I have this code which uses Unmanaged and the API seems to vary depending on if
I am using a 3.0 Preview or a development snapshot. I see it now when trying
the June 13th/27th preview vs June 20th snapshot.
class MyClass {}
let holderObject = MyClass()
#if FLIP // works with PREVIEW
let leakyObject = UnsafeMutablePointer<Void>(OpaquePointer(bitPattern:
Unmanaged.passRetained(holderObject)))
#else // works with SNAPSHOT
let leakyObject = Unmanaged.passRetained(holderObject).toOpaque()
#endif
#if FLIP // works with PREVIEW
let unleakyObject =
Unmanaged<MyClass>.fromOpaque(OpaquePointer(leakyObject)).takeRetainedValue()
#else // works with SNAPSHOT
let unleakyObject =
Unmanaged<MyClass>.fromOpaque(leakyObject).takeRetainedValue()
#endif
I see the same difference between the previous snapshots and previews all the
way back to the “false” preview of yore.
Am I misunderstanding something about the API or is this a bug?
Thanks,
-Kyle
