iOS 7 To Be Launched On September 10

September 10 is the date we’re currently marking in the diaries for the iPhone 5S and 5C reveal, and that may have just been reinforced by a claim that we’ll see the release of iOS 7 that very same day.
According to an email sent to developers from Nuance, the company behind Siri, the general availability date for iOS 7 is set for September 10.
The Next Web contributing writer Owen Williams posted the below email from Nuance to his personal blog, it reads:

As you are probably aware, iOS 7 GA will be released on September 10th.The NDEV Program has pre-qualified that SpeechKit 1.4.5 works properly on iOS 7, but we encourage you to conduct own testing to ensure that when the upgrade happens, your Nuance speech services continue to work seamlessly.

It asked developers using its API to conduct testing to ensure that their services work on iOS 7 even though its SpeechKit 1.4.5 is pre-qualified to work properly on iOS 7. Nuance is the voice recognition focused company which has also worked on Siri, Apple’s intelligent voice assistant.
Historically, Apple has released iOS Golden Master versions to developers on the same day as the announcement of new iPhones, giving developers time to test their apps with the final version of the new iOS before its release it to the general public a couple of days before the launch of the new iPhone.
