Scroll until element is visible iOS UI Automation with Xcode 7

You should extend the XCUIElement’s method list. The first method (scrollToElement:) will be called on the tableView, the second extension method helps you decide if the element is on the main window.

extension XCUIElement {

    func scrollToElement(element: XCUIElement) {
        while !element.visible() {
            swipeUp()
        }
    }

    func visible() -> Bool {
        guard self.exists && !CGRectIsEmpty(self.frame) else { return false }
        return CGRectContainsRect(XCUIApplication().windows.elementBoundByIndex(0).frame, self.frame)
    }

}

The scrolling code should look like this (e.g. scrolling to last cell):

func testScrollTable() {
    let app = XCUIApplication()
    let table = app.tables.elementBoundByIndex(0)
    let lastCell = table.cells.elementBoundByIndex(table.cells.count-1)
    table.scrollToElement(lastCell)
}

Swift 3:

extension XCUIElement {
    func scrollToElement(element: XCUIElement) {
        while !element.visible() {
            swipeUp()
        }
    }

    func visible() -> Bool {
        guard self.exists && !self.frame.isEmpty else { return false }
        return XCUIApplication().windows.element(boundBy: 0).frame.contains(self.frame)
    }
}
