Hi,

since iOS16, my app has a huge performance problem. Generating the map overlay now takes about a minute on an iPhone 12 Pro (before iOS16 about 3s). In my app I have hundreds of different MKPolygons which are colored different. For each Polygon an individual MKOverlay is generated. I actually know, that this might be the problem (hundreds of overlays), but I don't know how to merge all the polygons with one color in one single mkoverlay.

Does anyone has a hint how to do this or an other idea how to solve this issue?

OK, found our, that MKMultipPolygon should be the right way. I have to restructure my app a bit to check out, if this increases the performance.

I'm also having this issues, and all started on iOS 16.

I'm also having this issue. I improved the way I render and decreased the number of polygons that I'm drawing, but the problem is still happening, not so often but still happening.
