User Profile

So I have this pdfView and I wanna make it so its first display is a zoom of 100% of the page, but the problem is that what I have now is zooming in to much and the UI is not pretty to be like that. It just like zooms to much and I want it to be perfectly zoomed to fit the screen size. I have tried and can't find a solution. My code is this: 		pdfView.translatesAutoresizingMaskIntoConstraints = false 		pdfView.autoScales = true 		pdfView.maxScaleFactor = 4.0 		pdfView.minScaleFactor = pdfView.scaleFactorForSizeToFit 		view.addSubview(pdfView) 		pdfView.leadingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leadingAnchor).isActive = true 		pdfView.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor).isActive = true 		pdfView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor).isActive = true 		pdfView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor).isActive = true 		 		 		guard let path = Bundle.main.url(forResource: materia , withExtension: "pdf") else { return } 		if let document = PDFDocument(url: path) { 				pdfView.document = document 		}
