I’ve been trying to create a new C++ project file using xcode 11 but I keep getting this error thrown at me and I’m not sure what the issue could be.

Xcode 11
OSX Catalina 10.15.3
Unreal engine 4.24.3

I’m rather new to unreal engine but could this possibly be an incompatibility with xcode 11 or possibly some missing components?

Hi there,

Also going to add to this - having the same problems creating C++ projects. Blueprint project creation works fine it seems.

My specs: macOS Catalina 10.15.4, Unreal Engine 4.25.1

Code below.

An error occurred while trying to generate project files.

Any help would be hugely appreciated - really looking forward to getting stuck in with learning Unreal Engine.

Cheers!
