Package

Sentry

.NET Flavor

.NET

.NET Version

8.0.8

OS

iOS

SDK Version

4.10.2

Self-Hosted Sentry Version

No response

Steps to Reproduce

1. Install Xcode 16 using Xcodes
2. Set Xcode 16 active (sudo xcode-select -s /Applications/Xcode-16.0.0.app/Contents/Developer)
3. Install .NET 8 tools with Xcode 16 support (see here)
4. Create new iOS app (dotnet new ios)
5. Add latest Sentry SDK (v4.10.2) from NuGet
6. dotnet publish

Expected Result

The app builds

Actual Result

Error while building:
/usr/local/share/dotnet/packs/Microsoft.iOS.Sdk.net8.0_18.0/18.0.8287-xcode16/tools/msbuild/iOS/Xamarin.Shared.targets(2848,3): error : strip exited with code 139

This issue has been discussed previously here and a PR was created here (but not accepted yet).

For some reason, I was successful building my app successfully yesterday with the same tooling & Sentry version, but not today. It now consistently fails with every test project if I have the Sentry SDK added to, and it succeeds consistently when I remove it.

@tipa do you have your Sentry version pinned? A 4.11.0 release was made a few hours ago.

This is odd though as both the bug and the solution that you linked to seem to be part of a dotnet workload rather than part of Sentry.

[tipa]

The issue also happens for me with 4.11.0.
I agree that this totally looks like a problem of dotnet or the Apple tooling - I opened this issue because you perhaps could or would want to workaround the issue since since the it can be reproduced so easily and reliably (at least in my dev environment now, with Xcode 16). Perhaps, as more users .NET users update to Xcode 16, more people could be affected. Are you able to reproduce the problem with the steps I provided?

[bitsandfoxes]

There are a couple of new issues regarding Cocoa and Xcode 16 as well so I don't expect this to be the last of our problems.

[jamescrosswell]

I haven't had a chance to try this yet. I'm a bit nervous about installing XCode 16, at least until we can get all the groundwork in for Sentry working smoothly with net9.0... I'm trying to change as few things as possible, at once.

[tipa]

@jamescrosswell You can install XCode side-by-side with Xcode 15 - I explained the steps in my first post

[jamescrosswell]

You like living on the bleeding edge eh @tipa 😜 ?

Thanks for the tip re xcodes.

In this issue it looks like XCode 16 support will come with the net9.0 release in November.

I see in the NSTextList issue that there might be a preview coming in RC2 (~3 weeks away). Once RC2 is available, I'll see if I can reproduce. Even if we can't fix the problem, potentially we can research a workaround.

I'm also seeing this issue is back again with xcode16

Until dotnet/maui supports XCode 16, I think the only practical workaround is to install Xcode 15.4 also/instead.

The latest MAUI workload requires XCode 16

You mean if you target net9.0? We're working on net9.0 support. For MAUI, in particular, it's pretty challenging so it might take a while... hoping to have a pre-release available shortly after Microsoft release net9.0.

We're forced to bump to Xcode 16 in CI now as well: #3635
Microsoft.iOS 18.0.8303 requires Xcode 16.0 or later. See this run

[dotMorten]

No even for net8

[krobotics]

I ran into this issue yesterday while trying to run a pipeline on devops (about the time that 18.0.8303 was released) got an error telling me to use xcode 16. This gave the code 139 error. Removing sentry from my code allowed the build on iOS.
I can still build from Visual Studio but have not figure out how to get the pipeline to use xcode 15.4 and Microsoft.iOS.Sdk 17.5.8030.

Aha - I see a new net8.0 release has been made to support XCode 16 👍🏻

[UsherNet]

Tried to update to latest CommunityToolkit.Maiu with requested updated workload then meant switching to Xcode 16, now facing the same "strip exited with code 139" error, which is preventing new builds from being produced for production. Now at a standstill until we can make sense of what is going on. I've tried different settings but continue to get the error. :(

[angularsen]

A workaround is to downgrade maui-ios workload by specifying the version:

dotnet workload install maui-ios --version 8.0.402

or if you build MAUI for both iOS and Android:

dotnet workload install maui --version 8.0.402

[bitsandfoxes]

Thanks @angularsen for providing a workaround!

We're working on resolving this as soon as possible.

[bitsandfoxes]

Good news is: I cannot reproduce this anymore with the steps provided in the issue description in my local environment.
Bad news is: I don't know what changed. Because there are no changes to the SDK that I'm aware of that could have fixed the issue. Is this just all in the dependencies?

[dotMorten]

I'm finding the issue occurs randomly. I can often build it at few times and sometimes it fails and others it works.
