My app file size doubles that of what the console says it should...

When I archive my app in xcode, the app file came out EXACTLY 2x that of the original amount. The original one said it was 6.1 mb (in editor log) when built. Then when archived in xcode it doubled to 12.2

Why is this? How can I stop it?

The reason the size is doubled is because I use both armv6 and armv7 architectures, making it have two copies of the same build.
