pdfData method of your renderer: let data = renderer.pdfData let pageRect = CGRect(x: 0, y: 0, width: 595, height: 842) let renderer = UIGraphicsPDFRenderer(bounds: pageRect, format: format) Page dimensions would be: // US Letter Width: 8.5 inches * 72 DPI = 612 points Height: 11 inches * 72 DPI = 792 points // A4 would be 595 x 842 pointsĪfter doing this math, we need to instantiate UIGraphicsPDFRenderer object, which is responsible of document rendering. PDF documents use a default resolution of 72 DPI. And we add a progress indicator and opacity animation for smooth transitions. We also have closure to know refresh the PDF in our ContentView when done editing.
So I’m going to add this: var startEditMode PassthroughSubjectSecond, we need to calculate PDF page dimensions. So it just lives in waiting within our SwiftUI views.
