Comment on Apple releases iOS 15.8.7 to fix Coruna exploit for iPhone 6S from 2015

This is nice in that Apple acknowledges that iPhone 6s and iPhone 7 devices still exist and are used. I wish third party developers would read that memo and get with the program. The App Store is becoming a ghost town of "This app stopped supporting your icky old device" warning messages due to app developers abandoning these phones.

Apps don’t support devices, by and large. They support SDK versions. Targeting a 4 year old SDK means not using a fair chunk of new OS features, which translates to at least some lost sales and developer happiness.

I’m sympathetic with your point, truly, but I also get why devs would aim at newer OSes.

I think you might be confusing two things. iOS developers build against a particular SDK, but they specify a deployment target which is an OS version. You can build against the latest or near-latest SDK (in fact Apple requires you to), while still targeting arbitrarily old OS versions. The developer changes these independently.

Developers can easily use APIs introduced after their deployment target OS. So if you want to target iOS 15, but use APIs introduced in iOS 17, you can easily do this with a runtime check.

Many iOS developers choose to increase their deployment target, which accomplishes nothing for the user besides locking out older devices, while making the developer's life more comfortable (he can abandon those runtime checks and code paths that only run on older devices).

But if you are disciplined and care about your users on old devices, you can very easily target those old devices while still using the latest and greatest OS features on devices that have them.

I think I saw a YouTube video where some developer said that Apple requires you to use latest version of Xcode, that version has a minimum SDK (I think iOS 15) and he was complaining he couldn't update his iOS 12 targetting app anymore.

Was it this video? https://www.youtube.com/watch?v=WXqVV8_GORE

He finds a solution involving copying files across from an older version of xcode

I believe Apple makes it difficult, but not impossible. At the end of the day, these things are specified in text files that can be edited, regardless of what options the GUI gives you. Definitely shame on Apple for trying to nudge developers to give up on older phones, but it aligns with their desire to keep their customers buying new phones.

And the ‘features’ also involve lot of performance updates that can leverage something like newer metal. Given that a large chunk of the user base uses an iPhone from 1-2 years ago it simply makes sense to use this and abandon old SDK.

This makes me wonder though how Apple seems to deal with this for their core apps.

I'd love to know what exciting new features the developers of my bank auth app (also used as semi-mandatory ID in various services) have available to them now that they've let it break on my otherwise adequate phone.

Apple technically supports downloading legacy app versions, but the system is broken: it usually requires the app to be in your purchase history, and developers can opt to delete their old binaries entirely.

Maybe something the EU could enforce is requiring Apple to offer the 'last compatible version' prompt for all users, not just previous downloaders, ensuring older hardware isn't artificially artificially rendered useless for basic tasks.

Developers don’t want new users downloading old versions and increasing the population of older versions they have to support

They got the memo... directly from Apple that drops fully functional phones with their SDK updates, only giving you tiny crumbs of security update once in a while

The iPhone 11 - the oldest version supported by iOS 26 - was released in 2019. My iPad Air from 2019 barely runs iOS 26 with 3GB RAM. What do you expect Apple to do differently?

Not forcing apps to drop support of fully functional phones, especially over poorly designed visual gimmicks?

Imagine you don't upgrade to iOS 26 and don't lose out on any of the app updates?

No one is forcing apps to drop support. Apple has supported downloading the “last compatible version” since 2011-2012. And developers are free to support iOS 18. Why waste their time and resources when they know every iOS 19 user can upgrade to iOS 26?

Apple hasn't supported that, by the way, there are apps where you simply can't download the "latest compatible version" Also you can't "buy it" even for free apps, you must've tied it to your account before. And yes, it's also forcing by making it very hard to support older versions, see the side comment on SDKs.

they know every iOS 19 user can upgrade to iOS 26?

Because not every user does? Obviously?

And the few who don’t aren’t worth my limited resources.
