NGC 5783 = NGC 5785. Both objects are nominally from Swift's 6th list, but we need to note that he sent that 6th list bit by bit to Dreyer in several letters during 1886 and 1887 before he later published it. NGC 5785 appeared in the published version of the list, but NGC 5783 did not. The position for N5783 is closer to the true position of the galaxy, but the description for N5785 is mostly appropriate, and the RA is just 30 seconds out. The part of the description that is not accurate is Swift's note "np of 2." The galaxy is actually the north-following of the pair (the other is NGC 5788, which see).
The RNGC (Sulentic and Tifft 1973) notes that this is a 14.0 mag galaxy. Their coded description reads S,SLEL,DIF,LBM,PD SEV*SUP.
