Tara AI — Build better software, faster
Apple today announced several significant changes to the iOS developer agreement, and a new document called the App Store Review Guidelines. The latter is intended as a plain-English guide to the rules and guidelines Apple is using to determine which apps to accept into the store — a guide that has been sorely lacking to date.
These documents are only available to registered iOS developers, however, so here’s a look at some of what’s new.
This is the section that was changed a few months ago, with the release of iOS 4.0, to ban the use of third-party developer tools. In the 4.0 version of the agreement, section 3.3.1 read (italics added):
In today’s updated agreement, the entire italicized section has been removed. There’s no longer any mention of specific programming languages, nor any prohibition against “intermediary translation or compatibility layers”. This means, I believe, that tools such as Adobe’s Flash cross-compiler are no longer banned from use. If you can produce a binary that complies with the guidelines, how you produced it doesn’t matter.
3.3.2 An Application may not itself install or launch other executable code by any means, including without limitation through the use of a plug-in architecture, calling other frameworks, other APIs or otherwise. Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application.
3.3.2 An Application may not download or install executable code. Interpreted code may only be used in an Application if all scripts, code and interpreters are packaged in the Application and not downloaded. The only exception to the foregoing is scripts and code downloaded and run by Apple’s built-in WebKit framework.
I don’t think this new language is a change in policy. It’s just a shorter, more direct explanation. So, for example, games that include a Lua interpreter are OK, but only if they use the Lua interpreter to run scripts that are hard-coded into the app bundle itself — it can’t be used to interpret script that users can download or install later. This change in language matches the de facto policy that has been applied by the App Store reviewers.
3.3.9 You and Your Applications may not collect, use, or disclose to any third party, user or device data without prior user consent, and then only under the following conditions:
The collection, use or disclosure is necessary in order to provide a service or function that is directly relevant to the use of the Application. For example, without Apple’s prior written consent, You may not use third party analytics software in Your Application to collect and send device data to a third party for aggregation, processing, or analysis.
The collection, use or disclosure is for the purpose of serving advertising to Your Application; is provided to an independent advertising service provider whose primary business is serving mobile ads (for example, an advertising service provider owned by or affiliated with a developer or distributor of mobile devices, mobile operating systems or development environments other than Apple would not qualify as independent); and the disclosure is limited to UDID, user location data, and other data specifically designated by Apple as available for advertising purposes.
3.3.9 You and Your Applications may not collect user or device data without prior user consent, and then only to provide a service or function that is directly relevant to the use of the Application, or to serve advertising. You may not use analytics software in Your Application to collect and send device data to a third party.
Again, shorter and sweeter. The language that seemed written specifically to ban AdMob — the mobile ad network purchased by Google, a purveyor of mobile operating systems — has been removed.
That’s it for the significant changes to the developer license agreement.
This new document is written in remarkably casual language. For example, a few bullet items from the beginning:
We have over 250,000 apps in the App Store. We don’t need any more Fart apps.
If your app doesn’t do something useful or provide some form of lasting entertainment, it may not be accepted.
If your App looks like it was cobbled together in a few days, or you’re trying to get your first practice App into the store to impress your friends, please brace yourself for rejection. We have lots of serious developers who don’t want their quality Apps to be surrounded by amateur hour.
We will reject Apps for any content or behavior that we believe is over the line. What line, you ask? Well, as a Supreme Court Justice once said, “I’ll know it when I see it”. And we think that you will also know it when you cross it.
If your app is rejected, we have a Review Board that you can appeal to. If you run to the press and trash us, it never helps.
This is a living document, and new apps presenting new questions may result in new rules at any time. Perhaps your app will trigger this.
Some examples of rules that were enforced, but never previously codified:
10.4 Apps that create alternate desktop/home screen environments or simulate multi-app widget experiences will be rejected
10.5 Apps that alter the functions of standard switches, such as the Volume Up/Down and Ring/Silent switches, will be rejected
And some interesting ones:
2.11 Apps that duplicate apps already in the App Store may be rejected, particularly if there are many of them
3.10 Developers who attempt to manipulate or cheat the user reviews or chart ranking in the App Store with fake or paid reviews, or any other inappropriate methods will be removed from the iOS Developer Program […]
11.11 In general, the more expensive your app, the more thoroughly we will review it […]
14.1 Any app that is defamatory, offensive, mean-spirited, or likely to place the targeted individual or group in harms way will be rejected
14.2 Professional political satirists and humorists are exempt from the ban on offensive or mean-spirited commentary
(Not sure why “professionals” qualify for an exemption here, nor what it is that qualifies someone as a “professional”.)
The existence of this document is a very welcome change, and it goes a long way to answering much of the criticism regarding prior controversial App Store rejections, by putting in writing the rules that are actually used by the reviewers.
