This replaces a number of
withUnsafeblocks with use of the.spanproperty. This was introduced in Swift 6.2, so it does require bumping the toolchain version and minimum Mac deployment target.Some minor performance regressions should be anticipated, as there will now be bounds checks performed where previously these were compiled out with the use of unsafe buffers. These either should be accepted as the cost of memory safety, or investigated to see if tweaks to the code structure could help the compiler eliminate them.
