@gdar91 can you please try this scenario with a MAUI app (not Blazor) and see if that works? Thanks!

I think the only way you could test iOS 16.2 is if you're using Xcode 14.2, which was just released and is not supported by the currently shipping iOS SDKs. What version of Xcode are you running?

drasticactions avatar Dec 16 '22 06:12 drasticactions

My Xcode Version 14.2 (14C18)

Shineway02 avatar Dec 16 '22 07:12 Shineway02

I have the same issue, working on every iOS version but not on 16.2, only a blank page is shown :/

Murkrow02 avatar Dec 19 '22 16:12 Murkrow02

Thanks for your feedback, @Shineway02 and @Murkrow02.

Could you please check if the issue reproduces on a MAUI project (NOT Blazor) with a normal webview?

I tried creating a blank MAUI (not blazor) project and added a simple web view. The app is working as expected on iOS 16.2

This instead is what happens on 16.2 and 16.0 (running the same application, simple blank starting project for Blazor MAUI) Screenshot 2022-12-19 alle 19 03 51

Murkrow02 avatar Dec 19 '22 18:12 Murkrow02

I have the same issue. It started when I upgraded macOS to 13.1, Visual Studio for Mac to 17.4.2 and XCode to 14.2

My MAUI Blazor project runs ok on MacCatalyst, but on every iOS 16.2 simulator I only see a blank white screen.

Is there any way I could get it working again?

Jinjinov avatar Dec 19 '22 19:12 Jinjinov

@Jinjinov The current net7.0-ios SDK does not support Xcode 14.2. It would be best if you downgraded back to Xcode 14.1 until it receives support.

This issue could be related to underlying issues within the SDK that needs to be addressed.

drasticactions avatar Dec 20 '22 13:12 drasticactions

@drasticactions do you know of another tracking issue for the SDK issue that you're suspicious of?

mkArtakMSFT avatar Dec 22 '22 17:12 mkArtakMSFT

confirmed that downgrading to 16.1 is working

ktravelet avatar Jan 02 '23 00:01 ktravelet

Also it only affects me on Simulator somehow. Testing on real iPhone works though it sucks because I can no longer use Simulator to take screenshots for the App Store. Will check if downloading lower Simulator image version (without XCode) works.

UPDATE: doesn't work. VS can't see those simulators.

datvm avatar Jan 10 '23 10:01 datvm

Is there an estimation ot ETA of when .NET 7 sdk will work with xCode 14.2?

sjbthfc2 avatar Jan 13 '23 09:01 sjbthfc2

Though shows blank UI on iOS 16.2 emulators, app works fine on actual device iPhone 13, iOS 16.3. Using Xcode 14.2, Maui Blazor "hello world" with Maui 7.0.59, .NET 7.0.2, MS.iOS 16.2.1007

Is the problem in the 16.2 simulators and simply need a fix in Xcode to bump and release an Xcode 14.3 with iOS 16.3 simulators? Fred

fzuill avatar Feb 06 '23 17:02 fzuill

I am pretty sure the latest VS for Mac works only with XCode 14.2 (I don't know about the Windows connection thing, I could never get it to work for me so I just use VS for Mac).

So here's how it was after I updated to the latest VS for Mac:

  • It said I didn't have the Workload necessary and running dotnet workload restore installed maui-ios or ios, I didn't notice which one.
  • I cannot compile anything because I had XCode 14.0 or 14.1. It says something like I need to have XCode 14.2.
  • After upgrading, I could compile and run the app well.
  • However as others said, the Blazor app simply shows a blank screen on iOS Simulator (only Blazor app, MAUI app works well, so I assume it's some problem with the Simulator WebView). Note that it's running fine for real devices.
  • Worse, before I could try using older Simulator version. On last update, VS no longer see simulators under 16.x (? not sure, the latest version of iOS). I can only see Simulators with the latest version.

So what it means:

  • I can only debug on real phone.
  • Apps can still be installed manually on older simulator version by drag-n-dropping the file in bin\Debug folder into the Simulator window. However that means no debug is possible. This is only useful if you need screenshot for the Store.

Hope these problems can be fixed soon.

datvm avatar Feb 07 '23 02:02 datvm

This also makes it impossible to upload apps for review, since the Blazor apps also crashes in the simulator during review. "We were unable to review your app as it crashed on launch."

A fix would be greatly appreciated :-)

hakonn avatar Feb 13 '23 17:02 hakonn

Can confirm with @hakonn , now 16.2 simulator simply shows blank screen, while trying to manually install the app through drag-and-drop to older simulators (16.0) would just crash on startup. We have no problem with review though since it runs fine on real devices. It's still an issue that needs to be fixed I believe.

datvm avatar Feb 13 '23 18:02 datvm

They seriously need to review their Xamarin MAUI compilation pipeline and maybe allocate more brainpower for it. Even if they say the GA is there, you can’t depend on it, because when you actually try to use it in production, lots of issues and blockers pop up.

gdar91 avatar Feb 13 '23 18:02 gdar91

why is microsoft so quiet about this? It is a serious bug and we get no information on the progress. Meanwhile they're bashing the drum for hybrid razor on all plattforms. I'm really frustrated - feels like the bad old Xamarin days.

And 5 seconds after I wrote this, I got it working on the 16.0 simulator ... didn't work a couple of days ago.... I did get a new OSX update just 2 days ago, maybe that fixed something!

Lazzerman42 avatar Feb 16 '23 20:02 Lazzerman42

Can anyone reproduce this on an intel machine, or does it only happen on M1/M2 macs?

rolfbjarne avatar Feb 17 '23 15:02 rolfbjarne

Pretty sure that changed by the recent Visual Studio 2022 for Mac v17.4.5 (VS2022 on Windows has a similar update):

Added support for Xcode 14.2 for Xamarin.iOS and Xamarin.Mac.

~~I haven't tried the update on my Mac yet (someone mentioned Intel vs M1/M2 Macs, I only have a M2 Mac) but last time I tried, my previous comment was still correct.~~

Update: after updating VS for Mac to the latest version, I can manually install the Debug build on Simulator 16.0 and run apps without crashing.

datvm avatar Feb 18 '23 13:02 datvm

I can confirm it's only a M1/M2 bug, working fine on my Intel machine. Still an issue if Apple reviewers use Apple silicon (very likely)

AFAIK reviewers use actual devices, and this issue only happens in the simulator.

Does the problem still occur when using iossimulator-arm64 as the RuntimeIdentifier? i.e. add something like this to the csproj:

<PropertyGroup>
    <RuntimeIdentifier>iossimulator-arm64</RuntimeIdentifier>
</PropertyGroup>

rolfbjarne avatar Feb 20 '23 12:02 rolfbjarne

Can confirm, we have many iOS apps successfully published and passed reviews without any issue (no RuntimeIdentifier needed). I simply set the Profile in Bundle Signing (in project property dialog).

If the RuntimeIdentifier is set to iossimulator-arm64, I get the following error:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

I really hope this issue gets resolved soon. Apple already released Xcode 14.3 beta and MAUI doesn't even support 14.2 correctly, which was released over two months ago.

It seems you're using a third-party native library that doesn't support arm64 in the simulator.

I really hope this issue gets resolved soon. Apple already released Xcode 14.3 beta and MAUI doesn't even support 14.2 correctly, which was released over two months ago.

This is a bit complicated to investigate, because Apple's web view rendering is remoted into a different process, and the problem is that this other process crashes. I wouldn't be surprised if this turns out to be a bug in the iOS simulator, because realistically nothing we do should be able to crash this other rendering process.

We've tested this a bit, and it seems that this is the solution.

At some point we'll change the default to build for iossimulator-arm64 when using an ARM64 Mac, but this won't be until .NET 8 at least (it's a rather major change, and it also means a lot of third-party libraries need to add support for iossimulator-arm64 as well - as evidenced by this previous comment).

In the meantime it's possible to add this yourself to the project file.
