Coding was 2nd fight. The first fight that I had to deal was to set up provisioning profile correctly so that I can test my app on my iPhone device. I do not have any hair left to pull out. (j/k) Seriously it should not be this difficult to comprehend how to set it up correctly. Follow this and this if you have an error like “ApplicationVerification Failed” when compiling your project and installing your app to iphone device. Those two links give the comprehensive guides to setting up your environment for developing and testing your app on your device.

A note: In iPhone SDK 2.2 there is no “Code Signing Provisioning Profile” column in the property anymore. Instead, it’s merged into Code Signing Identity as shown in the photo.
