I'm trying to port an application from PyQt5 to PySide6 because it's the official bindings (for now I guess). I have a .ui file designed in Qt Designer. It loads fine using PyQt5 uic, but PySide6 gives me the following error:

Designer: An error has occurred while reading the UI file at line 1, column 38: Unsupported XML version.

The first line of that file says:

<?xml version="2.0" encoding="UTF-8"?>

I've tried loading the file dynamically and I've tried to compile the .ui file using pyside6-uic. I get the same error each time.

Why can't PySide6 read my ui file?

There's no such xml version as 2.0 - the only specified versions are 1.0 and 1.1. Qt will currently refuse to load ui files that aren't xml version 1.0, so I don't know how you ended up with anything different. Anyway, just manually change the version to 1.0, and everything should work as expected.

PS: as a nice irony, the so-called "unofficial" PyQt tools will handle any xml version, valid or otherwise (-;
