Trying to upload a binary, which includes a watch app. The error I'm getting (which I wasn't getting a couple days ago) is the value provided for LC_VERSION_MIN_IPHONEOS for the watchkit extension is 8.2 which is greater than the maximum allowed value of 10.3... apparently 8.2 > 10.3?
I'm updated to the latest XCode, 8.3, that didn't fix the problem. Tried changing the iOS deployment target for the watch app and extension, no apparent effect on the message.
I too had the same issue. Removed the watch app and did the upload. It has been accepted for review. So looks like the issue is with the validation of the watchkit extension. Will submit the app again with the watch app once this issue has been taken care of by Apple.
Apple fixed this bug yesterday. You can use the same binary. There's no need to make any changes.
