Swipe is one of the basic functionality in any mobile application and in order to automate the mobile application the swipe functionality should be successfully implemented.

Appium has a wide range of libraries and a method to swipe the screen is also present in its library.

swipeScreen(startX, startY, endX, endY, duration)

startX: This is the starting X axis in pixel ie the location from we want to initiate the swipe functionality.
startY: This is the starting Y axis in pixel ie the location from we want to initiate the swipe functionality.
endX: This is the ending X axis in pixel ie the location from we want to end the swipe functionality.
endY: This is the ending Y axis in pixel ie the location from we want to end the swipe functionality.
duration: The amount of time in millisecond to hold the screen while performing the swipe functionality.

If we have to swipe from top to bottom then the value of Y axis remains same and only the value of X axis will change.

If we have to swipe from left to right then the value of X axis remains same and only the value of Y axis will change.
