Iterating can be done as in @Rachel's answer. However there are different ways of doing the same thing, and not necessarily by iterating - and in some cases with just one line of code.

If you want to find, then the best way is using the array's filter method - but before that the multi dimensional array should be flattened, using flatMap.

So, to find the first element having a certain name, you can simply do:

let result: Person? = array.flatMap { $0 }.filter { $0.name == "Masha" }.first
