SwiftGogot 0.46

This version of SwiftGodot includes the following changes:

Features

• Support for Godot 4.3 APIs, apologies for the delay.

Performance

• Allocation-less marshaling for built-in and class types methods. The runtime no longer needs to allocate temporary variables to call into Godot, we now pass data directly from the stack (Elijah Semyonov)

• More progress to perform Vector3 operations in Swift-land, without having to call into Godot to do the (Elijah Semyonov)

• Arguments are now borrowed, without being copied (Elijah Semyonov)

Quality of Life Improvements

• Warn users if they declare types that conflict with Godot types (Rob Mayoff)

• Large class of memory leaks with variants have been fixed in a multi-week effort by Elijah Semyonov that tracked every single dangling reference to their root cause. This is truly a gift of the gods for all SwiftGodot users.

[#545], [#541], [#542], [#548], [#550], [#552], [#551]

And also a great test suite to ensure we do not regress.

• New marshalling infrastructure that works on Windows, and removes the previous optimization that was failing to compile on Windows.

Fundamentals

• Fix deprecated code usage (Luke Puchner-Hardman, Elijah Semyonov)

• Fix a scenario where we did not lookup the most-derived type (Justin Anderson)

• Fix crashes on some indexer operation (Elijah Semyonov)

Maintenance

• Avoid name clashes with swift language keywords (Jakob Winkler)

• Remove hard-coded values on my development system so everyone can enjoy it (Elijah Semyonov)
