Issues with arc flags

Latest nighty (of_20250303)

Trying to compile ofxSyphon/of_head example results in flags errors.

In Build Settings, -fno-obj-arc is apearing multiple times (and i suspect active for all files in the project)

I suspect this was introduced in 8294756 with this relevant section.

projectGenerator/commandLine/src/projects/xcodeProject.cpp

Lines 490 to 516 in 1e6bdff

	void xcodeProject::addCompileFlagsForMMFile(const fs::path & srcFile) {
	std::ifstream file(srcFile);
	if (!file.is_open()) return;
	bool requiresNoARC = false;
	// Named regex for detecting ARC-related function calls in Objective-C++
	const std::regex arcFunctionRegex(R"(\b(alloc|dealloc|retain|release|autorelease)\b)");
	for (std::string line; std::getline(file, line); ) {
	if (std::regex_search(line, arcFunctionRegex)) {
	requiresNoARC = true;
	break;
	}
	}
	// Tag file as Objective-C++ in Xcode build settings
	for (auto & c : buildConfigs) {
	addCommand("Add :objects:" + c + ":buildSettings:OTHER_CPLUSPLUSFLAGS: string -x objective-c++");
	if (requiresNoARC) {
	addCommand("Add :objects:" + c + ":buildSettings:OTHER_CPLUSPLUSFLAGS: string -fno-objc-arc");
	}
	}
	}

I currently cannot debug deeper into this. I'll try to build projectGenerator to inspect it.
