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)

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