reduce app binary file

[alexkaessner]

The installed app binary size is currently relatively high. Would be nice to reduce it more, to have a even smaller download for all users during the event.

BreakOut 3.0 (5):

Compared to this, the old version (v2.2) is rated by the App Store as 42,7 MB size.

I took a look at the binary file we have. And our binary is that big because of 145 MB of frameworks. Most of the bloated binaries are the standard Swift Libraries. Hopefully they won't be relevant in the Store release because of whole-module optimization. However I'm not sure. But this explains why the download is about 40 MB instead of the 180 you see in the settings.

BTW. I just saw that Sweeft takes up 8 MB. Holy sh*t!

We should look into compiling all the FWs as static libraries. We could dramatically reduce the binary file by getting rid of expensive dynamic libraries. Apparently this should be now available for Swift in Xcode 9
