No, to exchange from ARC to SWT you will either need to use the automatic conversion tool or use the instructions provided here to complete the conversion process manually.

Tokens sent directly to the Swarm City token contract will NOT be converted, and can not be recovered.

DO NOT SEND ANY TOKENS DIRECTLY TO THE SWARM CITY TOKEN CONTRACT.

ARC token burn address: https://etherscan.io/token/0xAc709FcB44a43c35F0DA4e3163b117A17F3770f5?a=0x0000000000000000000000000000000000000000

Once the conversion process is complete, you will be able to view your newly minted SWT on your MyCrypto account as well as in the Terminal.
