Instance Methodswift 6.0.1Swift
initialize(from:)
Initializes memory starting at this pointer’s address with the elements of the given collection.
This declaration was obsoleted in Swift 5.0: it will be removed in Swift 5.0. Please use 'UnsafeMutableBufferPointer.initialize(from:)' instead
func initialize<C>(from source: C) where Pointee == C.Element, C : Collection Parameters
- source
A collection of elements of the pointer’s
Pointeetype.
The region of memory starting at this pointer and covering source.count instances of the pointer’s Pointee type must be uninitialized or Pointee must be a trivial type. After calling initialize(from:), the region is initialized.

Type members
init(UnsafeMutablePointer<Pointee>) Creates a mutable typed pointer referencing the same memory as the given mutable pointer.
init?(UnsafeMutablePointer<Pointee>?) Creates a mutable typed pointer referencing the same memory as the given mutable pointer.
init(mutating: UnsafePointer<Pointee>) Creates a mutable typed pointer referencing the same memory as the given immutable pointer.
init?(mutating: UnsafePointer<Pointee>?) Creates a mutable typed pointer referencing the same memory as the given immutable pointer.
static func allocate(capacity: Int) -> UnsafeMutablePointer<Pointee> Allocates uninitialized memory for the specified number of instances of type
Pointee.
Instance members
var hashValue: Intvar pointee: PointeeReads or updates the instance referenced by this pointer.
subscript(Int) -> Pointee Reads or updates the pointee at the specified offset from this pointer.
func deallocate() Deallocates the memory block previously allocated at this pointer.
func deinitialize(count: Int) -> UnsafeMutableRawPointer Deinitializes the specified number of values starting at this pointer.
func initialize(from: UnsafePointer<Pointee>, count: Int) Initializes the memory referenced by this pointer with the values starting at the given pointer.
func initialize(repeating: Pointee, count: Int) Initializes this pointer’s memory with the specified number of consecutive copies of the given value.
func initialize(to: consuming Pointee) Initializes this pointer’s memory with a single instance of the given value.
func move() -> Pointee Retrieves and returns the referenced instance, returning the pointer’s memory to an uninitialized state.
func moveInitialize(from: UnsafeMutablePointer<Pointee>, count: Int) Moves instances from initialized source memory into the uninitialized memory referenced by this pointer, leaving the source memory uninitialized and the memory referenced by this pointer initialized.
func moveUpdate(from: UnsafeMutablePointer<Pointee>, count: Int) Update this pointer’s initialized memory by moving the specified number of instances the source pointer’s memory, leaving the source memory uninitialized.
func pointer<Property>(to: KeyPath<Pointee, Property>) -> UnsafePointer<Property>? Obtain a pointer to the stored property referred to by a key path.
func pointer<Property>(to: WritableKeyPath<Pointee, Property>) -> UnsafeMutablePointer<Property>? Obtain a mutable pointer to the stored property referred to by a key path.
func update(from: UnsafePointer<Pointee>, count: Int) Update this pointer’s initialized memory with the specified number of instances, copied from the given pointer’s memory.
func update(repeating: Pointee, count: Int) Update this pointer’s initialized memory with the specified number of consecutive copies of the given value.
func withMemoryRebound<T, E, Result>(to: T.Type, capacity: Int, (UnsafeMutablePointer<T>)throws Executes the given closure while temporarily binding memory to the specified number of instances of the given type.
