This technical article dives into the memory layout of value types in Swift. It explains fundamental concepts like bits, bytes, and words in a 64-bit architecture, and discusses memory alignment, access efficiency, and potential crashes from misaligned data. It demonstrates using Swift's MemoryLayout to inspect the size, stride, and alignment of types like Bool and Int.
