WebYou can use methods like initialize (repeating:count:), initialize (from:count:), and moveInitialize (from:count:) to initialize the memory referenced by a pointer with a value or series of values. Initialized Memory Initialized memory has a value that can be read using a pointer’s pointee property or through subscript notation. WebThe initialization of a dynamic array creates a fixed-size array. In the following figure, the array implementation has 10 indices. We have added five elements to the array. Now, the underlying array has a length of five. Therefore, the length of the dynamic array size is 5 and its capacity is 10. The dynamic array keeps track of the endpoint.
