Big Sur and Xojo 2019r1.1

Since I moved to using Big Sur now for macOS, I had a little trouble running apps with Xojo 2019r1, a version we still use for a couple of projects.
Lucky with a bit of searching around, I found a workaround posted by Norman Parlardy:

Big Sur and 2019r1.1
The official line is “if you want to run Big Sur you MUST use a version newer than 2019r3.2” – at least for desktop apps (web apps arent affected in the same way)

But you CAN actually get 2019r1.1 to work for desktop apps on Big Sur

Here is what I have done to be able to run Xojo 2019r1.1 on Big Sur (Intel) – and to successfully DebugRun and Build Desktop applications:

Replace these files in the Xojo 2019r1.1 application bundle with those from 2019r3.2:

Contents/Resources/SDKStubs/macosx10.14/System/Library/Frameworks/AppKit.framework/AppKit.tbd
Contents/Resources/SDKStubs/macosx10.14/System/Library/Frameworks/AppKit.framework/Versions/C/AppKit.tbd

After I copied the files, the Xojo version does build and no longer complains about UIFoundation framework missing.
Thanks Norman.
