Apple published developer documents recently that may have revealed what the iWatch looks like, it's claimed.

Apple is expected to launch a smartwatch or wearable device called the iWatch on 9 September. Although many reports have said the iWatch will boast a flexible sapphire screen, tiny sensors, and other things, not much has surfaced about the design or form factor. Until now.

Design firm Punchkick Interactive has shared a developer document from Apple that mentions a "media remote" alongside a symbol that resembles a wearable with a round watchface. It's a rudimentary illustration of course but could still reveal the overall shape of Apple's anticipated iWatch.

The document, published for the first time on 4 September, also shows a symbol for an iPhone, described as a "media source". Apple therefore doesn't mind using its own products as illustrations. We can therefore assume the smartwatch symbol represents a real Apple product that has yet to be unveiled.

There is one problem with this theory though: Apple has apparently used the smartwatch symbol in the past, as noted by Punchkick Interactive, indicating the symbol might just be a simple placeholder. Check out Pocket-lint's round up for more information about what Apple could show off next week.
