protocol _Sequence_Type This protocol is an implementation detail of SequenceType; do not use it directly. Its requirements are inherited by SequenceType and thus must be satisfied by types conforming to that protocol.

Import import Swift Instance Methods func generate() Required Return a generator over the elements of this sequence. The generator's next element is the first element of the sequence.
