How to fix linker error for System framework not found?

When you debug the app on an iOS simulator or on your physical device, it works without errors, right?

For further investigation, could you share the following information with me?

• What's the Xcode version on your Mac?
• Please open Xcode and go to Xcode->Preferences->Location->Command Line Tools and determine what the value is.
• What the detailed publishing command are you using?
• Did you try to publish the app using VS directly? Are there any errors? See Publish a .NET MAUI iOS app for App Store distribution - .NET MAUI | Microsoft Learn

When I debug with an iOS simulator, I get the same error that I posted above.

Error: Severity Code Description Project File Line Suppression State Details Error (active) clang++ exited with code 1: ld: framework not found System clang: error: linker command failed with exit code 1 (use -v to see invocation) testapp (net8.0-ios) C:\Program Files\dotnet\packs\Microsoft.iOS.Sdk.net8.0_17.5\17.5.8030\targets\Xamarin.Shared.Sdk.targets 1641

When I debug with a physical device, I do not get any errors, and it publishes the app to my iOS device with no problem.

Xcode Version: 15.4

Publishing Command: dotnet publish -f:net8.0-ios -c:Release /p:ServerAddress=XXX. /p:ServerUser=mr.dragon /p:ServerPassword=xxx /p:TcpPort=xxx /p:ArchiveOnBuild=true /p:_DotNetRootRemoteDirectory=/Users/mr.dragon/Library/Caches/Xamarin/XMA/SDKs/dotnet/ -v:detailed

I did try to publish my app directly with VS, but I got a nondescript error that stated, "Failed to create app archive 'testapp'."

When I debug on a physical iOS device, it publishes the app to the device with no errors. When I try to use an iOS simulator, I get the following error, which is the same one at the top of the thread.

Error: Severity Code Description Project File Line Suppression State Details Error (active) clang++ exited with code 1: ld: framework not found System clang: error: linker command failed with exit code 1 (use -v to see invocation) RecipeKing (net8.0-ios) C:\Program Files\dotnet\packs\Microsoft.iOS.Sdk.net8.0_17.5\17.5.8030\targets\Xamarin.Shared.Sdk.targets 1641

What's the iOS version of the simulator? And what's the iOS version of your physical device?

From the command line you provided, there are not provisioning profile and sign identity information, do you create distribution provisioning profile?

Simulator Version: 17.5

Physical Device Version: 17.7

I created a certificate, signing identity, and provisioning profile for Apple Distribution. I added a property group to the end of my csproj file, which references the signing and provisioning profiles it should use when building the app for release. I also attempted to remove the snippet below and tried going into the csproj file editor to turn off automatic provisioning. Instead, I set the signing identity and provisioning profile manually, but no matter which method I use, I encounter the same error that initiated this thread.

csproj snippet:

	<PropertyGroup Condition="$(TargetFramework.Contains('-ios')) and '$(Configuration)' == 'Release'">
	<RuntimeIdentifier>ios-arm64</RuntimeIdentifier>
        <!-- Only needed when you have a need for entitlements -->
	<!-- <CodesignEntitlement>Entitlements.plist</CodesignEntitlement> -->
	<CodesignKey>Apple Distribution: Mr. Dragon (83K95XXRSA)</CodesignKey>
	<CodesignProvision>testappProv</CodesignProvision>
	</PropertyGroup>
