Have you found any solution, workaround or fix for this issue? I'm having the same issue and I've not found any way to make it work, making the whole solution useless! Please Apple engineers, could you please let us know how to set the initial selected index when dealing with a TVCollectionViewFullScreenLayout? Thanks.

I ended up cleaning the entire Xcode "iOS DeviceSupport" folder as it proved to be useful in the past and I cannot reproduce the issue anymore! However, the other developer in my team has the same issue so it's not specific to my computer. I guess we will never know what was going on.

Hi eskimo, Yes, 2.0 is the expected result. Here is my detailed configuration: • MacBook Pro 2020, Intel processor • MacOS 11.4 (but reproduced yesterday with 11.3.x) • Xcode 12.5 • Simulators: iPhone 8 (14.5), iPhone 8 (12.4), iPhone 8 Plus (14.5), iPhone 12 Pro Max I always get the following result: (lldb) po (398.0 / 165.0).rounded()e-321 You don't even have to set a breakpoint to get an unexpected result (though different) as the instruction print("Rounded result: \((398.0 / 165.0).rounded())") logs Rounded result: 2.412121212121212 FYI I've filled in a bug report (FB9118612).
