# init(randomSource:lowestValue:highestValue:)

Initializes a uniform random distribution with the specified lower and upper bounds, using the specified source randomizer.

## Declaration

```swift
init(randomSource source: any GKRandom, lowestValue lowestInclusive: Int, highestValue highestInclusive: Int)
```

## Parameters

- `source`: A randomizer that produces raw random values for use by the distribution. A randomizer is any object implementing the doc://com.apple.gameplaykit/documentation/GameplayKit/GKRandom protocol, which can be a random source algorithm such as the doc://com.apple.gameplaykit/documentation/GameplayKit/GKARC4RandomSource class or another random distribution.
- `lowestInclusive`: The lowest value to be produced by the distribution.
- `highestInclusive`: The highest value to be produced by the distribution.

## Return Value

Return Value A new random distribution.

## Discussion

Discussion A random distribution works by mapping the values produced by the source randomizer to the range and characteristics specified by the distribution. Multiple distributions can share the same source, with the side effect that retrieving a random value through one distribution affects the sequence of random numbers produced by the source.
