Apple doesn't make x86_64 machines anymore, it would be nice, if we could update this code for Apple Silicon. Thx!

Hi!

Thank you so much for this project! I was previously using mach_override, but since I found rd_route, I have switched!

I noticed that at some point (OS X 10.10 DP5 or DP6), calling the reentry function crashes the application. One quick and dirty workaround I found, was to change the _remap_image() function, changing the existing x86_64 hack:
err = mach_vm_allocate(mach_task_self(), new_location, image_size*3, VM_FLAGS_ANYWHERE); mach_vm_size_t lefover = image_size * 2;
to:
err = mach_vm_allocate(mach_task_self(), new_location, image_size*4, VM_FLAGS_ANYWHERE); mach_vm_size_t lefover = image_size * 3;

That (apparently) fixed, but it looks like apps still crash after some time.
One thing that may or not be related, if I injected myself on Quicktime Player (OSX 10.10 too), app crashes immediately when calling rd_route() (at _patch_memory + 178 (rd_route.c:306)).

Hope this helps!

Thank you,
Nuno

Currently we have it hardcoded and limited to 10 mach-o images: that may be not enough in some cases.

Should be nice to have this library available through the CocoaPods dependency manager.

In obj-c properties are syntactic sugar over setFoo: getFoo methods, but in Swift they are closer to ivars (at least from my knowledge). Is there any way to route them as well?

I guess rd_route is kind of software where should be no errors. So every error here implies a critical bug. That's what asserts were invented for.

Would be nice to be able to hook functions in iOS Simulator (e.g. for testing purpose).
