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.
Update: it's fixed!
I have submitted a bug to Apple. They have replied that they are aware of the problem and have people looking into it. They will contact me when they have resolved the issue. I'll post an update here when they do.
