FuncationHook != %hookf ???

[be-huge]

I’m very sorry, I can’t see where the problem is. After bridging, Swift can indeed call the CTCellularDataPlanSetIsEnabled method directly, but when hooking it, the system immediately enters Safe Mode.

logos，perfect：

void CTCellularDataPlanSetIsEnabled(Boolean en);
%hookf(void, CTCellularDataPlanSetIsEnabled, Boolean enabled) {
   %orig(enabled);
}

Orion，safemode：

class CTCellularDataPlanSetIsEnabledHook: FunctionHook {
  static let target = Function.symbol("CTCellularDataPlanSetIsEnabled", image: nil);

  func function(_ ioHIDClient: Bool) {
    orig.function(ioHIDClient);
  }
}

The Orion part of this is working fine in my testing.

Are you using a package like "Legacy arm64e Support"? I believe this is a known issue, that some Swift features don't work using that package.

I have not installed the “Legacy arm64e Support” package. My Xcode version is 14.3. When I use Orion’s FunctionHook to hook CTCellularDataPlanSetIsEnabled, SpringBoard crashes. I’m not sure why this happens, because the examples in your documentation look very similar to what I’m doing.

May you attach a crash log?
You should be able to find this in the iOS Settings app -> Privacy & Security -> Analytics & Improvements -> Analytics Data (and then you can search for SpringBoard)

Unfortunately, it doesn’t produce any crash logs at all. When I specify ARCHS = arm64 arm64e in the Makefile, it crashes, but it does not crash when using %hookf. I think this is likely a Swift compatibility issue. This might be something you should look into, because Swift syntax is concise and clean and I really like using it, but I don’t want to mix Logos and Orion in the same project.
