xcode console log

i had used code give in sample app.

i unable recreate error.
make sure these steps you've taken:

1. import mobilefirst platform studio 7.0 "invoking adapter procedures in hybrid applications" sample project
2. right-click on adapter folder , select run > deploy mobilefirst adapter
3. right-click on project folder , select new > mobilefirst environment, add ipad environment
4. right-click on ipad folder , select run > xcode project
5. click run in xcode

for me, following above steps able run sample application in ios simulator = app displayed , feeds retrieved.
