The error code is 0x00000002, which means "SoftDevice has not been enabled". What issues can lead to this problem?

You should compare the returned error code with the errors listed above the function in the API documentation (the function can be found by using Find in Files).

/**@brief Enable External Interrupt.
 * @note Corresponds to NVIC_EnableIRQ in CMSIS.
 *
 * @pre{IRQn is valid and not reserved by the stack}
 *
 * @param[in] IRQn See the NVIC_EnableIRQ documentation in CMSIS.
 *
 * @retval ::NRF_SUCCESS The interrupt was enabled.
 * @retval ::NRF_ERROR_SOC_NVIC_INTERRUPT_NOT_AVAILABLE The interrupt is not available for the application.
 * @retval ::NRF_ERROR_SOC_NVIC_INTERRUPT_PRIORITY_NOT_ALLOWED The interrupt has a priority not available for the application.
 */
SVCALL(SD_NVIC_ENABLEIRQ, uint32_t, sd_nvic_EnableIRQ(IRQn_Type IRQn));

The returned error code will be in hexadecimal format, use "Go To Definition Of '...'" to find the error code of the different errors. You can use CTRL+- to navigate backwards.

Error code 0x2002 corresponds to NRF_ERROR_SOC_NVIC_INTERRUPT_PRIORITY_NOT_ALLOWED.

What happends if you change SWI_IRQn to SWI2_IRQn?
