strange phenomenon after build and run

hi i have a game in development, however i changed the name of the app as well as the bundled identifier in player setting. so when i build and run i get two of the same game but with different name. and what is weird is that after i have updated the name xcode compiles and runs, it compiles the game under the new game, but runs the older version of my game using another game. What is wrong here? Do i have to update game info in the info.plist as well???

SOLUTION: delete ALL copies of your app off the device (all your devices while u are at it)… and re-deploy…

as a general rule for ME… if i mess with the info.plist file… i delete all copies of the app on all devices before deploying again.

(i know the question is old…but it still happens on iOS in 2013).
