You could also use something like the BlackMagic Probe, which runs on a STM32 and provides SWD via a GDB server implementation which appears as a USB Serial CDCACM device

I still don't fully understand what the question was about. @Badred: You are looking for a BLE module that can be integrated to your PCB that is easy to program ?

However, You better take a look on the bootloader feature. it is easier for You i think, cause no need for additional hardware

For daplink? There are schematics available on github, just google for swdap/daplink (daplink is the name of the firmware i think, SWDAP is the name for the hardware)...

is there any available schematic for it so I can directly design it as part of my PCB?

Daplink/SWDAP is the microcontroller with possibility of programming the chip by SWD. Other (probably better for you) solution if you want firmware update over-the-air is the bootloader provided by Nordic. It is described here, but it is quite outdated. You can find examples in newest SDK and more info on infocenter

@Wojtek Is it piece of hardware of software? Can you please provide anylinks. I was refering is to use only the SoC which has the bluetooth and the microcontroller inside our own PCB.

I am not sure I understand correctly, but if you need something to easily program nRF5x on the PCB board delivered to Your client, I would use DAPLINK. Cheap solution, just one additional chip, possibility to update firmware by usb.
