Difference between UIAutomator and driver.swipe

UIAutomator is for Android only.
With UI Automator I can scroll and find element\elements with text\text contains\id\text starts with.
Searching for element via UIAutomator allows to actually scroll view up/down to the searchable element. First of all, it is a search action, you can use it for scrolling if you have a scrollable view and know element inside of it. So it requires:
View with scrollable=true attribute.
Know element id, text, etc. to locate it.
Can’t use coordinates.
Fails if element is not found.
Not precise, stops scrolling as soon as element is found.

• MobileElement firstClickableEl = driver.findElement(MobileBy.AndroidUIAutomator(“new UiSelector().clickable(true)”))
• MobileElement elementInView = driver.findElement(MobileBy.AndroidUIAutomator(“new UiScrollable(new UiSelector().scrollable(true).instance(0)).scrollIntoView(new UiSelector().text(“‘ + text + ‘”).instance(0))’)

driver.swipe is with x and y coordinates.
Actions API is used for different gestures like touch, tap, drag&drop, swipe, etc.

1. no need to locate elements
2. Can use both coordinates and elements
3. More precise if you pass the right coordinates

public void swipeScreen() {
    // final value depends on your app and could be greater
    final int ANIMATION_TIME = 200; // ms

    final int PRESS_TIME = 200; // ms

    int edgeBorder = 10; // better avoid edges
    PointOption pointOptionStart, pointOptionEnd;
    // init screen variables
    Dimension dims = driver.manage().window().getSize();

    // init start point = center of screen
    pointOptionStart = PointOption.point(dims.width / 2, dims.height / 2);
    pointOptionEnd = PointOption.point(dims.width / 2, dims.height - edgeBorder);

   TouchAction touch = new TouchAction(driver);
                touch.press(pointOptionStart)
                // a bit more reliable when we add small wait
                .waitAction(WaitOptions.waitOptions(Duration.ofMillis(PRESS_TIME)))
                .moveTo(pointOptionEnd)
                .release().perform();
}
