I have tried a way but after generating pptx it is not opening may be some configuration xml are missing. This code converted pdf to pptx but that file is not open say some error "Sorry are cant open this file." I want to converet using core Swift.
Each PDF page becomes
ppt/media/imageN.jpg.Each slide
ppt/slides/slideN.xmlcontains one<a:blip r:embed="rId1"/>— the slide-level relationship fileppt/slides/_rels/slideN.xml.relsmapsrId1→../media/imageN.jpg.ppt/presentation.xmlreferences all slides viarId1,rId2, ...[Content_Types].xmllists slide and media parts.The folder is zipped with
ZIPFoundationto produce a valid.pptx.
