I know that if I want to convert an array of Ints to a String, I do this:

[0,1,1,0].map{"\($0)"}.reduce(""){$0+$1}

but I cannot figure out how would I convert an array of Ints to a comma separated String

Well you can do it like :

let formattedArray = ([0,1,1,0].map{String($0)}).joined(separator: ",")
