Not really. I'm sure there are plenty who will just stick with Qt based options or even Electron.

I've seen a lot of stuff built in PyQt by people who aren't strictly developers and who learned Python only because it fits with some other aspect of their job. There isn't a lot to incentivise them in learning a new language.

Qt licensing can be problematic depending on your project. They also no longer publish LTS releases under an open-source license. Swift UI would presumably not be encumbered in this way.
