Answer 1

Go to /Users/username/forge-workspace/compapp1/.template/generate_dynamic/ios_tasks.py line 294,
change this line:
os.rename(tmp_file, filename)
to this one:
shutil.move(tmp_file, filename)
Package again.

Are you using an external hard-drive? If so, it looks like we've been bitten by a limitation of Python here (http://docs.python.org/library/os.html#os.rename):
The operation may fail on some Unix flavors if src and dst are on different filesystems
In the short term, can you run your forge commands not on your external hard drive? We'll work on a fix for the underlying problem and report back here.

I encountered the same issue compiling iOS packages on Ubuntu. I have an encrypted home directory, which is likely the cause of the cross-filesystem issue.
Luckily I was able to work out an easy fix thanks to #Amir's great response.
From http://docs.python.org/dev/library/tempfile.html#tempfile.mkstemp
If dir is specified, the file will be created in that directory; otherwise, a default directory is used. The default directory is chosen from a platform-dependent list, but the user of the application can control the directory location by setting the TMPDIR, TEMP or TMP environment variables.
I simply moved the temp directory by starting Trigger with the following commands:
export TMPDIR="/home/me/tmp"
python /home/me/source/TriggerToolkit/run_trigger_toolkit.py

This is fixed in the v1.4.34 Trigger.io platform version - see http://docs.trigger.io/en/v1.4/release-notes.html#v1-4-34
