// Why do you want a numeric version? Because number format is easier to use than string.
// For example, you may want to write a NSPredicate for Core Data fetch for different version:
// NSPredicate(format: "clientVersionNumber < %@", "2070500") // 2.7.5
// This gist assume the version digit is limitted to 4.

public static var versionString: String {
    return (Bundle.main.infoDictionary?["CFBundleShortVersionString"] as? String) ?? "1.0"
}

// Only support 4 digits, invalid string will return 0, longer digits will be dropped

# This script move files from an old directory into a new dirctory

# The purpose is to organize files in one place and do 'svn mv' after
