macOS Catalina - Rez error (bad CPU type in executable)

I'm trying to build an AU for my piano plugin.
The build goes fine, but right at the end I get a Rez error:
rez: error: can't exec '/Users/admin/Downloads/Xcode.app/Contents/Developer/usr/bin/Rez (errno="Bad CPU type in executable
I know that catalina refuses to run 32 bit apps and it seems like that's what its doing here - so how are people building using catalina, is there a 64 bit version of Rez somewhere? My JUCE project is set to only build the 64-bit AUi.
I know @dustbro is using catalina, so any input you might have would be greatly appreciated
I'm using XCode 10.3, as 11 was giving errors.
n.b. I don't have a mac, but i was able to rent a cloud mac server. Unfortunately I chose Catalina without realising all the trouble it would cause me - downgrading the OS would mean i have to buy a new server, which I don't want to do I can also build, sign and notarize VSTs just fine.

I managed to fix this - the easy way would've been to download the newest version of XCode and use the command line tools from that, but I didn't have enough space on my cloud server. So I downloaded just the command line tools for XCode 11 and replaced the command line tools inside of the XCode 10 .app with the new ones. Hopefully this helps someone else
Can confirm this works with Catalina 10.5.7 and using the command line tools from Xcode 12, looks like just the Rez and ResManager. I copied the xcode 12 versions from Xcode12.app/Contents/Developer/usr/bin/Rez to Xcode10

@tompower Hey man. So in this case should I download Xcode 12, get the Rez file, and finally download xcode 10?
