Apple has today announced that it will no longer ban the use of third party developer tools for iOS apps. As long as the app does not download any code the relaxing of the rules will allow apps to be created using Adobe Flash and other third party tools, expanding the potential number of developers exponentially.
In particular, we are relaxing all restrictions on the development tools used to create iOS apps, as long as the resulting apps do not download any code. This should give developers the flexibility they want, while preserving the security we need.
Earlier this year Apple banned the use of third party tools to help port apps from the likes of Adobe's Flash, Sun's Java, or Microsoft's Silverlight. At a similar time Adobe announced that the new Creative Suite 5 would include an application to assist in the porting of apps to the iPhone from Flash. Following Apple's announcement, Adobe abandoned the software.
At the time Steve Jobs wrote that, "We cannot be at the mercy of a third party deciding if and when they will make our enhancements available to our developers".
Apple has also published "App Store Review Guidelines" [PDF] to help developers the review process and allow the creation of successful apps for the App Store.
Apple's full statement:
The App Store has revolutionized the way mobile applications are developed and distributed. With over 250,000 apps and 6.5 billion downloads, the App Store has become the world’s largest mobile application platform and App Store developers have earned over one billion dollars from the sales of their apps.
We are continually trying to make the App Store even better. We have listened to our developers and taken much of their feedback to heart. Based on their input, today we are making some important changes to our iOS Developer Program license in sections 3.3.1, 3.3.2 and 3.3.9 to relax some restrictions we put in place earlier this year.
In particular, we are relaxing all restrictions on the development tools used to create iOS apps, as long as the resulting apps do not download any code. This should give developers the flexibility they want, while preserving the security we need.
In addition, for the first time we are publishing the App Store Review Guidelines to help developers understand how we review submitted apps. We hope it will make us more transparent and help our developers create even more successful apps for the App Store.
The App Store is perhaps the most important milestone in the history of mobile software. Working together with our developers, we will continue to surprise and delight our users with innovative mobile apps.
