291405750 MDU6SXNzdWUyOTE0MDU3NTA= 1855 swap_dims should support dimension names that are not existing variables 1217238 closed 0     3 2018-01-25T00:08:26Z 2020-01-08T18:27:29Z 2020-01-08T18:27:29Z MEMBER      

Code Sample, a copy-pastable example if possible

python input_ds = xarray.Dataset({'foo': ('x', [1, 2])}, {'x': [0, 1]}) input_ds.swap_dims({'x': 'z'})

Problem description

Currently this results in the error KeyError: 'z'

Expected Output

We now support dimensions without associated coordinate variables. So swap_dims() should be able to create new dimensions (e.g., z in this example) even if there isn't already a coordinate variable.
