How to save a Seaborn plot into a file

The following calls allow you to access the figure (Seaborn 0.8.1 compatible):

swarm_plot = sns.swarmplot(...)
fig = swarm_plot.get_figure()
fig.savefig("out.png") 

as seen previously in this answer.

The suggested solutions are incompatible with Seaborn 0.8.1. They give the following errors because the Seaborn interface has changed:

AttributeError: 'AxesSubplot' object has no attribute 'fig'
When trying to access the figure

AttributeError: 'AxesSubplot' object has no attribute 'savefig'
when trying to use the savefig directly as a function

UPDATE:
I have recently used PairGrid object from seaborn to generate a plot similar to the one in this example.
In this case, since GridPlot is not a plot object like, for example, sns.swarmplot, it has no get_figure() function.
It is possible to directly access the matplotlib figure by:

fig = myGridPlotObject.fig
