ViewControllers exclusion
After starting obfuscated project we have a lot of crashes related to ViewController classes (e.g. reference in XIB).
In console log we see symbol which caused the crash. After finding that symbol in "symbols.h" we exclude associated class, as described in section "Undefined symbols" of your README.md.
By repeating this process we manage to get app work properly BUT most of our ViewControllers are now excluded. This means that level of protection is now much lower.
Is there a way to fix problematic symbols without excluding classes?
You can exclude only separate symbols with -i <symbol> instead of excluding whole classes with -F <class>. Does it help?
We are using that as well.
But in ViewController crashes symbol (shown in console) is directly associated to class Name (in symbols.h).
Did you try -X <directory> option? This should replace symbols inside XIB and Storyboard files.
I just rerun obfuscation with -X <directory> and result is same.
App crashed on symbol w7G, which is associated to class name of our ViewController.
Crash log is below:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle </Users/urosmil/Library/Developer/CoreSimulator/Devices/B31C711C-EE12-4FEC-BC32-43DAA7529411/data/Containers/Bundle/Application/60637756-D8EF-4590-BC11-F5E0B2FB73D2/THE_APP_NAME.app> (loaded)' with name 'w7G''

There is macro for this:
#define PUSH_VC(Class) [self.navigationController pushViewController:[[Class alloc] initWithNibName:NSStringFromClass([Class class]) bundle:nil] animated:YES]
And it's used in following way:
PUSH_VC(ClassName)
We are not able to reproduce it. Could you please isolate the issue and attach the project that we can use to replicate it?
