Hi there,I have an app in xcode and i can do builds with a direct iOS device (a physical iPhone 6s Plus) and xcode builds the app and pushes it to the device.. awesome.however the next step for me is to get it on testflight and to do this my understanding is that i must go to product / archive to build an uploadable file. I am told to select "generic ios device" when doing this so I do but get the error. "Build system informationerror: (my app) has conflicting provisioning settings. (my app) is automatically signed for development, but a conflicting code signing identity iPhone Distribution has been manually specified. Set the code signing identity value to "iPhone Developer" in the build settings editor, or switch to manual signing in the project editor. (in target '(my app')"everything i try to tweak in there doesn't seem to matter. Anyone dealt with this before?
