led and switchs program failure Tiva C board

I'm trying to run this code on TIVA C board. sw2 connected to PF0, sw1 connected to PF4 and RGB LED connected to PF1, PF2 and PF3.

When I press sw2 it shall turn the led blue and if sw1 is pressed it shall turn the led green otherwise it shall be red.

The code doesn't function properly. I hope you can point out what I did wrong.

/*************************

#define RCGCGPIO (*((volatile unsigned long*)0x400FE608)) //CLOCK
#define PORTFDATA (*((volatile unsigned long*)0x400253FC)) //DATA
#define PORTFDIR (*((volatile unsigned long*)0x40025400)) //DIRECTION
#define PORTFDEN (*((volatile unsigned long*)0x4002551C)) //ENABLE
#define PORTFLOCK (*((volatile unsigned long*)0x40025520)) //LOCK (lock or       unlocks PF0)
#define PORTFCR (*((volatile unsigned long*)0x40025524)) //COMMIT (uncommit PF0)
#define PORTFPUR (*((volatile unsigned long*)0x40025510)) // PULL UP resistor
#define PORTFPDR (*((volatile unsigned long*)0x40025514)) // PULL Down resistor
/*************************/
int sw1;
int sw2;
int delay;
int main (void)
{
   RCGCGPIO = 0x20; //Enable clock for PORT F
   delay = RCGCGPIO;
   PORTFLOCK = 0x4C4F434B; // unlock commit reg
   PORTFCR   = 0x01; // unlock PF0
   PORTFDEN  = 0x1F; //Enable pins 0 to 4
   PORTFDIR  = 0x0E; // pins 0 and 4 input - pins 1,2,3 output
   PORTFPUR = 0x11;

   while (1)
   {
      sw2 = PORTFDATA & 0x00000001; 
      sw1 = PORTFDATA & 0x00000010;

      if (sw1 == 1)
         PORTFDATA |= 0x00000002;

      else if (sw2 == 1)
         PORTFDATA |= 0x00000004;

      else
         PORTFDATA |=  0x00000008;
   }
}

Here are two obvious problems with your code. There are probably more...

You set sw1 = PORTFDATA & 0x00000010, so the only possible values sw1 can have are 0x10 or 0x00. Then you test if (sw1 == 1). But this test will never be true because sw1 can never equal 1.

You use the |= operator to set the bits of PORTFDATA. But nowhere do you ever clear the bits of PORTFDATA. So your LEDs may turn on but they will never turn off.
