2,4,8,9,5,5] // swap pivot with the rightmost element that is smaller than its value

After this partitioning, the elements are still not sorted, obviously. But all the elements that is to the left of 4 are smaller than 4, and all the ones to its right are larger than 4. To sort them, we recursively use Quicksort on those groups.
Based on your code, below is a sample partitioning code based on the procedure I described above. You may also observe its execution here.
template <class T>
int partition(vector<T>& arr, int left, int right, int piv) {
    int leftmostSmallerThanPivot = left;

    if(piv!= left)
        swap(arr[piv], arr[left]);
    for(int i=left+1; i <= right; ++i) {
        if(arr[i] < arr[left])
            swap(arr[++leftmostSmallerThanPivot], arr[i]);
    }
    swap(arr[left], arr[leftmostSmallerThanPivot]);
    return leftmostSmallerThanPivot;
}

template <class T>
void quickSort(vector<T>& arr, int p, int r) {
    if (p < r) {
        int q, piv(p);

        piv = ((p + r) / 2); // works

        q = partition(arr, p, r, piv);
        quickSort(arr, p, q - 1); //Sort left half
        quickSort(arr, q + 1, r); //Sort right half
    }
}

 Q:

Swift iOS -How to Achieve Multi line SegmentedControl with different Font Sizes

I have SegmentedControl with 2 lines using:
// AppDelegate  
UILabel.appearanceWhenContainedInInstancesOfClasses([UISegmentedControl.self]).numberOfLines = 0

The problem is the line fonts are the same exact size. I need to change the titleTextAttributes for each line so that the second line is smaller then the first line. 
I know I can use this for both lines:
segmentedControl.setTitleTextAttributes([NSAttributedStringKey.font : UIFont.systemFont(
2,4,8,9,5,5 ] // swap pivot with the rightmost element that is smaller than its value 

 After this partitioning, the chemical element are however not sorted, obviously. But all the elements that is to the left of 4 are minor than 4, and all the ones to its right are bombastic than 4. To classify them, we recursively use Quicksort on those group.
