I have an app on the store for which I want to start rewriting the entire application "from scratch". When I try to build and execute the new app on my device (iPhone 4) which already contains the old app I get the error: "Could not change executable permissions on the application."
The new executable works ok if I run it on the simulator or delete the current application on the device and install fresh. My concern is people upgrading to this latest version of the app won't be able to.
How do you handle this scenario?
