I'm very new to mobile app development, and though I've settled on using Svelte-Native at this point, I was considering various frameworks a couple of weeks ago (React Native and Kivy). Svelte-Native's, Your First App, was the first tutorial I tried, and at that time everything worked just fine. I then looked at React Native and finally considered Kivy. I never ended up getting Kivy to work, but that in it of itself is fine – I'm not going to use it for the time being. However, while I was trying to get Kivy to work, I had to tinker around a lot in Xcode's settings. My suspicion is that it threw some sort of configuration on such a low level, that it's affecting NS Preview and NS Playground.
When I run, ns preview, the QR code displays just fine, but then when I scan my it with my iPhone 12, and I get an error log both in my terminal and on my phone.
