Hi,

Which version of Qt ?
Which version of iOS ?
What's the path ?
Does your application have proper permission to access storage ?

@jsulm Hello, I found that I need to use oc and qt for mixed compilation, but I can't add the Foundation framework in cmake. How should I add it?

I checked the information and he said that iOS can only read and write at the location "QStandardPaths::standardLocations(QStandardPaths::DocumentsLocation).last()"
