var count: Intvar first: Self.Element?var isEmpty : Boolvar underestimatedCount : Intfunc drop(while: (Self.Element) throws -> Bool) rethrows -> Self.SubSequence predicate returns true and returning the remaining elements.
predicateがtrueを返す間は要素を飛ばして残りの要素を返すことによって、ある下位シーケンスを返します。
func dropFirst (Int) -> Self.SubSequence func firstIndex (where: (Self.Element) throws -> Bool) rethrows -> Self.Index?func formIndex (inout Self.Index, offsetBy : Int)func formIndex (inout Self.Index, offsetBy : Int, limitedBy : Self.Index) -> Boolfunc formIndex (after: inout Self.Index)func makeIterator () -> IndexingIterator <Self>Iterator is IndexingIterator<Self> .
IteratorがIndexingIterator<Self> である時に利用可能です。
func map<T>((Self.Element) throws -> T) rethrows -> [T]func prefix(Int) -> Self.SubSequence func prefix(through: Self.Index) -> Self.SubSequence func prefix(upTo : Self.Index) -> Self.SubSequence func prefix(while: (Self.Element) throws -> Bool) rethrows -> Self.SubSequence predicate returns false and skipping the remaining elements.
predicateがfalseを返すまで冒頭の要素を含んでいて残りの要素を飛ばしている、ある下位シーケンスを返します。
func randomElement () -> Self.Element?func randomElement <T>(using: inout T) -> Self.Element?func split(maxSplits : Int, omittingEmptySubsequences : Bool, whereSeparator : (Self.Element) throws -> Bool) rethrows -> [Self.SubSequence ]func suffix(from: Self.Index) -> Self.SubSequence subscript<R>(R) -> Self.SubSequence subscript(Range<Self.Index>) -> Slice<Self>SubSequence is Slice<Self>.
SubSequence がSlice<Self>である時に利用可能です。
