iOs Build and run does not automatically run the game

Previously when I build the iOs game using Build and Run, the XCode application would build the game and it was launched automatically on my iPhone device. Now, it just builds and I have to click on the Run icon in XCode to start it on my iPhone device. Does anybody know what I am doing wrong? Has this to do with XCode, SDK or Unity upgrades? Any tips welcome! Thanks.

As mentioned here, “XCode 4.0 “Build & Run” support.”
