Converting Optional String to Int in Swift 4

I'm trying to make a call from my JSON file where the variable is a string however in order to compare it I would want it to be an integer, however, whenever I try and convert it using methods on here nothing seems to be working, assuming the wrong syntax. This line essentially (pData.info?.nutriScore ?? 0) prints a score however its a string.

if let nScore = Int(pData.info?.myScore ?? 0) < 0 {
           //Other Code   
       }

Avoid using ?? default value ,

Yes you dont have the value in your object so you are passing the default that doesnt mean default value is your Real data .

    if let b = pData.info?.myScore, let nScore = Int(b) , nScore >= 0{
        print(nScore)
    } else {// handle negative logic}

You need

if let nScore = Int(pData.info?.myScore ?? "0" ) , nScore > 0 {

}

if let nScore:Int = Int(pData.info?.nutriScore ?? "0") {
        if nScore < 0 {
            print(nScore)
        }
    }
