9 iOS beta update appeared today for a good part of the users of the public beta versions of the operating system, but everything seems to have been just a problem generated by an alert sent prematurely by the company Apple Lossless Audio CODEC (ALAC),.
Considering that only three days separate us from iPhone 6S presentation, it is unlikely that Apple will release any beta version until then, considering that iOS 9GM it will most likely be offered, so if you see a similar message on your iPhone or iPad, you don't have to worry.
Apple has also sent erroneous update messages for OS X in the past, so problems of this kind are as normal as possible and should not concern you that much of the time.
