skip(by:)
Advances the position of this iterator by the specified offset, or until the end of the underlying type’s elements.
Declaration
mutating func skip(by offset: Int) -> IntReturn Value
The number of items that were skipped. If the returned count is less than maximumOffset, then the underlying type did not have enough elements left to skip the requested number of items. In that case, the iterator’s position is set to the end of the underlying type.
