Pretty and smart Xcode archive step logs

In our Xcode build steps we use xcpretty to prettify the output of the raw Xcode build log. The raw logs are stored in a temporary directory, so if you want to inspect a failure in detail, you can find the original output.

While xcpretty produces much more digestible output, it is quite common that you can't tell the exact error from the prettified output, but it's included at the end of the raw Xcode build log. So we updated our Xcode steps to print the last 10 lines of the build log into the standard output if the step failed and the output tool was xcpretty. This does not concern the full log, the file is still available.

The new log looks this pretty. 😉

The end of the raw log looks like this:
