Cloud storage provider Box has announced compatibility with iOS 8 on day one, including support for iOS App Extensions, which allows apps to “lend” functionality with each other.

This means users can access Box content from any other app on their iDevice, provided it supports the Extensions framework. Users can select a document on Box and open it in an editor, or work on Box content from a mobile project management tool, for instance.

“This gives you unprecedented freedom and control when it comes to your information, while maintaining the security you expect with Box and iOS,” wrote Aaron Levie, Box CEO, in a blog post.

“This is a huge milestone for interoperability, and we’re thrilled to support iOS 8 on day one to transform productivity and collaboration for individuals, businesses and industries,” he added.

With the release of iOS 8 yesterday, plenty of companies have announced their support. Enterprise mobility management (EMM) provider MobileIron noted in a blog that iOS 8 was “the first sign of Phase III of mobile enterprise computing.”

In other words, we’ve moved on from only being able to do wireless email, and we’ve moved on from the more recent trend of using standalone apps for working on mobile. Now it’s about workflow. It was a point Levie referenced to close his blog.

“We’re just at the beginning of the post-PC technology shift, with many more years of innovation to come,” he wrote. “What Apple introduced [yesterday] is crucial to the health and success of this transition.”

Box is evidently ramping up its collaboration tools. Box Notes, a tool which allows users to compare notes across mobile, has recently been made available for both iOS and Android-powered devices.
