I know there have been a few other people asking this question, but my situation is a bit different.
I'm getting this error whenever I build my app. I've tried looking at the .plist file that is generated and there isn't a value for the MinimumOSVersion key. My app runs just fine on the iPhones we test with, but for the life of me, I can't figure out what is causing the .plist to be set incorrectly.
Can anyone shed some light on this? I'm not sure what other info to post besides I'm building against 4.0 and targeting 3.2, building for both iPad and iPhone, and building for both arm6 and arm7.
Thanks, Robbie
MinimumOSVersion is supposed to be based on your iPhone OS Deployment Target. Check that setting in your target's build properties to confirm that it's set to 3.2.
Even if it appears to be set properly, try changing it to something else and then changing it back to 3.2 at so that the value is explicitly set within your target build settings. I've encountered an Xcode bug in the past where my MinimumOSVersion was getting set to a different value than my iPhone OS Deployment Target. Explicitly setting the value in my target settings resolved the issue for me.
