Apple reminds developers once again of upcoming 64-bit requirement for iOS apps

Screen Shot 2015-01-19 at 8.42.43 PM

Apple has issued what will likely be the final reminder for developers building iOS software about the upcoming changes to requirements for new app submissions. Starting on February 1st, all new apps submitted to the App Store must include 64-bit support and be built using the iOS 8 SDK.

Existing apps already in the store won’t be removed if they don’t meet the standard, but starting in June, any further updates submitted for those apps will need to comply.

Apple had previously announced that developers of new apps must support 64-bit architectures (to take full advantage of the A7 and A8 technology) by February 1st, 2015. Today, Apple has reminded developers of this deadline as well as clarifying the situation for existing apps.

Google Chrome for Mac goes 64-bit in latest update, gains new APIs and other enhancements

Screen Shot 2014-11-18 at 6.20.00 PM

As promised in September, Google has launched the 64-bit of the Chrome browser for Mac to the public after a few months in beta. According to Google’s original announcement, the update drops support for 32-bit extensions, requiring all developers to update with 64-bit support.

The update also fixes over 40 security flaws and adds many new APIs for extension developers. Chrome uses a silent update mechanism that will automatically download and install the latest update, but if you find that you’re still on version 38 in the “About Chrome” window, you can manually download and install the update from Google.

Apple to require iOS apps and updates to use iOS 8 SDK and include 64-bit support from February 2015

Apple has today notified developers about some upcoming rules regarding App Store submission, via its developer news portal. From 1st February 2015, newly-submitted apps and updates must be built against Apple’s iOS 8 SDK. This is not particularly surprising: Apple required similar adoption of the iOS 7 SDK last year.

In addition however, Apple will also require that all apps and updates include 64-bit support from that date too. Currently, developers can choose whether to submit only 32-bit apps or universal binaries. This will no longer be an option from February. Moving all apps to 64-bit will bring big performance and memory gains for newer devices (which include A7 or A8 SoC’s) as running the 32-bit apps necessitates loading a lot of additional resources into system memory.

Public version of Google Chrome for Mac will go exclusively 64-bit in November

chrome-mac-64-bit-dev-channel

Last month Google released a 64-bit version of the Chrome browser for OS X on its developer channel. However, this version of the app has not yet been made available to the general public. Google announced today in a blog post (via iMore) that the browser would be updated in version 39 not only to add 64-bit support, but to remove 32-bit support.

That means that any 32-bit plugins built on the Netscape Plugin API will no longer function until they are updated for 64-bit systems. This update will be released in November, though an exact release date hasn’t been given yet. Because Chrome uses a silent auto-update mechanism, users won’t have to do anything special to get the update.

Qualcomm employee said Apple’s 64-bit A7 chip was Spinal Tap moment

If Qualcomm seemed rather taken by surprise by Apple’s use of a 64-bit chip in a smartphone, first dismissing it as a gimmick and then hastily backtracking and announcing it would be making 64-bit smartphone chips itself, that’s because it was, says Dan Lyons in a nicely-written piece on HubSpot. The piece includes what has to be a strong contender for tech quote of the year:

The 64-bit Apple chip hit us in the gut,” says the Qualcomm employee. “Not just us, but everyone, really. We were slack-jawed, and stunned, and unprepared. It’s not that big a performance difference right now, since most current software won’t benefit. But in Spinal Tap terms it’s like, 32 more, and now everyone wants it.”

The reference is to a scene in the 1984 mockumentary This is Spinal Tap where the band proudly shows an amp that goes all the way up to 11, explaining that “it’s one louder.” What Qualcomm missed was that while 64-bit smartphone chips may be of limited immediate value, the A7 made for a compelling marketing sell, leaving other companies scrabbling to catch up.

Qualcomm has just created a 64-bit version of its Snapdragon SOC and expects to see it appearing in Android phones sometime in the second half of next year.

Ahead of the iPhone 5s’s launch later this week, Apple has put up a notice for developers to start submitting 64-bit compatible App Store apps. One of the iPhone 5s’s marquee features is a new 64-bit A7 processor that improves gaming and speed performance across the system and apps. Apple’s notice to developers:

Apple said to have tested 64-bit ‘A7’ chips for iPhone 5S, 31% speed increases reported

As Apple’s iPhone 5S event approaches, some new details about the new device’s internals are emerging. Clayton Morris has claimed on Twitter that the iPhone 5S’s A7 processor is “running at about 31% faster” than the iPhone 5’s A6 chip. The iPhone 5’s A6 chip is dual-core, and it seems like the iPhone 5S will also remain dual-core.

However, there could be a major differentiator: 64-bit. We’ve independently heard claims that some of the iPhone 5S internal prototypes include 64-bit processors.

It’s unclear if 64-bit will make the cut, but it’s been in testing. We’re told that the 64-bit processing will assist the A7 chip in making animations, transparencies, and other iOS 7 graphical effects appear much more smoothly than on existing iOS Devices…
