Swift 3 - Cannot call value of non-function type 'XCUIElement'

I am trying to simplify my UITest code. At this time I have hundreds of lines of code for checking up to eight table rows each with three text fields. This will not only reduce the number of lines of code that I have, but it will reduce the erros that are caused by the copy/paste/edit process.

I am getting a "Cannot call value of non-function type 'XCUIElement'" error on the three lines in the checkRow function.

If I replace the 'thisRow' variable in the three lines with an integer, the code will compile.

Here is the before and after. 

func testAkcCh() {
    navConfig.tap()
    pickCD.adjust(toPickerWheelValue: "4")
    pickCB.adjust(toPickerWheelValue: "5")
    pickSD.adjust(toPickerWheelValue: "3")
    pickSB.adjust(toPickerWheelValue: "2")
    XCTAssert(app.tables.cells.count == 8)
    XCTAssert(app.tables.cells.element(boundBy: 0).staticTexts["Best of Breed"].exists)
    XCTAssert(app.tables.cells.element(boundBy: 0).staticTexts[p5].exists)
    XCTAssert(app.tables.cells.element(boundBy: 0).staticTexts[d13].exists)
    XCTAssert(app.tables.cells.element(boundBy: 1).staticTexts["Best of Opposite Sex"].exists)
    XCTAssert(app.tables.cells.element(boundBy: 1).staticTexts[p5].exists)
    XCTAssert(app.tables.cells.element(boundBy: 1).staticTexts[d06].exists)
}

into

func checkRow(thisRow: Int, thisAward: String, thisPoints: String, thisDefeated: String) {
    XCTAssert(app.tables.cells.element(boundBy: thisRow).staticTexts[thisAward].exists)
    XCTAssert(app.tables.cells.element(boundBy: thisRow).staticTexts[thisPoints].exists)
    XCTAssert(app.tables.cells.element(boundBy: thisRow).staticTexts[thisDefeated].exists)
}

func testAkcCh() {
    navConfig.tap()
    pickCD.adjust(toPickerWheelValue: "4")
    pickCB.adjust(toPickerWheelValue: "5")
    pickSD.adjust(toPickerWheelValue: "3")
    pickSB.adjust(toPickerWheelValue: "2")
    XCTAssert(app.tables.cells.count == 8)
    checkRow(0, "Best of Breed", p5, d13)
    checkRow(1, "Best of Opposite Sex", p5, d06)
}

This compiles, but defeated most of the benefit...

func checkRow(thisRow: Int, thisAward: String, thisPoints: String, thisDefeated: String) {
    XCTAssert(app.tables.cells.element(boundBy: 0).staticTexts[thisAward].exists)
    XCTAssert(app.tables.cells.element(boundBy: 0).staticTexts[thisPoints].exists)
    XCTAssert(app.tables.cells.element(boundBy: 0).staticTexts[thisDefeated].exists)
}

The function signature of the element(... function looks like:

func element(boundBy index: UInt) -> XCUIElement

The compiler is interpreting your 0 literal as the appropriate type for the context, which when passed directly is UInt. However, when passing 0 into checkRow, it interprets it as an Int since that is the type you specified for thisRow.

My guess is that you need to change the type of your thisRow parameter to UInt:

func checkRow(thisRow: UInt, thisAward: String, thisPoints: String, thisDefeated: String) {

Or alternatively, convert thisRow to UInt like:

XCTAssert(app.tables.cells.element(boundBy: UInt(thisRow)).staticTexts[thisAward].exists)
