Sharpie generates some classes with wrong casing

[Cheesebaron]

Apple platform

iOS

Framework version

net10.0-*

Affected platform version

Sharpie 26.3.0.11

Description

I am exposing some classes like URLResponse in NukeProxy and using the @objc macro.

When binding against the generated headers URLResponse becomes NSURLResponse. However, in .NET iOS it should be NSUrlResponse.

Example output:

// -(int64_t)loadDataWithUrl:(NSURL * _Nonnull)url onCompleted:(void (^ _Nonnull)(NSData * _Nullable, NSURLResponse * _Nullable))onCompleted __attribute__((warn_unused_result("")));
[Export ("loadDataWithUrl:onCompleted:")]
long LoadDataWithUrl (NSUrl url, Action<NSData, NSURLResponse> onCompleted);

Steps to Reproduce

Run sharpie against header or framework that uses URLSession in a swift project ala:

dotnet sharpie bind -o src/ImageCaching.Nuke/ -s iphoneos26.2 -n ImageCaching.Nuke -f Output/NukeProxy.xcframework/ios-arm64/NukeProxy.framework

Did you find any workaround?

No response
