The Bevy iOS crates have been updated to remove the need for Swift packages, simplifying the installation process to a single "cargo add" command. Previously, each crate required a corresponding Swift package to be added to the Xcode project, but this is no longer necessary due to the use of the objc2 library, which generates framework bindings for Apple's Objective-C frameworks. This change eliminates the need for hand-written bridges and allows for a more streamlined development process, with the bridge now being a dependency rather than something that needs to be shipped separately.
