Preinitialised NSArray indicates count is zero?

I am trying to debug an issue, whereby the NSArray I have created shows that it has zero elements.

NSArray *libPaths = [NSArray arrayWithObjects:
            [[NSBundle mainBundle] pathForResource:@"libcustomx.2" ofType:@"dylib"],
            INSTALL_PATH,
            [@"~/Library/Application Support/MyApp/libcustomx.2.dylib" stringByExpandingTildeInPath],
            @"/usr/lib/libcustomx.2.dylib",
            nil];

NSUInteger count = libPaths.count

This is Objective-C code from a project that was originally designed to build on MacOS X 10.6 and I am now trying to get it to build on MacOS X 10.11, using Xcode 7.2.1. Not being very experienced with Objective-C, I am not sure what could be causing a new array to be zero length at this point?

If there is no file in the app bundle named libcustomx.2.dylib then the first value will be nil and the array will be empty.
