The app works fine in the simulator, builds and runs.
When I attach my device (iPhone 3GS running iOS 4.3) and target the iPhone, the result is "Build failed" with "No issues".
Looking at the build results window, everything is green, has a checkmark, including the Build failed notice.
Expanding the transcripts show no errors.
I cannot exclude the possibility of a signing or provisioning error, but it gave me those errors, I ironed them out, and now it's not giving me any errors or issues, just "Build failed; No issues"
I've been getting 'Build Failed' with no errors in the Issue navigator(only warnings). Report navigator, though, displayed errors correctly.
