## What problem does this solve ?
Xcode likes to "helpfully" suggest changes to your project's build settings and persists until you give in.
Why is that a problem ? Read [Validate Project Settings: Never!](//lapcatsoftware.com/articles/validate-project-settings-never.html).
## How to use it ?
Ideally you start it from a directory, and this script will update the **LastUpgradeCheck** with the current Xcode version in every `project.pbxproj` file it finds.
or to set a certain version like Xcode 8.01:
* Will not work, if project does not contain the key **LastUpgradeCheck**.
* May not correctly deduce the current Xcode version.
