My theory on why they didn't elaborate on U1 / announce the (rumored) object tracking tags: they need better U1 chip penetration geographically before making any promises. Once a bunch of iPhone 11's are out there, they can further test the new product in a more realistic setting, and make adjustments if necessary. There could be some critical flaw that may need reengineering and they won't want a repeat of AirPower.

For instance, if they released the new object tracking tag with iPhone 11's, it would be a bad user experience because U1 is not spread out. Better to wait until the U1 geographically saturates to their standards before releasing it.

They can still talk about U1 in regards to e.g. new AirDrop capabilities, and in other marketing-level generalities.

I think it is something else.

The Xcode GM points towards an Apple AR devices. I think there could have been a "One More thing" in the Keynote, but it was pulled out in the last min along with All U1 announcement. They simply don't want Another AirPower to happen.

And it might have something to do with whether the software is ready for it as well, iOS 13.1 coming 10 - 14 days after the release of iOS 13.0. With quite a lot of features promised in WWDC missing, when was the last time we had something like this?

And may be they decided to save it for October event. After all we are still missing new MacBook Pro, New iPad Pro, Mac Pro update, and may be new iMac Pro?

That is actually a really good thought. I could see this being an additional feature in the new hardware; I'm guessing it's in the new Series 5 watch. Maybe this is a push for people to upgrade their computers as well as their phones.

There's an even more compelling reason why Apple's waiting a while before announcing the tracking tags: crowdsourcing.

At WWDC this year, Apple announced that all iOS devices would begin reporting nearby devices' locations back to Apple. U1 probably only works at relatively close range, so they want to wait until their "crowdsourcing network" includes enough devices for long-range tracking to work. (IIRC they aren't going to let users prevent their devices from contributing to the network, so it's just a matter of waiting until everyone has the latest iOS update.)

is that data privacy issue if we cannot opt out ?

Wired has a good article about how it works

A rotating scheme that makes it impossible for the wrong actors to track you.

It would be better if I could verify the code running on the device. You have to trust that Apple won’t track you. And hey, I trust Apple more than some unfriendly government, but I still have to trust Apple. If a big profitable unfriendly government asked them to track someone, what would Apple do?

> If a big profitable unfriendly government asked them to track someone, what would Apple do?

Presumably the exact same thing they'd have done if they hadn't rolled out this Find My feature. They designed it so Apple can't tell where your device is, which means if anyone wants to demand this info from Apple, then Apple has to implement that tracking separately, which they could do regardless of the Find My feature's existence.

If Apple had access to the device data themselves, then that's a huge problem because governments can reasonably start issuing warrants for that info. The fact that Apple doesn't have it means nothing has changed on the governmental front.

You’re presuming that Apple does not “have” our location data. I am making the claim that Apple could gain our location data if Apple wanted to. I think we are making different arguments. I don’t know if Apple has anyone’s location data. But if Apple decided to selectively enable the collection of some people’s location data, the iPhone 11 would offer them increased precision which other iPhone 11 users would unknowingly assist in collecting.

Why would an actor use Apple as a target vector? It is much easier to get location tracking thru the mobile service providers. They have the location data in real time and can’t deny that. It’s done thousands of times a day all over the world with and without a warrant. No vendor specific phone and no activation of special functions needed.

> Why would an actor use Apple as a target vector?

I can only speculate. But if I wanted someone’s location without making some noise, this increased precision would be nice to have over carrier’s coarse location data. Your GPS position could localize you to a building, but your UWB position could perhaps localize you to a room. And actually if the law enforcement agency had a device capable of detecting yours based on its UWB signal, they could find you very quietly.

Using current generation technologies like OTDOA and similar, cell carriers can already localize you to a room in a building in many cases.

Verizon can do down to around 10 centimeter accuracy with their LTE-M network in the best case (don’t have a link to support that handy, otherwise I’d share).

Or any third parties that you agreed to broadcast location data. We know the geo-location + time dragnet warrants are already used very widely with Google.

I'm not really sure how the U1 data is particularly relevant to governments. They don't generally need to know the precise movements of your phone about a single room. GPS will already locate you to the building and frequently to the room itself.

Most people underestimate the usefulness of location data. Do you can use location data to compute accurate credit scores? (better than what banks achieve). To predict health state?

The article talks how a device owner can opt-in, but there's this:

> A nearby stranger's iPhone, with no interaction from its owner, will pick up the signal, check its own location, and encrypt that location data using the public key it picked up from the [stolen] laptop

You can always opt out of any location use through the Location Services controls in Settings.

Thise location tags are going to be an incredible tracking asset to an eventual “AR map of the world”

> all iOS devices would begin reporting nearby devices' locations back to Apple

Just to clarify for others - its not that all iOS devices will report the location of all other devices, but rather "lost" devices will emit a (BLE?) signal, which nearby Apple devices will report its location back to Apple.

How would a lost device know it was lost? The Wired piece on this suggests that all devices are always broadcasting their location:

I'm trying to find sources, but its alluding me at the moment, but my understanding was that when a device is offline for long enough, it freaks out and starts emitting its key.
