Initializers
init()Creates a vector with zero in all lanes.
init<S>(S)Creates a vector from the given sequence.
init(arrayCreates a vector from the specified elements.
init(from: Decoder)Creates a new vector by decoding scalars from the given decoder.
init(repeating: Bool)A vector with the specified value in all lanes.
Instance Properties
var description: StringA textual description of the vector.
var hashThe hash value.
var indices: Range<Int>The valid indices for subscripting the vector.
var scalarThe number of scalars, or elements, in the vector.
Type Properties
static var scalarThe number of scalars, or elements, in a vector of this type.
Instance Methods
