Xcode 9 iOS Playgrounds and iOS Simulator is Unusable with MapKit

So, we all agree that Xcode 9 simulator is crap. We all filed at least one bug report, right?

Apple, is there anybody in there?

I too am having the same problem. I filed a bug as well.

Same here. Project has SKTileMapNodes and simulator is unuasble at 1 FPS .I had a spectrum 128k which was faster. Apple STOP making new fancy hardware and fix the BUGS in the development software !!!!😠

It is unbelievable this issue has continued into the GM build. This is a crippling issue for developers of map-based apps.

This work around does not help. Filed radar://34517122

Super annoying. Very hard to develop an app with a MKMapView in it. Also having issues with the GM build.

This is still happening on the build that was released today. We use Mapbox which seems to have the same problems as MapKit

Just downloaded XCode 9 today, which I would think is the release candidate, or even release version...simulator is indeed unusable, and not just for MapKit 😟

There is a latency for every gesture, or mouse click. Testing longpress is impossible.

Yep, exactly. Just rebuilt a game app I was in the midst of developing to run on the iPad simulator and can't believe how horribly slow the images update. At least it was reasonably smooth in the last version. Very disappointing.

Updated to Xcode 9, the simulator became completely unusable for SpriteKit development. We are not talking frames per second anymore; we are literally talking seconds per frame. Several of them.

Additionally, the newest tvOS became incapable of rendering SceneKit objects in SpriteKit. They work in the simulator and on iOS devices, but not on the tvOS device. (Such SceneKit objects simply don't appear. Nothing of them is rendered.) I can't figure out a reason for this, and it has broken our game.

Confirmed here too. Downloaded GM Xcode 9 from App Store. Any app that uses MapKit is extremely slow in the iOS11 simulators to the point of it being unusable. This should never have been released.

It could be worse, you may have a Sony TV with an Android OS that keeps crashing 😟

Anyway wellcome to our club.

Still experiencing massive slow downs using mapkit in the simulator basically makes the app untestable. Are Apple working on the issue? Any updates?

Yes, for me the same situation. SpriteKit is very very slow in the simulator.

I filed a radar here, hopefully one of many: https://openradar.appspot.com/radar?id=6138518606708736. Please duplicate to raise attention for getting this into Xcode 9.0.1.

Same issue. This release is a joke. wow. OpenGL apps on the simulator are unusably slow.

iOS 11 and its latest dev tools starting to feel like a massive downgrade across the board.

Just wanted to reiterate here what has already been said numerous times.

This is NOT working still in the released Xcode 9 running on the iOS 11 simulator. It's still soooooooooo slow. To the point of being unusable.

Apple, please... pretty please... fix this asap. Thank you!

Well said. But in truth they are probably working on wonderfull new hardware thet we dont need. To be released next week even before the latest stuff is out.

Same for me guys. Yesterday i downloaded Xcode 9 and the simulator is unusable, so slow!!!

I am experiencing this issue as well. I'm developing an app using MapKit and all was well using XCode 8 but after switching to Xcode 9 and using the Xcode 9 simulator (iOS 11), my app has slown down to a crawl. I am using the release build of Xcode 9 (9A235). The Apple Maps app also runs very poorly on the Xcode 9 simulator.

I am using a Macbook Pro 13'' (Early 2014) (MacbookPro11,1) with 16GB of RAM and a 3Ghz Intel Core i7. I am running macOS Sierra 10.12.6.

Installed Xcode v9.0 (9A235) yesterday via standard AppStore process and simulator is not usable with SpriteKit - sim runs at 1fps.

Same issue with final Xcode 9 release with map kit on Ios11. It is not usable.

Agreed...Xcode 9 simulator is unusable with my latest development project which was fine in the previous Xcode 8 simulator.

Agreed I do have a mac mini and I was using the iphone 7 plus emulator which may not be ideal but at least it worked before.

Come on Apple. you claim the editor is blazingly fast now, so why not make the simulator blazingly fast too.

Apple, please fix this. Xcode is now unusable for me and I have several projects with time limits. I'm running a two month old SSD very fast imac and it is freezing and hung up with the spinning wheel. Please fix.

I am not running mapkit. I am simple referring to just using xcode to edit my code. It hangs up and generally runs very slow. Please help.

Thank you.
