When this code is executed, how many items will the
names array contain?
var names = [String]() names.reserveCapacity(2) names.append("Amy") names.append("Rory") names.append("Clara")
Correct answer: 3.
reserveCapacity() method is there to let you give an indication of how many elements you intend to store in an array, but it does not place any sort of limit.
