swift pair item from 2 array

How would it be possible in swift to pair number with the same index? as you have seen in the code below there were 2 set of array . when code runs i want to assign first index of devices to lbNum1.text and first index of devices1 to lbNum2.text and then next would be next index and so on.for example lbNum1.text = 1 and lbNum2.text = 2 and it will set random again to lbNum1.text = 2 and lbNum2.text = 3 until in reach to the end

code

    lbNum1.text = String(randomItem)
    lbNum2.text = String(randomItem1)
    //the value of this 2 must be with the same index lbnum1 will ge data from device and lbnum 2 will get the from device1   
    they shoudl get data from the same index


        let devices = [1, 2, 8, 7, 6]
        let randomIndex = Int(arc4random_uniform(UInt32(devices.count)))
        let randomItem = devices[randomIndex]
        print("random item:" ,randomItem)

        let devices1 = [2, 3, 2, 9, 3]
        let randomIndex1 = Int(arc4random_uniform(UInt32(devices1.count)))
        let randomItem1 = devices[randomIndex1]
        print("random item:" ,randomItem)
