Hi Hbucius, You can define your own `Array2D` type that uses a 1-dimensional array as backing (for fast performance) but exposes a high-level 2-dimensional array API.
Here’s a really primitive starting point I found on GitHub: https://github.com/raywenderlich/swift-algorithm-club/blob/master/Array2D/Array2D.swift <https://github.com/raywenderlich/swift-algorithm-club/blob/master/Array2D/Array2D.swift> Cheers, Jaden Geller > On Apr 18, 2017, at 11:39 PM, Saagar Jha via swift-evolution > <swift-evolut...@swift.org> wrote: > > It might be helpful if you showed a bit more of the code you’re working on, > so that we can better see what you’re trying to do.
