I'm looking at the schematic for the ISP_BLE_DS1507, specifically the reference designs page, and I'm a little confused as to what these pins mean. Why are OUT_ANT and OUT_MOD connected? Presumably OUT_ANT is antenna, but what does OUT_MOD mean? The pin description has it listed as RF ourput (I guess a typo for output)? Is this the output signal for the internal antenna? What are SWDCLK and SWDIO-nRESET? The pin description page doesn't offer much info as to what they actually do.
Thank you for anyone who can help me!

Have you googled what SWD means?

SWD stands for Serial Wire Debug. The pins are used for programming and debugging your code when running the IDE (integrated development environment).

Thanks for your answer! So are they just for connecting to the development board and for flashing the chip or do they serve some other purpose in the circuit. Is there any reason I would actually need them beyond just uploading my program to the board?
Thanks,
