Many libraries and frameworks that are being used by most of the IOS services such as ImageIO or libobjc.A.dylib seem to be hidden to me.

Using GDB/IDA I can see that these libraries are successfully imported, but I can't see/access these libraries directly.

For example, libobjc.A.dylib should be located under /usr/lib/, but even with ls -la I cannot see it nor access it.

Anyhow know why this is (filesystem feature?) and how to disable/bypass it?
