title: iOS SQLite.swift, regarding upgrade of app?
body: <p>Regarding the magnificent and amazing SQLite.swift, I'm wondering</p>
  
  <p>You have an app in the app store, v7.  There's an upgrade to v8.  User X does upgrade v7 to v8 using the app store.</p>
  
  <p>Say in v8, we have slightly changed one of the sql tables, perhaps add a column or rename a column.</p>
  
  <p>Should anything or must anything special be done in SQLite.swift in this case? </p>
  
  <p>What's the SQLite.swift way to handle that?</p>
  
  <p>(In for example, Android there's a handy <a href="https://developer.android.com/reference/android/database/sqlite/SQLiteOpenHelper.html#onUpgrade(android.database.sqlite.SQLiteDatabase,%20int,%20int)" rel="noreferrer">onUpgrade</a> concept in their <a href="https://developer.android.com/reference/android/database/sqlite/SQLiteOpenHelper.html" rel="noreferrer">helper class</a> ... which comes with it's own set of complex issues.)</p>
