XCodeでipaの出力がうまく行かない時に、最新っぽいarchivesからipaを無理やり生成するスクリプト

build.sh

ipa_base="debug"
ipa_ext=".ipa"
profile="iOSTeam Provisioning Profile: *"

archives="/Users/$USER/Library/Developer/Xcode/Archives/"
newest_dir=`ls -lt $archives|head -n 2|tail -n 1|cut -f 13- -d " "`
echo $newest_dir

newest_ipa=`ls -lt $archives$newest_dir|head -n 2|tail -n 1|cut -f 13- -d " "`
echo $newest_ipa

filename=${ipa_base}_${newest_dir//-/_}${ipa_ext}
echo $filename

xcodebuild -exportArchive -archivePath "$archives$newest_dir/$newest_ipa"\
    -exportProvisioningProfile "$profile" -exportPath ./$filename
