To support SWD programming, you can breakout GND, 3V3, SWDCLK and SWDIO. Take a look at our Open Source nRF52 board schematic:

Since the MCU is an ARM Cortex you need to use SWDIO/SWDCLK to program it, along with a VCC and GND connection. The pins for SWDIO and SWDCLK are fixed, so you need to use those.

As a side note. The SWD pins can't be used for anything else (unlike on some MCU's where SWD pins can be reconfigured by the Application to become GPIO)
