- the calucaltion should be over when I dismiss the modal sheet- once the calculation is over the results are used by the table view only in this view controller. There is a button in the same view controller that segue to a third view controller and plot the results in a graph but it does not get triggered unless you press the button to segue to the graph- yes PdArray is created by self.pipelyKitAlgorithmCHECK () at line 87, then this function calls another function that clears PdArray and refill it ( append it) with adjusted values. This last PdArray version gets used in the tableview.the last function that spits out PdArray and gets called by self.pipelyKitAlgorithmCHECK () is this function and it not inside the DisptachQueue brackets :func pipelyKitAlgorithemFinal () {
