Map size for MapKit JS on mobile
Hello, This code works fine for desktop, but it's very difficult to display user location, map type controls for mobile. The map's existence depends on the height property only. The controls depend on the width one. Although the algorithm is not clear. I see that the width must be more or equal to display width. It works for portrait, but not for landscape. How to get stable appearance of the controls for any cases? I used iPhone SE 1.

How to know when Map is done painting after create
I've noticed bugs when you attempt to modify a map (set region or other things) immediately after creating the map. I noticed that if you load mapkit, wait 5 seconds then create a map, it makes about 5 network calls, downloads a js file, and runs some javascript. I have an issue where I have to do some loading after the map is fully ready, and may need to destroy the original map. To make a test of this, try creating a map then immediately call destroy and unmounting it. It'll produce a bunch of not defined errors as it's still trying to set up the map you just destroyed How do I know that the map that was created is ready and done with all the work it was doing? When is it safe to destroy that map? I found there is a property called map._impl.state that will be Initialized or Ready. But when it gets to Ready it is still not fully done loading, a destroy there will still cause errors. Is there an event listener or any wa

Hybrid Map displays oddly in Simulator
When displaying an Apple map within my app, the standard and satellite types of a fully zoomed-out view of North America both display perfectly on the Xcode Simulator, but the hybrid type is very different. The hybrid map shows up as a image with a dark gray background, with the names of the cities in the correct places, but only showing a jagged red line for some of the edges of the continents. Zooming in does not help. If I can find a way to post an image, I'll do so. I'm running Xcode version 7.0.1 (7A1001) on OS X Yosemite 10.10.5. Within Xcode, my deployment target is iOS 9.0 -- the problem still persists if i switch to iOS 8.0. Haven't gotten to the point where I can run the app on an actual device yet.

Reply to Will this app's plan pass the review?
What makes your app any different to, say, just using a Maps app that has those locations listed? When I search Apple Maps for restaurants, it shows restaurants near me. Would it do the same thing your app wants to do? If your concept cafés don't show up in Apple Maps, it's likely that Apple objects to that sort of content, and they wouldn't allow an app. Any app has to have some functional use to its users. If you're just surfacing a list of cafés, then it offers nothing new.

Incorrect 5.1 / Atmos channel mapping on Apple TV 4K (2022)
I ran 5.1 audio tests in both YouTube and Apple Music, and I noticed that when sound is supposed to play from the rear or front surround speakers, it’s also duplicated in the front left and right channels. I’m absolutely sure the issue is with the Apple TV, because I played the same video directly through my TV’s native system, and the channel separation was correct. Everything used to work perfectly before, so this must be a software issue. I’m currently on tvOS 26 Developer Beta 5, but I’m certain the problem also existed on the stable tvOS 18.5. I’ve already reset and updated my Apple TV, and I also tried switching the audio format to forced Dolby Atmos 5.1. On the forums, I mostly see complaints about Dolby Atmos not working at all — in my case, everything technically works, but not the way it’s supposed to.

Class Activation Maps with CoreML
Hi, I am trying to build a simple image classification app. I have a trained model using Keras and have it converted to an MLModel. Basing on the sample app in the CoreML documentation, I can use my model to classify a given image. But i would also like to visualize how model gives the classification. Is there a way I can show class activation maps along with the predictions in the app? Thanks!

iOS26 UINavigationController swipe from middle on maps causing issue
I have a UINavigation controller which on the second viewController has a Google Map view. In iOS 18 you would navigate normally around the map, and swipe your finger from the left side of the screen to move the map, this worked correctly. However, in iOS 26 swiping from left to right from anywhere but the far right side of the screen will cause the UI to try to pop the viewController. This does not happen when I add Apple Maps or other map frameworks to the VC. Is there a way to disable the swipe from middle in iOS 26?
