Sample Swift code for using PDFTron SDK to programmatically convert generic PDF documents into ISO-compliant, VeraPDF-valid PDF/A files, or to validate PDF/A compliance. Supports all three PDF/A parts (PDF/A-1, PDF/A-2, PDF/A-3), and covers all conformance levels (A, B, U). Learn more about our Swift PDF Library and PDF/A Library. A command-line tool for batch conversion and validation is also available.
