:-1: [App名] has conflicting provisioning settings. [App名] 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 '[App名]')
解決策
Xcode > File > Project Setting... で、Shared Project Settings: の Build System を「Legacy Build System」に変更したら無事に実行できました。
