TIL that Swift's UInt16 also supports operators for "wrapping arithmetic" when adding or subtracting potentially causes integer overflow/underflow

Screencap of a Swift REPL session showing:

• a variable `foo` being defined as a UInt16 with value 0xffff
• `foo` being "wrap-incremented" by one
• `foo`'s value is now 0x0000
• `foo` being "wrap-decremented" by one
• `foo`'s value is now 0xffff again
