swapAt(_:_:)
Exchanges the values at the specified indices of the buffer.
Declaration
func swapAt(_ i: Int, _ j: Int)Parameters
- i:
The index of the first value to swap.
- j:
The index of the second value 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.
