Not sure if it matters but I did notice that it's removing build files for watchapp here: https://github.com/appcelerator/titanium_mobile/blob/master/iphone/cli/commands/_build.js#L5683 It unmarks the following product files: /Users/kiat/titaniumTestWatch/SGTestW/build/iphone/build/Products/Debug-iphonesimulator/SGTestW.app /Users/kiat/titaniumTestWatch/SGTestW/build/iphone/build/Products/Debug-iphonesimulator/SGTestW WatchKit App.app /Users/kiat/titaniumTestWatch/SGTestW/build/iphone/build/Products/Debug-iphonesimulator/SGTestW WatchKit Extension.appex However, the thing is, the watchKit apps are not in Debug-iphonesimulator but actually in Debug-watchsimulator. This has always been the same in iOS 9.3 and Titanium 5.4.X. So we having been rebuilding the watchkit project for every build. Not sure if it's by design. [~cbarber] fyi.

It's the same for non-watch applications. Just noticed it in hyperloop-examples with iOS 10 today. After running the build again, the error seem to be gone. Strange behavior.

Master PR: https://github.com/appcelerator/titanium_mobile/pull/8198 6_0_X PR: https://github.com/appcelerator/titanium_mobile/pull/8200 This PR fixes a number of Xcode 8 and WatchOS related issues: * Team id is now required in the tiapp.xml when building an app with a watch extension and Xcode 8. * Added build configuration settings for swift files in watch apps ** Namely set the "SWIFT_VERSION" to "2.2", if it's not already set... all new Watch extension projects will have this set to "3.0" * Removed old watchos2 template in favor of existing watchos2-objc template. * Set default min iOS SDK version to 8.0 if not explicitly set in the tiapp.xml and compiling using Xcode 8. * Removed old maintainers from package.jsons. The bad news is I was not able to reproduce the original issue in this ticket. Differential builds work just fine. The problem with the destination is due to a problem with selecting an iOS Simulator. I believe this to be machine/install specific issue where one of the simulators is mucked up.

I'll move Chris's PR to another ticket and resolving this one as not reproducible.
