iOS Swift Collections and Control Flow Control Flow With Conditional Statements Working With Switch Statements

Why can't I use the function += within my switch rather than an append command?

I was testing and producing the correct results using the append function like this: europeanCapitals += [value], but the code did not pass. I eventually changed to using the .append function and it worked. Is there any reason for this or why the += is incorrect?

Do you have some code of the way you were doing it before ? For these empty arrays to append to them you have to use the append method and dot notation.
