There’s a great debate about what versions of Xojo work on Big Sur.

IF you want to build DESKTOP apps you must use 2019r3.2 or later. Even an empty project fails to build properly.

They rely on a framework that Apple has removed and so the linking of them will fail.
Linking Executable ld: file not found: /System/Library/PrivateFrameworks/UIFoundation.framework/Versions/A/UIFoundation… Read the rest

Alternatively – why Xojo should put everything in a Xojo namespace and NOT make anything global

I have a few projects that are the results of many many years of coding.

Updating them to the very latest version of Xojo ends up with lots of conflicts since Xojo added a String module with their own global extends for EndsWith and many others that have existed in other peoples code for years.… Read the rest

// suppose class1.kConstant is a string constant
dim c as new Class1
dim v as string = c.kConstant

Way back when, when Apple still permitted 32 bit compiles, the landscape for what you had to do to build an app that would work on macOS was a lot simpler.

Now, not only do you have to build the right kind of executable you need to also do code signing, even if only ad-hoc signing, to run even a debug app on the very latest versions of macOS.… Read the rest

In Xojo an array is limited to being no more than 2 billion entries (2,147,483,646 )

But arrays are documented as using integers which, in a 64 bit world, should be a LOT more entries than this.

When this post was written the documentation isnt clear about what the maximum size of an array IS.… Read the rest
