extension for adding multiple lines:

extension MKAnnotationView {

    func loadCustomLines(customLines: [String]) {
        let stackView = self.stackView()
        for line in customLines {
            let label = UILabel()
            label.text = line
            stackView.addArrangedSubview(label)
        }
        self.detailCalloutAccessoryView = stackView
    }



    private func stackView() -> UIStackView {
        let stackView = UIStackView()
        stackView.axis = .vertical
        stackView.distribution = .fillEqually
        stackView.alignment = .fill
        return stackView
    }
}

using:

view = MKPinAnnotationView(annotation: annotation, reuseIdentifier: identifier)
view.canShowCallout = true
view.loadCustomLines(customLines: ["qqqq", "wwww", "eee"])
