Thank you for looking into this. As I was following the steps to install the logging profile, then running Xcode to see the SwiftUI preview with an iOS18, it worked as expected. I have not been able to reproduce the issue since.

Well.. you saved me from throwing my computer out the window. Thank you !

@Megamil Sadly this issue was not fixed! I just upgraded Xcode, tested my app and it continues to load the wrong style ( regular, medium, bold etc ). The only walk around I have found is that if you go and switch the affected label to a different 'Style' and then back to the one you want, it will fix it. However, I am not 100% sure what happens when you submit it to the App Store and is installed in actual devices.

The only thing you can do now is add the fonts programmatically to your labels and buttons.

It's worth noting that the fonts that were supposed to be "normal" are now bold, and the bold change to thin.

No, it’s not enabled. The app behaves normal when downloaded from the App Store. But while running it on the simulator or on my device on iOS17 Beta from Xcode the font weight changes.

I am sure that you must display it where you show the weather. I'm waiting for them to review my app hoping it gets approved. I do show weather and the attribution where the weather appears. So, I am thinking it would be ok.
