NSAttributedString.CreateWithRTF throws exception instead of returning null #23584
Description
Apple platform
macOS
Framework version
net9.0-*
Affected platform version
.NET 9
Description
NSAttributedString.CreateWithRTF throws an exception when it cannot initialize the NSAttributedString. According to the documentation it should return null in such a case.
The problem also happens for NSAttributedString.CreateWithRTFD and NSAttributedString.CreateWithDocFormat
System.Exception: Could not initialize an instance of the type 'Foundation.NSAttributedString': the native 'initWithRTF:documentAttributes:' method returned nil.
It is possible to ignore this condition by setting ObjCRuntime.Class.ThrowOnInitFailure to false.

Background: I am using this method to get RTF data from the system pasteboard (NSPasteboard.GeneralPasteboard).
Steps to Reproduce
NSAttributedString.CreateWithRTF(NSData.FromArray([0]), out _);
NSAttributedString.CreateWithRTFD(NSData.FromArray([0]), out _);
NSAttributedString.CreateWithDocFormat(NSData.FromArray([0]), out _);
Did you find any workaround?
