I just started to learn coding via Swift Playground. I found this level is quite challenging, and I'd like to learn how to optimize the code.

Swift Playground: Roll Right, Roll Left

func toggleorcollect() {
    if isOnGem {
        collectGem()
    } else if isOnClosedSwitch && isBlocked {
        turnLeft()
        toggleSwitch()
    } else if isOnClosedSwitch{
        toggleSwitch()
    }
}

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

while !isOnOpenSwitch{
    toggleorcollect()
  navigateAroundWall()
    }
