App updates to address 64-bit and iOS 8 requirements by Apple

Amazon among those issuing an app update that mentions 64-bit requirement, look for the same from those who regularly issue app updates like Twitter and Facebook

The relaunch issue of App Publisher will appear in a couple of weeks (we think) and one thought that crossed my mind was whether our digital publishing platform was ready for the requirement from Apple that apps be developed offer 64-bit support. We’ll check on that.

64bit-AppleEventIn the meantime, you will likely to see a fair number of new updates pass through the Apple App Store in the coming days that mention 64-bit support. The latest to appear is from Amazon who updated their main iOS app, Amazon App (snappy name, no?) last night.

In October Apple sent email notices to those holding developer license, informing them of the change in requirements:

Starting February 1, 2015, new iOS apps uploaded to the App Store must include 64-bit support and be built with the iOS 8 SDK, included in Xcode 6 or later. To enable 64-bit in your project, we recommend using the default Xcode build setting of “Standard architectures” to build a single binary with both 32-bit and 64-bit code.

Most readers probably currently own 64-bit PCs as they have been around a while. Computers with more than 4 GB of memory are running 64-bit machines (the difference between 32-bit processors and 64-bit processors is the number of calculations per second they can perform), but if you are stuck on a machine running 2 to 4 GB of RAM, and it is a few years old, it may be a 32-bit PC. But with smartphones, the move to 64-bit has been more recent.

The requirement by Apple may not have the same impact on apps as the introduction of a new version of iOS. The requirement only effects new or updated apps submitted to Apple, not existing apps.

With the introduction of a new version of iOS, however, users who upgrade their devices often see performance issues – which, sadly, often them leads to a series of updates to fix bugs, something seen all too often when iOS 7 and 8 were released.

As for the relaunch issue of App Publisher, I’ll be leaving any issues involving the app to the publisher, Paul Blake, and the team over at TypeEngine.

Apple also sent holders of paid iBooks Store accounts a notice reminding them that prices will soon change:

As a reminder, within the next 48 hours your proceeds for books will change for all territories in the European Union except in Luxembourg. Changes to publisher proceeds will depend on the changes to the value-added tax (VAT) rate in each territory. You can view updated VAT rates in the FAQ.
