swapAt(_:_:)
Exchanges the byte values at the specified indices in this buffer’s memory.
Declaration
func swapAt(_ i: Int, _ j: Int)Parameters
- i:
The index of the first byte to swap.
- j:
The index of the second byte to swap.
Discussion
Both parameters must be valid indices of the buffer, and not equal to endIndex. Passing the same index as both i and j has no effect.
