I built my app in the usual way (xcodebuild clean install and so on) and
proceeded to distribute it. But an odd thing happened. I zipped the app
using Tiger's "Create Archive of..." command, and posted the zip file.
Others, downloading this zip file, complained it wouldn't unzip. And indeed,
I tried it on my own machine: I zipped the app, and couldn't unzip the
result (so it has nothing to do with upload / download, as the problem
happens all right there on my machine).
The unzip process gives a very odd error: "Unable to unarchive
"MemoryStick.zip" into [whatever]: Error 17 - File exists."
If I use OpenUp or StuffIt Expander to open the zip file, everything is
fine; it is just the default unzipper, BOMArchiveHelper, that is choking
(but of course that is what everyone uses so everyone experiences the
problem).
Is there a bug in BOMArchiveHelper? Is this a problem caused by some recent
security update? If so (and this is what I'm leading up to), might there be
something wrong with the way I'm building the app that causes it to be
non-unzippable when zipped? m.
