I can not add any images to ios simulator. I tried saving from google images and tried dragging the images to photos app in the simulator but no image appear in my photos app. There are only 5 sample images.
My iOS simulator is 8.1 and same problem in all simulators(iphone 6, 5s,4s)
Go to
~/Library/Application Support/iPhone Simulator/User/Media/DCIM/100APPLE/
…and add Dog.THM and Cat.JPG.
~/Library/Application Support/iPhone Simulator/6.1/Media/DCIM/100APPLE
~/Library/Application Support/iPhone Simulator/7.0/Media/DCIM/100APPLE
This might help you.
