Answer 1

Your app is in a sandbox, which is not able to access anything outside of itself. Suppose your targeting jailbroken devices, this is another story.

Xcode will install your app into a sandboxed environment. You need to manually sign the app using ldid -S /YourApp.app/YourApp then copy it tom the devices /Applications directory.
