Semicolons

Anyone know if they're "unnecessary but allowed", or if I'm going to have syntax errors on like 60% of my lines of code?

Just read this in the language guide:

Unlike many other languages, Swift does not require you to write a semicolon (;) after each statement in your code, although you can do so if you wish. Semicolons are required, however, if you want to write multiple separate statements on a single line.

So yes, you can type semicolons if it's more comfortable to you - Swift won't complain.

I'm sure it will eventually be considered bad style though.

Be careful what you say! JavaScript tools and JSHint niggle you for the semicolon, but a lot of Node applications are forgoing semicolons entirely.

A reverse opinion, but a valid point. These scripting languages don't need semicolons as long as the programmer knows WHEN THEY NEED THEM.

If Apple doesn't use semicolons in their documentation neither will most developers.

According to the documentation, you MUST use semicolons when writing separate statements on a single line. Not sure then how it would handle a semicolon on a line with one statement.
