Function to find the annotations that intersect with an array of selections using Apple's PDFKit in iOS

	func annotationsIn(selections: [PDFSelection]) -> [PDFAnnotation] {
	if selections.count == 0 { return [] }
	var results: [PDFAnnotation] = []
	for selection in selections {
	//See if rect matches the annotations in this page
	let page = selection.pages.first!
	let bounds = selection.bounds(for: page)
	for annotation in page.annotations {
	if bounds.intersects(annotation.bounds) {
	results.append(annotation)

This function converts a Google Maps V3 (Javascript API) of MVCArray of lats and longs (MVCArray<LatLng>) to Well Known Text (WKT). The result will be something like POLYGON((50 0, 0 20, 10 10, 50 0))

	function MVCToWKT(arr){
	var result = 'POLYGON(';
	for(ring = 0; ring < arr.length; ring++) {
	var strRing = '(';
	for(i = 0; i < arr.getAt(ring).length; i++) {
	strRing += (i > 0 ? ", " : "") + arr.getAt(ring).getAt(i).lng() + ' ' + arr.getAt(ring).getAt(i).lat();
	}
	//Add the first point to the end to close polygon
	strRing += ', '+arr.getAt(ring).getAt(0).lng() + ' ' + arr.getAt(ring).getAt(0).lat();
	strRing += ')';
