xcode 5 issues

hi, i got 7 issues when i build/run my app in xcode 5. here is an image of what i got :

1- Should i change it ?
2- I don’t know what to do
3- i solved it by changing manually the icons (solved)
4- i tried this link text but when i save and run it, it appears again

So should i solve that issues before submitting to the App Store ? What solution to use ?

ps : Game for iPad, Target ios version 4.3.


Hey, I get the Validate Project Settings error most of the time, It usually causes problems if you follow Xcode’s advice and automatically validate the settings. Usually I leave it as it is, and continue to Build the project.
