A couple of days ago, I was having the oddest issues fetching a SwiftPM package. The package resolution/version solving failed. I still don’t know why this was happening as my package was tagged as “0.1.0” at the time, as confirmed over at Github.

In any case, I found that removing the tag locally and remotely and retagging and re-pushing my tags resolved the issue. The package resolved correctly afterwards.

While I was at this, I decided to update my .gitconfig to add tagging aliases. Here’s what I came up with. They work but they’re not pretty and I’m sure there are better ways to approach this:

####
# Tagging
retag = "!f(){ name=`git tag | tail -1`; \
	git tag -d \"$name\"; echo "Retagged $name"; \
	remote=`git remote -v`; \
	if [ \"$remote\" != \"\" ]; \
	then git push origin --delete \"$name\"; fi; \
	git tag \"$name\"; \
	if [ \"$remote\" != \"\" ]; \
	then git push --tags; \
	else echo "No remote"; fi; };f"
untag = "!f(){ name=`git tag | tail -1`; git tag -d \"$name\"; \
	remote=`git remote -v`; \
	if [ \"$remote\" != \"\" ]; \
	then git push origin --delete \"$name\"; \
	else echo "No remote"; fi; };f"
tagit = "!f(){ git tag \"$@\"; echo "Tagged $name";\
	remote=`git remote -v`; \
	if [ \"$remote\" != \"\" ]; \
	then git push --tags; \
	else echo "No remote"; fi; };f"

retag, which solved my issue, grabs the name of the current tag, removes it, and retags locally and remotely. untag removes the tag and tagit adds a new tag to the current commit.

Feel free to suggest improvements.

p.s. If you’re looking for it, I took down the time machine rant post at the suggestion of several commenters.
