Hi, thank you for the feedback. Could you let us know what version of MAUI you are using? Is this the first version that is being tested on a physical iPad or did this used to work on a physical iPad in a different version and no longer works? Also, are you able to reproduce this behavior in a project you can share? |
|
I'd also be curious if this happens on a physical iPhone as well or if this is exclusively happening on iPads? |

Hi, thank you for the feedback. I am using MAUI version 8.0.100 with the following workloads: Android: 34.0.113 / 8.0.100 I haven't been able to figure out exactly where the crash is happening since there were no issues during my own tests. Could this discrepancy between the iOS versions (17.5 vs. 18) be the cause of the problem? |

As I mentioned earlier, I haven't tested the app on physical devices yet—only virtual ones. However, I believe the Apple review team likely tested it on iPhones first and then moved to iPads. I'm not entirely certain about this, |
|
When you test on a virtual device, do you do a release build? That would be closest to what they are testing I guess. |
|
i ran into an issue like this once. Try out some different regions on your simulators (try USA and France). The exact issue I had involved float.ToString() and float.Parse(), which has different behavior depending on region unless you specify CultureInfo.InvariantCulture. |
|
I am having the same issue as well testing my app that is developed in .NET MAUI 8 attempting to run in iOS 18. @jfversluis, I deployed my app to a physical device that has iOS 18 and it gets stuck in the splash screen and only shows blank white screen and won't get passed it! |
|
@MohammedBen what specific version of .NET MAUI? That sounds like #23906 which should be fixed in more recent versions. Good suggestion @orecros thanks! |
|
I am targeting .NET 8 for iOS |
|
@MohammedBen looks like that fix is merged for either .NET MAUI 8.0.80 or .NET 9 RC1 so you will want to use those versions to fix that for iOS 18 |
In the last few hours !! |
|
@jfversluis Do you think this is the reason for the error? |
|
|
@Kremed looks like this is cause by your release build settings. MAUI has different default values for Release builds and Debug builds on iOS for performance reasons/ hot restart etc.. some performance optimizations might not be supported by your dependencies, such as AOT compilation. In case you use CLI to build your package: |
I've taken a lot of time, and now we're encountering an issue we don't know how to fix or what is causing it! One more detail, I think all of this happened after I updated the DevExpress components. Could this be the reason? |
|
@Kremed the errors looks like llvm is failing for AlohaKit. Does it work when you use: |
|
No response for 2 weeks, I hope this means you figured it out! |
|
In my case, I had to configure VS to point to XCode 15.4 rather than the latest xocde 16.x. Thank you for your assistance.

Description
Discussion Summary: This may not be an issue but rather a request for help with troubleshooting. Our app,
version 1.3.0 (Bundle ID: com.kremed.swap), crashes on launch during Apple's App Review process on aniPad Air (5th generation) running iOS 18.0. The crash happens immediately after launch, but we have not encountered any issues during testing on all virtual iPad devices on macOS. The app works perfectly in these virtual environments, and we are unable to reproduce the crash locally.I believe this is not a bug in the .NET MAUI SDK, as everything functions smoothly in our local environment. However, we are unsure where exactly the issue lies, and any assistance in identifying the problem would be appreciated.
