Hi Jaden Geller, Saagar ,
Thanks for the reply and advice. Array2D is really faster than the
default two dimension. But I think as a general language, Swift should
provide default efficient ways for multiple dimension array.
I found this problem when I write an algorithm. It is a DP problem
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:

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. Is there any operation in
particular that is slow?
Also, CC’ing swift-users since I think it belongs there.
