Hi,
I know this isn't relevant to the Appery.IO however, I designed my app on it and exported to the Xcode in order to submit iTunes.
I keep getting same error messages from the Apple no matter how many times I was trying to fix it;
Invalid Image Path - No image found at the path referenced under key "CFBundleIcons": 57.png
Invalid Image Path - No image found at the path referenced under key "CFBundleIcons": 114.png
Invalid Image Path - No image found at the path referenced under key "CFBundleIcons": 72.png
Once these issues have been corrected, go to the Version Details page and click "Ready to Upload Binary." Continue through the submission process until the app status is "Waiting for Upload." You can then deliver the corrected binary.
