I’m extending my break from Python to see how far I can go with Swift before I need a change of scenery again.

‘Documentation and API Reference’ under Xcode’s help bar is absolutely useful for further reading on any topics. I did not realise the benefits until I got to ‘Set’ even though it was introduced earlier in the book. There are actually several operations and examples listed there that are not in it.

So, instead of myCities.isSupersetOf(yourCities), it should be myCities.isSuperset(of: yourCities).

I’m moving on to ‘Functions’ next. Wish me luck!
