Make unit test wait for an asynchronous call inside another method

Question

I am testing that all my data is loaded correctly in UIViewControllerusing UITableView.

The code that loads the data and populates the table is inside myMethod()and its asynchronous call.

func myMethod() {
    reloadModel { ... wait for async callback ... }
}

In my test case, I am calling myMethod(), but I do not know how to wait for the completion of the asynchronous call.

//Test Code
func testLoadData() {
        let listVC = ListViewController.init(tableView:tableView)
        listVC .myMethod()
         ... here it should wait for the async call...
        XCTAssertEqual(...)
}
