Apple tells developers that existing app updates will need to be 64-bit by June 1st

Apple tells developers that existing app updates will need to be 64-bit by June 1st
Today, Apple posted a notice to developers to remind them that starting on February 1st, new apps submitted to the App Store must include 64-bit support and be built using the iOS 8 SDK. Starting on June 1st, the same requirements are necessary for updates submitted for existing apps. Apple has told developers that by using the default X code build setting "Standard architectures," they can build a single binary with both 32-bit and 64-bit code.

Forcing developers to include 64-bit support should remove some of the pressure from iOS, since apps now have to load 32-bit runtimes to be backward-compatible. The new rules though, won't affect any iPhone model older than the Apple iPhone 5s. It was the latter that first brought 64-bit processing to a smartphone.

Apple gave developers a heads up about the change in October, offering a 6-month warning on the 64-bit requirements for new apps. Today's warning gives developers working on updates to their apps, a similar warning.

What a joke. Microsoft invented 64 bit computing and they were the first to bring it to the Nokia Lumia 1020, and 1520. Sad to see that Apple is only beginning to catch up to Microsoft.

Dude,you know your phone and OS sux a lot ?

Why do you say that? I'm sure we have a lot in common. We both like Snapdragon chips, and my 1520 runs faster than any phone thanks to the SD 810 chip.

The Lumia 1520 has the SD 800, not the 810...

they are good phones but without enough ram memory 64bit mean zero effort same call to ios and adroids I just wonder what all that hype about 64bit without hardware support?? another gimmick?? then why over pay for that

Wow, that's amazing. All that information in one post, and not a single thing correct.

He's what we can call a "die hard fan boy". Hes so smitten with microsoft and Lumia devices that he's willing to lie for them.

Dude Microsoft mobile OS is horrible!! Stop copy and pasting the same post over and over. If I worked for Microsoft I would have you arrested for trying to defend my company lol get a life

Dude you are giving anyone who likes Microsoft OS a bad rep due to how misinformed you are. I like wp better than all but android but you are of below average intelligence. Are you sure your name isn't Wendy?

@post 19, What about SD 810 on lumia 1520.. you think that's not misinformed??

Google should do this too Especially with some Nexus 9 users complaining about some 32-bit apps being slower

Apple has had a 64 bit devices since the iPhone 5S release, now with the releases of both the iPhone 6 and iPhone 6 Plus. Google has yet to release a 64 bit device, although the new 64 bit devices are scheduled for release next year. It is hard to ask the developers to build 64 bit apps when no 64 bit devices have been released.

Well why would they begin using 64 bit before now? forward steps are always good but unless you actually make use of the advantages 64 bit gives, then 32 bit is more then fine for all the apps that are around currently, with maybe only a few exceptions. Slapping on 64 bit doesn't make anything go faster unless it actually makes use of what the 64 bit processor provides. That said for android it seems like a logical step forward many phones are beginning to have 3gb of ram and devs would probably want to go higher still, and 32 bit limitations would then prevent them. I don't even think there's an ios device out there with 2gb of ram? although I might be mistaken? and last I checked the apps on ios aren't so radically different from those on google store that they would benefit greatly from it yet? But yes everyone moving to 64 bit, on all os' not just mobile will probably make workflow and programming easier.

64bit is not only for if you have 4+ gigs of ram.

I am aware, maybe I didn't point it out correctly, I did not mean to indicate that ram was the only advantage, my main point is though that in the vast majority of common stuff that smart phones do there is little to no advantage to 64 bit processing as it is currently. Yes, 64 bit has advantages, but it isn't advantages that we have needed at least until phones began getting more ram, and in that case the ram is the most significant advantage. Especially since the vast majority of apps still run 32 bit, is it good that they are going towards 64 bit, yes, will it make the vast majority of things done on smart devices faster? Nope, very unlikely.

Google has yet to release a 64 bit device? What do you think the Nexus 9 is? HTC Desire comes in a few 64 bit models too. Galaxy Note 4 comes in a 64 bit version as well.

I think you missed the point man. I agree there are a few 64 bit android products but not near as many as on Apple so I agree apple should be advised them to start making them 64 bit compliant. Also don't go all defensive on me and accuse me of being an apple fanboy.. I currently use a note 4.

Well there isn't really a 'need' for 64 bit so there hasn't been a push for it, up until the ram limit that is being hit by android devices now/shortly. 64 bit isn't going to make the vast majority of what smart devices work any faster or give significant improvements.

I agree but on apple it is a bit different because they have had 64 bit specifically for over a year so it makes since for Apple to want that from developers. On Android there hasn't been many and what is there hasn't been huge on sales (yet). That, I'm sure will change as more are distributed. I'm sure that push by Google to tell developers to code for it will happen when the sd810 is released

When they have 64 bit out, it only makes sense to begin to push it, but in terms of advantages, I don't think 64 bit really has any currently over the 32 bit versions of IOS and its apps. So yeah, I totally agree, though still think 64 bit from apple was more a PR stunt then anything.

I absolutely agree it seems more about chest thumping on apples part but it seems that it has successfully done one thing.. It has other platforms pushing forward with 64 bit too.. Who knows what developers and Google will do with it, might surprise us

24. RebelwithoutaClue unregistered

Ofcourse it makes more sense for Apple to make 64 bit mandatory, I think it's a smart move. Google should make more demands on devs as well (not only 32/64 bit, but also design wise). I wasn't defensive,I was just correcting a statement he made. And where was I accusing you of being an Apple boy?

With Android having a much much larger variety of hardware it runs on, 32 bit is likely going to stick around for a long time yet and that's not really a problem if you ask me, since I really doubt any mobile app maybe with the exception of cryptographic ones, will need 64 bit for a long time yet, as for design, needs to be 'some' guidelines at the very least there are some insanely weird apps about design wise, don't get me wrong, devs should be allowed to use the design they want, but some of the apps about I think only the dev can make heads or tails in terms of design.

I am ignorant on this 64bit mobile technology so I have a question: Since it will be a 64bit hardware and OS, isn't it safe to say that 32bit mobile apps are already compatible and will run smoothly just like in a PC with 64bit Windows that can run old 32bit programs?

Yes, 64 bit processors are backwards compatible.
