I've seen some reports of it also becoming available for iOS, but it seems to come and go between minor version upgrades and I'm not sure what the current status is.
Not an iOS developer; what does available mean in this case? Are you talking actual OS support, or simply that Apple has never approved any app attempting to do it? Because Safari obviously does it so my thinking is the OS must support it, but I guess Apple has a policy not to approve it.
Apps that want to JIT need an “entitlement” from Apple (in other words they have a signature from Apple that the operating system validates before letting the APIs work). So the OS supports it, Apple grants that entitlement to Safari so it can use it, but no third party app can get this entitlement.
But surely once "sideloading" (I hate that term, we used to just call it "installing"...) is enabled, apps not installed through the App Store will be able to utilise this entitlement?
Hope so. There should be some developer capability somewhere. And we should build for the reasonable good future, & show whats possible. Not what we can mete from the iron mailed fist of Cupertino in the real world if this or that, but what actual good is.
It'd be a mean spirited system to simply mark everything no-execute, always forever in any env. But that'd be distinct Apple flavored. Think Different, R.I.P..
