Fragmentation Comes To iOS

Posted by timothy on from the all-nimbly-pimbly dept.

dell623 writes "While the fragmentation issues in iOS are nowhere near as bad as Android, it can no longer be considered non existent. I have prepared a chart showing which features will be available on which device. While some restrictions are the result of hardware limitations, it is clear that Apple has deliberately chosen to limit some previous generation devices, and figuring this out isn't always straightforward if you're not buying the latest iPad or iPhone."

      Is slashdot just linking to people's random ass blogs now? This has got to be the most pointless and uninformed article I've ever seen here. Or it's a troll.

      I have an ad-blocker, but I assume the page has ads on it and the submitter is just looking for some hits. Nobody should RTFA, just read this post.

      He has four products on there that are not currently being sold. One is entirely made up, with made up specs, in a product category that doesn't exist.

      Of the remaining six, there's not much fragmentation at all. There are four screen resolutions, which is the only thing developers (for which the term fragmentation typically applies) need to worry about. This includes the 3.5" iPhone/iPod retina display resolution, the new 4" iPhone/iPod retina display resolution, the iPad retina display resolution, and the older non-retina iPad display resolution, which is automatically converted. The submitter made several factual errors with the resolutions, but that's the gist of it. Clearly going forward, there will be just two resolutions that developers need to worry about. One for the iPhone/iPod, and one for the iPad, as the older resolutions are being phased out and don't exist in any new products. This means the platform is no more fragmented than it was when the iPad was first introduced.

      There are no dramatic API differences between the various iOS platforms, just the usual and obvious differences in available hardware. iPods and iPads don't have cell network assisted GPS if they don't have chips in them to access cell networks. iPods and iPads don't have Facetime over cell networks when they don't have chips in them to access cell networks. Advanced features of the camera system or microphones are not possible on devices lacking the necessary computing power to handle them.

      All in all, nothing in this random submitter's blog post addresses true fragmentation, the sort you see in the Android platform due to API differences and hundreds of different screen resolutions.

  2. It's not the same issue. by Anonymous Coward · · Score: 5, Informative

    Fragmentation is a developer problem that affects how easy it is to roll out software for the platform.

    Apple keeps the core APIs consistent across devices. Everything you have listed is unrelated to the developer's ability to build their own apps.

    Those are end-user features.

  3. Not great by Bogtha · · Score: 5, Informative

    Most of these are things that iOS developers don't care about. For instance, Facetime over cellular: developers don't care about that, it's an Apple app, not an API, and evenif it was an API, you'd have to code for when it's unavailable anyway.

    There are variations between the different models that developers have to be aware of, but they aren't covered in this chart. For instance, background modes are only available for ARMv7 devices. By and large, Apple have done a good job of shielding developers from these differences. I'm an iOS developer, and I very rarely have to even think about different device support. The two main ones are display size and display density - and Apple have only just announced the third display size ever, and they've only used two display densities ever. I can't really think of any platform outside of games consoles that are so homogenous.

  4. Re:PCs are fragmented by sunderland56 · · Score: 5, Funny

    Uh, yeah. PCs are pretty much the poster boy for a fragmented platform,

    Yeah, but every PC comes with a defragment utility.
