Now available for testing apps on the iPhone Duo!

Here are some screenshots from getting my own app compiled, if anyone is interested:

I'm just gonna ignore this thing and continue as if it never existed. Worked with Vision Pro that no body uses and will work with this.
yieldcrv•37m ago
taking the Apple strategy with the Apple ecosystem, genius
devin•35m ago
I'm not fangirling over it, but comparing it to Vision Pro is ridiculous.
matsemann•17m ago
But will you gain anything by building for it? Will you see noticeably more users or people choosing another alternative because you didn't specifically building the app for Duo? At least if it doesn't outright break.
BiteCode_dev•12m ago
It is exotic, and bring only a little to the table for a stiff price increase.
Razengan•32m ago
I had the 1st-gen Vision Pro, and then sold it.

I really wanted to use it as my primary computing display, but as is almost always the case with Apple, the amazing hardware was hamstrung by the crippled OS.

Even just being able to use it as a generic display i.e. with a Nintendo Switch would have been amazing.

It is indeed a niche product. Its price reflects the sales expectations of Apple.

But its form factor has been validated for almost a decade now from other manufacturers. So iPhone Duo will do fine. It will not surpass a slab iPhone but fine.

Vision Pro was a completely new beast, the hardware was not there, the market was not there.

The price, hardware, and market was not there for the Vision Pro. There was no reason to buy a VR headset that couldn’t play games.

> Its price reflects the sales expectations of Apple.

People famously said that of the first iPhone, expensive at the time.

Then about the $1k iPhone X.

Apple have made phones a fashion accessory and status symbol. I won’t be surprised if the Duo sells extreme well, even by iPhone standards.

selectodude•18m ago
My only concern is that they'll sell out so quickly for so long that I'll have to wait for the iPhone Duo Two-o because they won't be easy to get until like May 2027.

> It is indeed a niche product.

It's worth noting that "niche" in this case means ~10M in its first year, comparted to an estimated 250M Apple smartphone shipments in 2027. So far, Apple has sold ~600K Vision Pro in total.

Also, supporting Duo is not an enormous lift if you're already supporting resizable windows, as developers are required to do for OS 27.

busymom0•27m ago
Developer here. Apple often rejects app submissions if the app doesn't look optimized for some iPhone device or iPad device. So won't be surprised if they reject new apps and updates for not being optimized for the Duo. This could be their way of getting developers to comply.
devin•22m ago
That seems like a tough road. They've never been able to enforce that iPhone app makers build an iPad-compatible version or vice versa, and this looks exactly like that scenario.
CharlesW•4m ago
As of OS 27, Apple is requiring iPhone apps to function on iPad in iPhone-compatibility mode. Setting the target to iPhone-only does not prevent iPhone apps from running on iPad, apps must support resizability, and apps can no longer deliberately detect iPad and refuse to run (the only exception being apps with a legitimate iPhone-only hardware dependency).
isodev•24m ago
It really feels quite irrelevant. Also, the amount of work to support this with zero support from Apple since WWDC is just absurd. And even if one does the work, Apple will just sherlock the cool features into their apps.
nozzlegear•17m ago
Why does it feel irrelevant? And what kind of support should Apple be providing beyond releasing Xcode and an iPhone Duo simulator?

I presume this Xcode 27.1 beta will not want to launch on our Mavericks Forever, the last Mac OS we actually like and use.
CharlesW•10m ago
Correct.
ar_lan•6m ago
I think this is my main hesitation with picking up the Duo on the first release. I have no doubt the build quality is exceptional, but the chance that the apps I use are not well optimized for this new form factor is pretty high in the first year of its release.

I don't think they won't work, but I anticipate oddities to appear for a while, especially for older applications.

inshard•6m ago
Waiting for my coding agent to have zero idea what I mean when I say build for iPhone duo (due to knowledge cutoffs in pre-training; happened when Liquid Glass came out previously).
fg137•2m ago
The form factor of Vision Pro has also been validated for a decade from other manufacturers.

And that means nothing. Because other manufacturers are not doing well either.

Android 17 is the first since 3.x to add new APIs without releasing to the AOSP
