Why can't we delete app cache in iOS?

    Right now Twitter takes up 782MB on my phone. Of that 661MB is Documents & Data that can only be deleted if I remove the app and reinstall it. Many games on my phone take up hundreds of MB with Documents & Data. Why isn't there a way to clear this cache to free up space? I'd rather have that than deleting unused apps. My guess is app cache takes up more space than little used apps.

    Very good question. That would be a feature I'm looking forward to.

    Excellent question - this is a bit annoying to not have at the 11th iteration of the OS.

    I've been asking for this for a long time.

    It's poor design.

    A prior version of Periscope was an 80MB or so App that was taking up Gigs of space on my iPhone, resulting in the delete & reinstall loop you mention.

    Thankfully they've since updated it at their end, so it's not as bad.

    This remains a significant issue though overall.

    I agree. We should submit this as feedback. It needs to happen.

    iOS does it on its own when you are running low on space

    Because regeneration of cache takes battery life. Plus, some of those caches are automagically cleared when the device is low on space. Heck, we at least can use the optimise storage features, and you can even offload apps in iOS 11.

    Plus you can force a cache flush in iOS by pressing and holding the power button until you see slide to power off then release power key and hold home button until returned to home screen your entire cache is now flushed.

    That's the opposite of what's being asked for. Those options are "Remove the app but keep documents and data" and "Delete the app and all data". In English, the options are "Offload App" and "Delete App".

    It may not be in iOS yet, but the Twitter app added this not too long ago. Go to Settings>Settings and privacy>Data usage and in the Storage section you can select Media Storage or Web storage and Clear media storage.

    That's not the same thing the OP was referring to. Two totally different things.

    Twitter has a cache deleting feature on iOS.

    There are a few apps on the App Store that do this. I don't know if they work in iOS 11, but they definitely do in iOS 10.3.2. Magic cleaner is one of them.

    Also submit feedback to the app developer. iOS allows developers to choose whether downloaded media is stored in persistent or temporary caches. Clearly, media downloaded when viewing tweets, for example, should be temporary.

    That clears the RAM I believe, not the cache.

    That clears the web and media caches... I wonder if there are any hidden app caches present that are why Apple doesn't let us clear the caches.

    If you try to download a big movie from the iTunes Store, iOS will automatically delete quite a lot of cache! Try it with Titanic or something as big.

    Because iOS is supposed to be smart at managing cache for apps. It's supposed to clean up cache folders once in a while when space is needed, but I've never found it functional.

    Cache improves performance for apps and the OS, but also greatly eats up storage that can be used for more useful things.

    Needless to say, Apple needs to implement something like this.

    But you actually want to see such a feature being build into iOS by Apple.
    Also I've tried all of them I think but unfortunately they don't actually work for e.g. clearing the cache for e.g. the Facebook app. I've also seen cases where the app size even got bigger after clearing then before.

    Some apps such as a few video apps (Infuse, nPlayer) or news apps (Newsify) do have a cache clearing feature mainly to delete offline video, music (CloudBeats Pro), news.
