When upgrading to XC7 GM form XC 6.4, it had an option to upgrade project to recommended settings. I run it. It was about moving to WatchOS 2 and also several settings regarding $(PRODUCT_BUNDLE_IDENTIFIER)
Afterwhile, I discarded project changes because I had to test on WatchOS 1 before.
This discard was a mistake since Xcode non longer propose automatic upgrade of settings.
How to manually redo those settings change:
- switch to WatchOS 2
- $(PRODUCT_BUNDLE_IDENTIFIER) stuff
