If you have resaved your branch settings, your build no longer uses xcrun  to generate an .ipa  file; it uses xcodebuild  instead. Xcodebuild , unlike xcrun , doesn't allow generating an .ipa  file if the build is not signed; unsigned builds produce an .xcarchive  instead. If you wish to generate an .ipa  file with the artifacts of an unsigned build, you can use the .xcarchive  file to do so.
