@eskimo - will this also get fixed for BigSur? Not everyone has and will have Monterey.

Reportet a bug to Apple. The provided a "courtesy feedback" that Xcode 10.x is not supported on Big Sur. To bad they don't tell people before they upgrade to Big Sur...

I sent this as a bug report to Apple. I couldn't find any official announcement that would end Xcode 10.x support for Big Sur.

Get another Mac with an older macOS which can run Xcode 10.2 (or 1 or 3). Yes, I have that and it works. But my question was about how to get Xcode 10.x working on Big Sur.

After upgrading to macOS Big Sur I installed Xcode 10.1, 10.2.1 and 10.3 on two separate Macs and I can say Xcode 10.x doesn't run on Big Sure. It's crashing each and every time I try to launch it. Any idea what can be done?

Can you elaborate on this? Can you point me to resources that explain how this should be done these days?

Adding <key>NSLocalNetworkUsageDescription</key> <string>Looking for local tcp Bonjour service</string> <key>NSBonjourServices</key> <array> <string>remote-for-zoom.tcp</string> </array> to my Info.plist solved the problem but now I get this pop up that says your app would like to find and connect to devices on your local network. Looking for local tcp Bonjour service. Can this be avoided? I have so many other apps that user Bonjour and they don’t bringt this pop up… Thank you Thomas
