iOS actually has a full implementation of Scheme (TinyScheme) running inside the kernel, that manages the (often very complex) permission schemes -- one for each type of pre-installed app or daemon, and then one for the third-party apps as well.

Edit: Unrelated: I just realized you made the Treo 650 Linux version -- that was awesome!

This is one area where iOS rocks. Seriously, how difficult is it to make permission system granular?

I believe Android was the first to have fine grained app permissions where you could actually choose what an app has access to. iOS added that later.

This is one thing iOS does much better than Android. Apps don't request permissions until the moment they need them, instead of the entire laundry list at the installation time. This allows auto-updating of all apps, while still preventing permissions creep.

Huh? What does iOS have permissions and access control for?

Are you comparing the permission system iOS has today with the one Android had a decade ago?

iOS has permission explanations. I imagine this should probably carry over to macOS.

iOS has had runtime permissions for far longer than android :) Some apps will even explain what they (claim to) need the permission for before triggering the permission authorisation pop up.

That's exactly the same as iOS native permissions, isn't it?

How is the iOS permission system different here ?

AFAIK Android's current permission system is very similar to iOS's one with granular permissions granted at runtime for camera, contacts, etc.


Android also allows user to control permissions on per app basis. What does iOS do that Android doesn't?

As a user I want to have the app as isolated as possible and have the ability to grant it any system permissions I want. Perhaps combined with a store rule that an app isn't allowed to block unrelated functionality when it doesn't get the permissions it wants.

iOS has been quite good to me in this regard, although it still needs improvements (e.g. add a permission for accessing internet).


There are some pretty powerful permissions that apps can request. This allows interesting apps to exist that can't be done on iOS.

It's up to users to not install apps that request permissions they don't agree with, although that is indeed not presented ideally.


It did have them from the beginning, and the set of supported permissions was quite substantial compared to what iOS offered. But you're right, iOS was first to have the ability to grant/revoke individual permissions at runtime

Do what mobile OS do and make the app ask for permissions just before it needs to do something special. Make it impossible to ask for root. Sandbox apps.

Linux distributions package applications (including binary ones) for their users, why can't macOS or Windows do this? Run automatic safety checks on them before deploying updates to users. The Windows Store and Apple's App Store (on macOS) are kind of like that, but they only have applications that developers chose to put there. I don't see Linux distributions asking developers for permission to package their application (there are proprietary packages on Arch and NixOS), so I don't see why Apple couldn't do the same.

Certificates are a bureaucratic half-solution.


That's how Apple handles the iOS permission model, as I understand

And before iOS, J2ME phones had very fine-grained permissions (though it was usually the carrier that controlled them).

Apple does check for unreasonable entitlements (permission requests) in apps. And for other creepiness too. And I like it very much.

I think Apple users are underrepresented here, more developers here (and Android nutjobs, lol).


I agree. I was quite shocked myself and I also found the descriptions vague. I wasn't even sure what programs are accessing the data.

I really think iOS is the only OS has really done permissions right on the 3rd party level and on the OS level.


I like the screenshot in this post about the permissions Android apps ask for. At least this matches my experience. Android apps by and large just ask for everything so it's a choice between giving them everything or not being able to use them.

Apple OTOH does two major things different:

1. Apple's approach is to ask for individual permissions it needs when it first needs them. I can't overstate how much better this is than the Android all-or-nothing permission dialog.

2. Apple's permissions make more sense to users. Things like:

- Your location

- Run in background

- Your contacts

- Your photos

- The camera

Android's permissions always struck me as what engineers would do if they designed a permission system.

TRUE. Big true.

Honestly though I don't really see the author's point. I don't see iOS 14 and whatever the next Android version is to be back to what Symbian did.
