Bitwise operations alter binary strings at the bit level. These operations are incredibly basic and are directly supported by the processor. These few operations are necessary in working with device drivers, low-level graphics, cryptography, and network communications. This section provides useful k...

This topic outlines how and when the Swift runtime shall allocate memory for application data structures, and when that memory shall be reclaimed. By default, the memory backing class instances is managed through reference counting. The structures are always passed through copying. To opt out of th...
