How can I remove values array based on array other [duplicate]

Answer 1

You can do with below options.

// Option 1 - Using Set's

let arrayOne : Set = [1,2,3,4,5,6,7,8]

let arrayTwo : Set = [1,2,4,5,6,7]

var result = arrayOne.symmetricDifference(arrayTwo)

print(result) // {3,8}

// Option 2 - Using Array

var result1 = [Int]()

for value in arrayOne
{
    if !arrayTwo.contains(value)
    {
        result1.append(value)
        }
    }

print(result1) // {3,8}
