にするとPGでプロジェクト作った後に File > Project Settings... > Build System を Legacy Build System にするだけでビルドが通るはず.

Legacy Build System が選ばれた状態にするためには

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>BuildSystemType</key>
    <string>Original</string>
</dict>
</plist>

を ProjectName.xcodeproj/project.xcworkspace/xcshareddata/WorkspaceSEttings.xcsettings として保存すれば良さそうなのだけど恐らくPGの中身をいじらなきゃなので我慢.
