Convert an array of Ints to a comma separated string

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

Solution

  • Well you can do it like :

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