MLNMapViewDelegate on 6.8.0 doesn't work

[seraph3b]

Describe the bug

on 6.8.0 mapViewWillStartLoadingMap, mapViewDidFinishRenderingMap and mapView(_ mapView: MLNMapView, didFinishLoading style: MLNStyle) did not be fired even map appears (guess also mapViewDidFailLoadingMap and so on don't work)

To Reproduce
After loaded a style, map appears but app get stucked waiting for didfinishrenderingmap to continue

Expected behavior
delegate fired

Platform information (please complete the following information):

• OS: ios 18.1
• iOS
• map libre 6.8.0

Please provide a minimal reproduction.

I tried to reproduce this, but I was unable.

@seraph3b Can you provide the style this is happening with? Do you see any errors logged?

[seraph3b]

we have 5 different maps and this issue happens with every maps.
only "func mapView(_ mapView: MLNMapView, didFinishLoading style: MLNStyle) {" is fired (tryed on simulator and phisical devices with ios 18+ or ios 15+)

currently using xcode 16.1, swift package manager -> maplibre 6.8.0

with 6.7.1 it works as expected after setting style (self.mapView.styleURL = URL(string:"our map url")), map is loaded and fired:

• func mapView(_ mapView: MLNMapView, didFinishLoading style: MLNStyle) {
• func mapViewDidFinishRenderingMap(_ mapView: MLNMapView, fullyRendered: Bool) {

[louwers]

Thanks.

I'm investigating the issue.

I added these delegate methods to the AnimatedLineExample.swift and used AWS Open Data Standard Light and they fired as expected.

Could you share your style (can be private on Slack) so I can give it a try?

[seraph3b]

here you are @louwers https://tiler.3bmeteo.com/api/maps/bright_v2/style.json

[louwers]

Can you share your code?

This works for me

    func mapView(_ mapView: MLNMapView, didFinishLoading style: MLNStyle) {
        print("Map loaded")
    }
    
    func mapViewDidFinishRenderingMap(_ mapView: MLNMapView, fullyRendered: Bool) {
        print("Map rendered $fullyRendered")
    }

[seraph3b]

on viewdidload:
self.mapView.styleURL = URL(string:"https://tiler.3bmeteo.com/api/maps/bright_v2/style.json")
self.mapView.clearsContextBeforeDrawing = true
self.mapView.maximumZoomLevel = maximumZoomLevel
self.mapView.minimumZoomLevel = minimumZoomLevel

        // se CurrentRadar == swiss_radar limita al nord!
        let sw = CLLocationCoordinate2D(latitude: 35.07638, longitude: 6.402696)
        let ne = CLLocationCoordinate2D(latitude: 47.10169, longitude: 18.5499)
        self.bounds = MLNCoordinateBounds(sw: sw, ne: ne)

        self.mapView.cameraThatFitsCoordinateBounds(self.bounds, edgePadding: UIEdgeInsets(top: 20.0, left: 20.0, bottom: 20.0, right: 20.0))
        
        self.mapView.delegate = self

// other stuff not related to maps

then I wait for
func mapView(_ mapView: MLNMapView, didFinishLoading style: MLNStyle) {
and
func mapViewDidFinishRenderingMap(_ mapView: MLNMapView, fullyRendered: Bool) {

[louwers]

Could you try passing the style to MLNMapView to see if that makes a difference?

        mapView = MLNMapView(frame: view.bounds, styleURL: URL(string: "https://tiler.3bmeteo.com/api/maps/bright_v2/style.json"))

[seraph3b]

I have a mapView object inside a xib, so self.mapView is a weak outlet to that, I can't set as you suggested

[seraph3b]

It's not an option even I change a lot of code because I need to change style at runtime

[seraph3b]

maybe it's something useful, I set style inside this:
MLNOfflineStorage.shared.setMaximumAmbientCacheSize(102400) { error in
// style set here
}
