While I am not against the idea, I believe that this is not as easy as one would think as everyone has a different understanding of the word "random" as most of random generators aren't "true" random generators.
I think this would ideally require a new protocol RandomGenerator which would be passed to the collection to get the random element, i.e. it would look something like: arr.randomElement(using: ARC4RandomGenerator()) > On Mar 4, 2017, at 6:55 AM, Jonathan Hull via swift-evolution > <swift-evolution@swift.org> wrote: > > This is a small improvement, but I still think it is worthwhile. > > I would like to see an 'init(randomIn: Range<Self>)’ added to Numeric (where > Comparable), which would return a random number in the given range.
