1 year ago 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.

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.

1 year ago 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.

1 year ago @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?
rolfbjarne
commented
1 year ago 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.

rolfbjarne
commented
11 months ago 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."

Confirmed working on xcode 16 with
dotnet workload install maui-ios --version 8.0.402
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.

Hi @rolfbjarne, did you have by any chances a patch diff for cctools? I ask because (I guess) we can compile it and install a modded version of strip in /usr/local/bin??
P.S. cctools-1010.6 appear to be 7 month old. Maybe it should work out of the box if is not the latest shipped with Xcode 16? edit: I'm running net9 rc2 and I have a strip error in relese build

FWIW I don't think you can replace /usr/bin/strip (at least not without disabling Apple's System Integrity Protection), but I think that executable only executes the one shipped with Xcode (/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/strip), which you can replace.

Hi and thanks for replying. The command can be placed where you like most, even inside the dotnet directory. What matter is your enviroment variable $PATH which can be manipulated to look first to a custom path so when you invoke strip, the first one will be used:
echo $PATH /usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/local/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/appleinternal/bin:/Library/Apple/usr/bin:/usr/local/share/dotnet:~/.dotnet/tools:/Library/Frameworks/Mono.framework/Versions/Current/Commands
As you can see, by default, /usr/local/bin is already the first path in $PATH, and is not protected by SIP. That unless a full path (e.g. ../usr/bin/strip) is given by the microsoft build tool, which in the case it would ruin the whole thing. Anyway it can than be used from a sh script and or Terminal. Note that dotnet is the last...but can be changed...
I'll let you know if I'll be able to compile your fixes.

4 weeks ago Hi @rolfbjarne I succeded, but to build a fixed "strip" llvm must be installed. Steps I made (if someone is intrested in):
decompress it and rename it just "llvm". After that create /usr/local/opt directory (will require elevated privileges). Copy llvm to /usr/local/opt/. Be aware that you need to include the new toolchain in your bash profile otherwise Xcode will not find it, or edit the cctools source code to include needed headers where it complains.
dowload https://github.com/apple-oss-distributions/cctools/archive/refs/tags/cctools-1010.6.tar.gz and decompress it.
create a directory named "mybin" inside it (cctools-cctools-1010.6/mybin).
patch ../cctools-cctools-1010.6/misc/strip.c as suggested by @rolfbjarne: after line 3857 (after new_ext_strsize += len;) insert:
if ((n_type & N_TYPE) == N_INDR && n_value != 0) {
len = strlen(strings + n_value) + 1;
new_ext_strsize += len;
}compile using terminal:
cd path/to/cctools-cctools-1010.6
then
xcodebuild -scheme strip -configuration Release ARCHS=arm64 ONLY_ACTIVE_ARCH=YES CONFIGURATION_BUILD_DIR=./mybin
Now copy path/to/cctools-cctools-1010.6/mybin/strip to /usr/local/bin/ (you may need to create the bin directory).
It will work now? No because as feared, the dotnet toolchain expect "strip" to be inside /Application/xcode/......./usr/bin/. and the enviroment variable $PATH is totally ignored (why??). To force the use of the new /usr/local/bin/strip you have to edit "Executable" in the following file (be aware that I'm using net9 rc2):
/usr/local/share/dotnet/packs/Microsoft.iOS.Sdk.net9.0_18.0/18.0.9600-net9-rc2/tools/msbuild/iOS/Xamarin.Share.targets
from:
<!-- strip the debug symbols from the executable -->
<SymbolStrip
SessionId="$(BuildSessionId)"
Condition="'$(IsMacEnabled)' == 'true'"
Executable="$(_AppContainerDir)%(_NativeStripItems.Identity)"
Kind="%(_NativeStripItems.Kind)"
MaxDegreeOfParallelism="$(SymbolStripMaxDegreeOfParallelism)"
SymbolFile="%(_NativeStripItems.SymbolFile)"
/>
to:
<!-- strip the debug symbols from the executable -->
<SymbolStrip
SessionId="$(BuildSessionId)"
Condition="'$(IsMacEnabled)' == 'true'"
Executable="/usr/local/bin/strip"
Kind="%(_NativeStripItems.Kind)"
MaxDegreeOfParallelism="$(SymbolStripMaxDegreeOfParallelism)"
SymbolFile="%(_NativeStripItems.SymbolFile)"
/>Finally, I can produce the smallest binary possible in Release mode using net9 + Xcode 16 on macOS 15.0.1 directly on my devices (which is working).
Final considerations: the above is a a proof of concept that we don't have to wait months Apple for a fix, but maybe we can include a precompiled-fixed copy of strip directly in the dotnet toolchain, or let the user using a different binary.

Hi, I want to clarify that I don't want to encourage peoples to modify/ruin their toolchains, my point was only that maybe microsoft guys can build a fixed version and ship it in the net toolchain for maui. Could be right, could be wrong. After that you surely missing some headers as your enviremont variables to include LLVM aren't set at all. You can have anyway a build by edit those files manually, and you can see where it complains by running cctools in Xcode with the strip target selected. They should be:
Open /cctools-cctools-1010.6/libstuff/reloc.c delete line 166 and 167 as you dont have 'CPU_TYPE_RISCV32' defined. You are compiling for arm cpu, so it's safe:
case CPU_TYPE_RISCV32:
return(FALSE);Again, as you don't have the enviroment variable set to include llvm in $PATH nor the include path:
Open /cctools-cctools-1010.6/libstuff/lto.c
edit lto include from:
#include <llvm-c/lto.h>
to
#include "/usr/local/opt/llvm/include/llvm-c/lto.h" // or where ever you have llvm
I guess this should be enough, unless in your system other headers are missing.
EDIT modify strip.c is still needed :)

3 weeks ago @MichelePannacciTerex Thanks so much for your repeated help. I did add LLVM to the path (or included the path the HEADER_SEARCH_PATHS) - but that caused a trillion of other errors (something in the sort of "int64_t not found"). It took me 2 hours until I just manually edited the #imports that weren't found and filled in the exact path on my machine. Also had to adjust an #import in a file somewhere in the llvm folder. But then it finally worked!
And I agree that perhaps this fix should be applied by Microsoft as it's probably rather unlikely that Apple fixes this on their own anytime soon...

Glad it worked, but do not thanks me. Thanks @rolfbjarne for the real fix

3 weeks ago @MichelePannacciTerex I did some tests with the self-compiled strip (and with a project that wouldn't need the workaround). For some reasons, it appears that it results in larger .ipa bundles than the original strip file:
Now I'm lost again... π

Hi, I'm not sure I can help further, mine goes from almost 300 MB to 24 MB. Did you have the Interpreter enabled?

3 weeks ago Tried with a blank dotnet new ios project and only removed TrimMode=full and added PublishAot=true. The old strip generates a 1.1 MB ipa, the self-compiled on a 1.6 MB ipa file. Are you seeing different results? Does it matter on what machine I use the file? I compiled it on a macOS 15 machine but use it on macOS 14

Hi, lastest cctools minimum deployment target is macOS 14.0, but this has nothing to do with anything as otherwise it will just crash. Unfortunately I did not make any comparisons about sizing because I've just updated only one maui project to the net9 toolchain (waiting for the official final release), or to be more precise the ipa is a little bigger than it used to be if compiled against net8; so considering that I updated all the packages, and that iOS SDK is different... I didn't ask myself too many questions (yet) because I just thought it was a lot better than nothing (error code 139). I'm not even sure if Xcode 16 provides a version of cctools that matches the latest commit on their repository, but as it's in a working state it's also strange to me of such difference on the same project (and targeting the same device). I'll leave my compiled binary here if you want to try it, although I don't see how it could be any better. One final consideration is that the fix provides more space for the processed indirect symbols (a bigger size then?), so I'm not completely sure the old strip is better, or at least not in all scenarios your app can jump in. strip.zip

3 weeks ago I did a full macOS reinstall, and now Iβm encountering this issue as well. Whatβs the best workaround available for publication right now? Iβm able to build and test a debug build, but I run into this error when trying to create a release build.

I don't think we should expect them to. I see your pull-request is a year old - did it suddenly fix itself last year, if so what changed?

They prioritize feedback tickets depending on how many duplicates a ticket has, which is why I've asked people who run into this to file feedback tickets with Apple.
The difference is exactly that: how many people are running into the bug (and are hopefully reporting it to Apple).
Please file a feedback ticket with Apple if you run into this issue
See this comment for more information: https://github.com/xamarin/xamarin-macios/issues/19157#issuecomment-2363300980
Steps to Reproduce
<PackageReference Include="Esri.ArcGISRuntime" Version="200.2.0" />Note that if you skip step 2, there is no issue. Something about this library causes the stripper to crash.
Workaround
Add
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.
