In past years I've had a spare Mac I could use but that Mac can't run Monterey so I'd like to install Monterey on a separate APFS volume on my M1 MacBook Pro. I've read the instructions here: https://support.apple.com/en-us/HT208891 but I want to be certain I don't causes issues with the Big Sur installation. Obviously after backing up, I use DiskUtility to create a new APFS Volume. If I download the macOSBetaDeveloperUtility.dmg and install it, then I think it will give me the option to update the OS (as that's what I did in the past, but it's not what I want to do this year). From screenshots here: https://support.apple.com/en-us/HT208891 I think it will allow me to choose where to install and I can choose the new APFS volume I made for the beta. Is that correct? And then after the installation, will the Big Sur volume work as before or will software update in it want to update to the Monterey beta instead of letting me do any Big Sur updates that come out this summer? And then at some point after the official Monterey release, I assume I can just delete the APFS volume I created for Monterey to test my apps and then update the Big Sur volume to the official version of Monterey? Are there any mistakes in my steps/plans? Thanks, Dave

At about 33:30 of the Demystify SwiftUI video, it indicates the problem is the id isn't stable. Since it is a computed property, the UUID() function is called each time the property is accessed and a different value is returned. The simple fix is to instead use let id = UUID() isn't it or am I still misunderstanding the problem? Thanks, Dave
