Is Apple stopping any further support to 32-bit devices? It came to light last week when I tried to install Apple Clips App to my iPad which is a 32-bit device. A software upgrade was due and so I ended up upgrading it to iOS 10.3. I tried installing the App and again it was not compatible. I waited for the next upgrade and this week it got upgraded to 10.3.2. But still the app was incompatible.
I realised Apple will abandon its 32-bit devices in the upcoming iOS 11 release. In fact, it has released an advisory that that using a 32-bit app will slow down 64-bit devices. It looks, Apple will slowly remove Apps that do not support 64 bit devices. If you encounter such a message when installing any app, all you have to do is to ignore and continue. Developers were informed that any Apps and future updates submitted to App Store since July 2016 must include 64-bit support.
It is simple why Apple prefers 64 bit supported apps. When you use a 32 bit app, the machine launches its original 64 bit versions of kernel libraries and drivers while it needs to use the 32 bit versions too which strains the RAM and battery resulting in loss of power and speed.
For the record following iOS devices are 64-bit:
- iPhone 5s/SE/6/6s/7
- iPad Air and iPad Air 2
- iPad mini 2, iPad mini 3 and iPad mini 4
- 12.9-inch iPad Pro and 9.7-inch iPad Pro
- 2017 iPad
