Night Shift only for iPhones?

Yeah only 64 bits. I don't see how a color temperature feature need 64 bits, Apple is trying to push people to upgrade to newest devices even if their old one could easily have this feature.
They probably implemented the feature into the 64-bit only Metal rendering engine and didn't bother to mess with the old Open GL engine. Same for Safari and content blockers.
Wait! Why isn't it available on the 2007 iPhone? Planned obsolescence, blast it!
I doubt that this has anything to do with Metal. The 64-bit processors are just more efficient and of course more powerful at iterating through lengthy block lists.
I suspect that Night Shift builds upon ProActive instead and that Apple didn't bother implementing a workaround for those devices that don't have the backend that monitors time and place.
It's 64bit because moving forward iOS will eventually be a 64bit only OS. No sense developing for 32bit devices if they don't even offer 32bit devices for sale anymore. Every iDevices has been 64bit for the last 2-3 generations now. If iOS 10 doesn't become a 64bit only OS, I would pretty much fully expect iOS 11 to be.
No it doesn't have to do with proactive because the iPhone 5/5C don't have night shift. They have proactive though.
Then I suppose it is just a 64-bit dependency they rely on. Apple has previously had the tendency to drop support for technologies that are outgoing. But I don’t think it is dependent upon Metal.
I wonder if anyone took a deep look at the low level code yet to see if these new features is coded in Swift now, Swift is also 64-bit only at the moment. Apple is starting to build more and more in Swift and thus the 64-bit requirement.
Federighi mentioned this issue in his interview with Guber that Swift only has a 64-bit runtime and certain teams are starting to get into Swift. The dock on El Capitan is fully coded in Swift already.

Like I mentioned a few posts up. Apple is most likely only giving a lot of the latest features to 64bit devices because iOS is mostly likely moving towards 64bit only soon (maybe iOS 10, of not I would for sure iOS 11.) They don't offer any 32bit for sale in their store anymore. So there is almost no reason to keep supporting 32bit moving forward. Sure there are a number of people with 32bit devices still but in order to keep moving, support has to eventually stop.
