Ios – distribute the App for any device without UDID

iosipaprovisioning-profileudid

I've been searching stackoverflow, reading in the various blogs to get answer to my question "Can I distribute my app to someone, without getting his device UDID?"

The answers I found is all about "NO! You must have the list of UDIDs"

BUT, I've people (private company) telling me that they used to install apps without giving their device UDIDs to developer. Developer used to send them .ipa file, they just drag&drop it in itunes, that's it! I'm dizzy..

By which way they did it without UDIDs? (I'm against jailbreak, it's not option)

Or, maybe they're lying?

Best Solution

"Private company". There's the clue.

App store developers can only distribute apps to (up to 100) devices with known UDIDs. That's the $100 plan most of us have. We can only create signing profiles for ad-hoc distribution to our 100 devices, or for sending to Apple. ([eta:] Or, now, for time-limited distribution to specific AppleIDs through the new Apple TestFlight.)

There also exists the enterprise developer program, a $300 annual plan open to businesses (currently, any business with a DUNS number; the requirements used to be more stringent.) Enterprise developers can't submit to the app store, but they can sign apps for installation onto any device, without knowledge of UDIDs.

The enterprise developer contract includes an agreement not to install such apps on devices not associated with the organization or business. Devices do verify the signing certificate with Apple, so if you try to sell enterprise-signed apps to the public, Apple will notice and shut you down. Also, enterprise provisioning profiles expire annually, so devices have to be refreshed with new profiles or the apps stop working.

[Edit to add, later:] A third, excellent, option (really just a feature of the first) is the B-2-B App Store. We've found this to be a much better fit for most user cases where we had been setting up enterprise accounts for clients before. It works almost the same as regular app store distribution, except that the app isn't public - it's visible only to a list of client AppleIDs that you, the developer, specify on upload. Those clients, who must sign up with Apple Business Manager (it's free), may then "purchase" as many copies of the app as they want, in the form of redemption codes, and distribute them to end user devices however is convenient.

It's very slick. Watch the WWDC video on it (a little outdated now but it'll give you the gist). B2B apps may cost anything you like, including $0. Downloads and updates use the normal app store mechanisms. Redemption codes may be assigned by device instead of by AppleID if the client uses Apple Configurator to provision their devices. There are some limitations but they aren't onerous. Highly recommended.
