On an iMac Retina 5K, 27-inch, the render time is ridiculously slow and unresponsive.
It's not the graph, even though data arrives 3 times per second with 920 data points. I've tested this in standalone code - and its fast.
The text and buttons need to be updated at a similar speed.
Although this may appear to be working, it's far from being responsive. In fact, it's only possible to quit the program with a Command-Q, and displaying a basic About box takes forever.
I think my Views are well structured, with most modifiers factored out, so should I conclude that SwiftUI is not suitable for anything beyond a simple REST app running on IOS? I hope not. If Apple were writing something similar, how would they go about it?
I've spent over a year developing this app - wishing and expecting for Apple to come up with something better that doesn't run the entire UI on one single thread, and perhaps able to execute sub-views concurrently as one would expect.
I don't wish to sound critical. I just want to know how to get this UI rendering faster, so I'm crying out for help and advise.
