Definitely run clang-format on this via git cl format as recommended. This will
help with things like the 80-column limit and colon alignment. A couple of other
style nits that I see:

There are two blank lines in a row here, that’s uncommon. Keep it to one.

There also are two blank lines at the end of this file, there shouldn’t be any.

You should be consistent with the way that your files are named. I see
DownloadDelegate starting with a capital D, but I also see systemInfo with a
lowercase s. Starting everything with a capital letter is a more Objective-C way
to go, but the Google/Chrome style is to use all lowercase with underscores,
like download_delegate and system_info. Since this is an isolated Objective-C
project, it’s fine to go with the Objective-C convention, like DownloadDelegate.

These are .m files, which is Objective-C with no C++. We may want to use C++ in
some or all of them, which would be a change to .mm. We can do this as needed,
I’m just mentioning it so that you’re aware.
