Ask HN: Any good Swift training courses in London?

Hi UK people,<p>Work give us a training budget of around £500, it&#x27;s a use it or lose it situation.<p>As an iOS developer I thought an advanced Swift course might get me out the office for a few days ;)<p>Does anyone know of any decent courses like that in London? Preferably in person, during weekdays and not too far in the future.<p>- I&#x27;m open to other suggestions on how to spend the training money (no conferences though), user interface stuff could be quite interesting too.<p>Thanks!
