(0.2) print("ratio", ratio) make.top.equalToSuperview().offset(self.view.frame.height/8) make.centerX.equalToSuperview(); })

But it not working like expected. It keep their size (295x355). Can anyone figure out what i am wrong ?
