1 month ago This happens due to a bug, which we've already fixed, but unfortunately it's not released yet.
In the meantime, you can add this to your binding project file:
<PropertyGroup>
<NoBindingEmbedding>false</NoBindingEmbedding>
</PropertyGroup>However, I noticed that you're using a static library, and that will eventually run into other problems: it doesn't work in the iOS arm64 simulator (because a static library can only contain a single slice of code for each architecture, and the "arm64" slice in the static library is already used up by the device version of "arm64").
The fix is to create an .xcframework bundleinstead of a .a file, and reference that in the project file instead. There are plenty of tutorials online for how to create .xcframeworks, but here's Apple's documentation as a starting point: https://developer.apple.com/documentation/xcode/creating-a-multi-platform-binary-framework-bundle

Description
Hi, I am trying to create a wrapper for a private iOS library. I have the file with the '.a' extension and its headers. This library was working normally, but when I bind this library to .NET MAUI, the build succeeds. However, when using it in a .NET MAUI project, it returns the following error: 'Could not create a native instance of the type 'LibTest.EmbeddedSdk': the native class hasn't been loaded. It is possible to ignore this condition by setting ObjCRuntime.Class.ThrowOnInitFailure to false.' I have already tried with the ObjCRuntime.Class.ThrowOnInitFailure = false option, but when executing the methods, it always returns with a default value. Could you help me with this?
Steps to Reproduce
Expected Behavior
When executing the method: 'value.Init(data)' it should return an int value different from 0 in the MainPage.xaml.cs
Actual Behavior
Return an int value different from 0 and not the erro the type 'LibTest.EmbeddedSdk'
