I still wonder how much it would have cost the FBI to crack the passcode/phrase on a phone with secure enclave. I also wonder if an agency like the NSA has capabilities around these devices and would they be willing to expose such capabilities in another similar scenario. A final musing of mine is if they wouldn't just claim some group or another did it for $X,000,000 dollars to make it all seem plausible (e.g. the cost and attack scenario on the 5c was plausible and probably required desoldering the storage, but that won't help on a device with the enclave system). The encrypted by default iOS 4 and the whole design around passcode handling in that release was the start of a very strong security posture for Apple and their iOS devices.

  Sadly, I can no longer update my comment, but please note that the iPhone 5S, 6, and 6+ are equipped with Secure Enclave. As recently as last April, the FBI was claiming they could not access 5S or newer models[1] (at least with the hack they reportedly bought for over $1 million[2]).

    I wouldn't trust the FBI as an accurate source of information about things like this.

  I don't see any mention of iOS versions there. Do they claim to support 10.3? Btw, these don't mention 6S or later models, or even the iPhoneSE. Guessing the exploits are dependent on chipset or older version of the OS.
