Need to generate
Save For Ad Hoc Deployment
To save for Ad Hoc Deployment, you need to add an Apple ID account that is enrolled in the iOS Developer Program for the development team 'xxxxxxxxxx'
Finally found a way for creating
.ipa build with xcodebuild command.
Show in Finder.
You can see
.xcarchive file in Finder.
This will save
.ipa on Desktop.
xcodebuild -exportArchive -exportFormat ipa -archivePath <FILE_NAME>.xcarchive -exportPath ~/Desktop/<FILE_NAME>.ipa
Still looking for better solution, don't know why Apple removed this feature from Xcode 6 :(
