Regression: error : strip exited with code 139
Steps to Reproduce
- Create a new .NET MAUI App (net8 rc2)
- Add package Esri.ArcGISRuntime v200.2.0
<PackageReference Include="Esri.ArcGISRuntime" Version="200.2.0" /> - Build and deploy to a physical device with XCode 15 installed (This didn't happen with xcode 14)
- Observe build error:
1>C:\Program Files\dotnet\packs\Microsoft.iOS.Sdk\16.4.8968-net8-rc2\tools\msbuild\iOS\Xamarin.Shared.targets(2750,3): error : strip exited with code 139
Note that if you skip step 2, there is no issue. Something about this library causes the stripper to crash.
Workaround
Add
<PropertyGroup >
<MtouchNoSymbolStrip Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'ios'">True</MtouchNoSymbolStrip>
</PropertyGroup>
This is quite a showstopper for us, as this prevents any of our users from using our nuget packages. We are fairly certain the issue is connected to the XCode 15 upgrade.
Expected Behavior
App builds and deploys.
Actual Behavior
Crash in the stripper
Environment
VS Preview 17.8 p3+remote macos host, or just .NET 8 RC2 commandline on macos with XCode. We have reproduced on multiple machines, Windows and Mac.

Example Project (If Possible)
Repro project. Just try and deploy to an iPhone device: MauiArcGISApp1.zip
I can reproduce the problem, and it seems to be a buffer overrun in the strip command. I'm still investigating to figure out if this is something we can work around somehow.
Thanks for spotting this @dotMorten - we are in the middle of updating an app with Runtime 200 and this was driving me nuts
FYI unchecking "Strip native debugging symbols" in the Project Properties accomplishes the same thing and everything seems to work as expected.
FYI unchecking "Strip native debugging symbols" in the Project Properties accomplishes the same thing
Yup that's the same as setting MtouchNoSymbolStrip (but the designer always does it bad with weird conditions so I like doing it in the project directly).
Just note that this is not a workaround you really want - this should be considered a temporary fix to unblock our work, until this issue has been addressed.
A better workaround is probably to move back to xcode 14 for now.
Just posting the comments from Discord triage here (thanks @rolfbjarne):

With the latest RC2.1 workload update that shipped yesterday, it appears that Xcode 15 is now required, so we no longer can work around this issue. This makes it a complete showstopper today, rather than in May when XCode 15 will be required by the app store.
@dotMorten I know it's not ideal but can you try Xcode 15.1 Beta 2 to see if it is solved there? We do need some validation.
I submitted a ticket using Apple's feedback assistant (FB13327641), let's see what they say.
If I have time, I'll try to see if there's a way to work around it (won't be this week unfortunately).
I think I figured out the problem with strip, and created a pull request: https://github.com/apple-oss-distributions/cctools/pull/2
@dotMorten can you try adding this to your csproj to see if it fixes the problem?
<PropertyGroup>
<_ExportSymbolsExplicitly>false</_ExportSymbolsExplicitly>
</PropertyGroup>
@rolfbjarne That does appear to workaround it as well. What does this do?
For every P/Invoke, we tell the native linker that it can't remove the symbol in question.
We used to do this by passing -usymbol for each symbol to the native linker, but in .NET 8 we switched to creating a file with all the symbols, and passing the file to the native linker with -exported_symbols_list [file].
Setting _ExportSymbolsExplicitly=false switches back to the old behavior, passing symbols with -usymbol.
Adding
<PropertyGroup> <_ExportSymbolsExplicitly>false</_ExportSymbolsExplicitly> </PropertyGroup>
fixes the issue on iOS, but now I am unable to load resources (Images, Fonts, ...) for Android so best to use a conditional:
<PropertyGroup Condition="'$(TargetFramework)' == 'net8.0-ios'">
Not sure why, but today with .NET 8 RTM + XCode 15.0.1 I'm not seeing this issue. Can anyone else confirm this?
I can't reproduce either.
Note that this doesn't mean all is good: the bug is a memory corruption inside strip, which means we get random behavior, and today that random behavior might be "works as expected."
This seems to have cropped up again in Xcode 16.0 :/
If anyone runs into this, please file a feedback ticket with Apple.
Feel free to reference the pull request with the fix: https://github.com/apple-oss-distributions/cctools/pull/2, and also the existing feedback ticket I raised (FB13327641).
As a workaround, reverting to the 8.0.402 workload fixed the iOS build issue, even with Xcode 16 installed.
Which makes me wonder if this is even an issue with Xcode 16.

Confirmed working on xcode 16 with dotnet workload install maui-ios --version 8.0.402
adding <MtouchNoSymbolStrip>true</MtouchNoSymbolStrip> to my PropertyGroup worked, but causes no breakpoints to work or debug console writing to work. At least. I can run the application for a start.
@corne-ac definitely just a workaround. You don't want to ship apps built with that switch
I've submitted a DTS with Apple for this issue, let's see what they say.

Confirmed working on xcode 16 with

Thanks for the assistance.
Changing workload allows release build to be created and tested on device... thank you. Issue now that I can't run on iOS Simulator with Xcode 16, so I switched back to Xcode 15 which compiles and runs, only to crash on launch with an issue in CommunityToolkit.Maui (9.1). Rolling that back to 9.0.3 allows me to continue development.
So currently using workload 8.0.402, CommunityToolkit.Maui 9.0.3 and Xcode 15 to allow local development and deployment to device.

Also confirmed this has fixed our pipeline, thanks for the heads up. (Subscribing for final solution)
Kudos to @rolfbjarne for submitting an actual fix to Apple.
