This is a very strange behavior when pushing vc that I have never seen since I started coding. The pushed ViewController is transparent and only navBarTitle is shown. After the push, you can't control anything unless you go back to the home screen. STEPS TO REPRODUCE Long press currency change button below.(currencyWrapper) Call selectCountry and this bug happens. SourceCode let currencyWrapper = UIView() private func configureCurrencyCard(){ //The strange behavior shows up after long pressing this currencyWrapper.backgroundColor = .white currencyWrapper.addTarget(self, action: #selector(changeCurrency)) currencyWrapper.setWidth(currencyChangeIcon.follow(by: 16, x: true)) currencyWrapper.setCenterX(w1/2) currencyWrapper.setHeight(currencyLabel.follow(by: 12, x: false)) currencyWrapper.roundToCircle(true) view.addSubview(currencyWrapper) } private func selectCountry(country: Country){ let vc = CountryViewController(country: country) vc.hidesBottomBarWhenPushed = true navigationController?.pushViewController(vc, animated: true) }
