OS 7 and Clear
Modified on: Sat, Jun 15, 2013 at 2:58 PM
Some of the Clear team are in San Francisco for this weeks Apple Worldwide Developers Conference, and like all other Apple developers weve just received the first beta of iOS 7.
As pre-release software is subject to change, we dont support Clear on pre-release versions of iOS - this includes iOS 7 Beta 1. We are aware of some display issues in iOS 7 Beta 1, and believe them to be issues that Apple needs to address in future iOS 7 betas.
Well of course ensure that Clear is fully updated to work on iOS 7, however cannot offer guaranteed support for iOS 7 until it launches later this year.
If youve installed iOS 7 Beta 1 or later, please bear in mind that youre using software intended for testing purposes only and that apps (including Clear for iPhone) may not work as expected.
