The invention relates to a method of operating a swing door, whereby a drive moves a door leaf from a first position of the door leaf to a second position of the door leaf. For providing an operation of the swing door in a more effective and/or efficient way the method is characterized in that the drive adds an additional driving force and/or torque to the door leaf in the first position and/or the second position of the door leaf in relation to an external driving force and/or torque acting on the door leaf to hold the door leaf in the first position or second position, respectively.
