swizzle method

UTType

conformsToType: to conformsToType_iOS:

- (BOOL)conformsToType_iOS:(UTType *)type {

    if (type == nil) {
        return false;
    }
    return [self conformsToType_iOS:type];
}

How were you able to crash the app - by drag & dropping the html files from Notes or some other way? I'm seeing users having the same crash but myself I can't recreate the crash
