Check in "System" view whether the debug option is not set to gpio.
Found it. Fixed.
Many thanks to you and the community. I am new to using this community for answers.

I have same problem, but in PSOC Creator 4.2 :-(
I donot find debug option :-(
Can you help me, please.
In Creator window "Workspace Explorer" (Left hand side) under Design wide Resources, double click on "System". There you'll find the debug option to change the pins to SWD instead of GPIO.
