Random Gems Everywhere

let totalGems = randomNumberOfGems

var gemCon = 0

func navigate () {
    while !isBlocked {
        moveForward()
        if isOnGem {
            collectGem()
            gemCon += 1
        }
    }
}

func turnOffPortals() {
    bluePortal.isActive = false
    pinkPortal.isActive = false
}
func turnOnPortals() {
    bluePortal.isActive = true
    pinkPortal.isActive = true
}

func turnAround() {
    turnRight()
    turnRight()
}

while gemCon < totalGems {
    navigate()
    turnAround()
    turnOffPortals()
    navigate()
    turnAround()
    turnOnPortals()
}

Here is my solution. I assume the Gems would appear on the edge as well, so I believe it is a more generic solution. But it always takes a long time to solve the puzzle. Don't know how to simplify it.

`
let totalGems = randomNumberOfGems
var countGem = 0

func navigate() {
if isBlockedRight && !isBlocked {
moveForward()
} else if !isBlockedRight {
turnRight()
moveForward()
} else if isBlocked{
turnLeft()
turnLeft()
}
}

func portalOpen() {
bluePortal.isActive = true
pinkPortal.isActive = true
}

func portalClose(){
bluePortal.isActive = false
pinkPortal.isActive = false
}

func collect(){
if isOnGem {
collectGem()
countGem = countGem + 1
}

}

while countGem != totalGems{
navigate()
portalClose()
collect()
navigate()
portalOpen()
collect()
}
