When exporting an iOS Project will delete source code

[SAGESSE-CN]

Tested versions

• Reproducible in v4.2.1.stable.official [b09f793]

System information

Godot v4.2.1.stable - macOS 13.6.5 - Vulkan (Forward+) - integrated Intel(R) Iris(TM) Plus Graphics 655 - Intel(R) Core(TM) i7-8569U CPU @ 2.80GHz (8 Threads)

Issue description

when exporting an iOS Project to the exists directory parent, it will be remove it directly.

my all code is lost because of this!!!!

expect any warning or confirm or somethink.

Steps to reproduce

1. create a new project, specify directory /xxx/project/mygame
2. create a empty scene
3. export iOS Project, specify export directory /xxx/project/
4. you will lose all source code

Minimal reproduction project (MRP)

• no need this

iOS exporter deletes binary_name + ".xcodeproj" and binary_name specifically, since these are the directories created during export. So if you use mygame as export name, it will delete it. No sure how to fix it (or if it should be fixed), since not deleting it will result in broken export if you export multiple times to the same folder.

We could for example search for a project file in the path, but it'd still be risky, as it could be in any nested folder, unsure how it could be done reliably, alternatively we could reqire that the folder is either empty (or does not exist) or contains some specific data from exporting

This is the relevant code:

godot/platform/ios/export/export_plugin.cpp

Lines 1629 to 1643 in fe01776

	{
	Ref<DirAccess> da = DirAccess::create(DirAccess::ACCESS_FILESYSTEM);
	if (da.is_valid()) {
	String current_dir = da->get_current_dir();
	// remove leftovers from last export so they don't interfere
	// in case some files are no longer needed
	if (da->change_dir(binary_dir + ".xcodeproj") == OK) {
	da->erase_contents_recursive();
	}
	if (da->change_dir(binary_dir) == OK) {
	da->erase_contents_recursive();
	}
	da->change_dir(current_dir);

We could also make the binary dir have some suffix making it unlikely to match your project directory in the case you name the binary the same

We could also enforce the export happening in specific places as well

This code actually is broken and will delete it only if there's no binary_dir + ".xcodeproj":

if (da->change_dir(binary_dir + ".xcodeproj") == OK) {  // enters dest/binary_dir.xcodeproj
	da->erase_contents_recursive(); 
} 
if (da->change_dir(binary_dir) == OK) { // if previous changedir was sucessfull, enters dest/binary_dir.xcodeproj/binary_dir which will not exist
	da->erase_contents_recursive(); 
}
