    Apple is now permitting developers to submit 64-bit apps to take advantage of the A7 processor in the iPhone 5s, according to a note posted to the company's developer site today.

    Developers with apps that function on both iOS 6 and iOS 7 will be limited to 32-bit development for the time being, but Apple has plans to support a single app binary for both 32-bit and 64-bit apps in the next month.
    First unveiled last Tuesday, the iPhone 5s incorporates the first 64-bit processor found in a mobile device. According to Apple, the processor offers double the power and graphics performance of the iPhone 5 and is 40 times faster than the processor of the original iPhone. 

    In addition to an A7 processor, the iPhone 5s also includes a Touch ID fingerprint sensor, an M7 motion-sensing chip, a number of camera improvements, and better battery life.

    Apple is not accepting pre-orders for the iPhone 5s, which will be available for purchase from Apple's online store beginning at 12:01 AM Pacific Time on Friday, September 20.

    Update: Apple has removed the note for unknown reasons.

    I'd imagine the developers would need a little more time to recode for 64 bit? How would they even test this?!?

    You would have to be exceedingly brave to submit a binary built for hardware you don't actually have yet, and have not tested on.

    I don't fully understand the benefits of 64-bit on the iPhone at this point, but I'm all for improvements and building for the future!

    That'll put a damper on launch-day 64-bit apps, but it sounds like there won't be many 5s units out in the wild for a bit anyway.

    There's really no re-coding. Basicaly, it's compiling the code through a 64-bit compiler in addition to the 32-bit compiler and testing the code. In rare cases, there will need to be a few fixes, but in general, the same code can be compiled for both 32-bit and 64-bit.

    In the keynote the Infinity Blade devloper recompiled his game in 64-bit in less than 2 hours using the new features in xCode.

    Granted, I'm sure people would need more time for testing and ensuring everything compiled smoothly.

    More than a bit better.

    Having learned to hand assemble for an 8-bit it amazes me how far we have come.

    Unless you're using an older Mac which is running an old version of OS X, your iTunes should be "Intel 64 bit", you can check in Activity Monitor.

    My Mac mini has a Core 2 Duo, my OS X version is 10.8.4 and my iTunes is 64 bit.

    Lack of single binary for both 32-bit and 64-bit is code for "you won't exactly see many 64-bit apps for at least a month." We're talking Infinity Blade III and ...?

    And yet still no word of 64 bit Android. We're so far ahead of them it's hysterical. :D If you want 64 bit desktop performance on your mobile there is only one player in town.

    Ah, those were the days. Programming for a 6502, those machines only ran at 1MHz(?) but they flew since there was no overhead. (The lower resolutions really reduced the amount of bits to move around too!).

    Depends...
    The changes can be quite significant to the point where certain parts of the code simply won't compile (or compile then crash your machine because they make wrong assumptions.)

    In my view the apps that will benefit the most from being 64-bit, generally won't compile if they use 32-bit code.

    iMovie or iPhoto and a few other Apple apps are probably ready for the hybrid versions in-house (they've got the new compiler!).

    Any new apps that don't need or want to support the older OSes.

    I'm reminded of all the "WHY ISN'T ITUNES 64-BIT YET???" threads here, yet no one could actually explain the benefits of it being 64-bit for the average user.

    The best part is yet to come...Once they do have (multiple implementations of) 64bit chips to use, mass confusion will ensue with programs running only on certain processors, etc.

    The reality is Apple is about to prove beyond a shadow of a doubt why Android is fragmented and more effort for devs to program for. Imagine making 6 or 8 binaries for your program vs. 2 for iOS7.0 and possibly one for iOS7.1.
