Hey everyone,
One of the things that came up in a code review today was the type of KVO's
context param. If you look at the function signature it gets imported as
UnsafeMutableRawPointer?. Is there ever a need to mutate this parameter, and if
not can we change it to be UnsafeRawPointer? instead?
We commonly define a constant (e.g. kvoContext = 0) to pass in, but in Swift we
have to make it mutable (which we'd rather not do). Is there another
workaround? How is everyone else handling this? (We avoid KVO whenever
possible, but some APIs require it.)
Thanks,
-Tyler
