Semicolons at the end of lines about swift-style-guide HOT 24 CLOSED

Agree on this. Which leads me to say: "no multiple statements on one line", otherwise we'd need semicolons and we don't want them :)

from swift-style-guide.

A reasonable except to multiple statements on one line would be closures.

True, but those don;t require the usage of a semicolo

from swift-style-guide.

I had this in mind:

{ a, b in a = do something; return something with b and a }

If that is short enough to fit on a single line, then why not. Very hypothetical situation, though.

Would you do this in Objective-C or any other language?

from swift-style-guide.

My opinion is that a single line like that looks very "script-y", like ruby of python, so it might lead me to interpret that using the semantics of a scripting language, instead of the Swift one.

from swift-style-guide.

Apple made a big deal out of no semicolons; mentioning it many times in various sessions. While personally I don't want to drop it, I think it makes sense to do just that - drop it, and not use it (except, of course, where it's needed).

from swift-style-guide.

Swift has the semantics of a scripting language. That is one of its promoted benefits.

Nope.

`
var a = "aaa"

a = 12
`

In js is perfectly valid, in Swift throws a compile time error.
Deja vu @ColinEberhardt :)
Anyway let's stop it here.

from swift-style-guide.

I know you already discussed that guys, but can I only add - no semicolons!

The syntax of Swift is like a scripting language. I didn't say it was like that specific scripting language

Semi colons were never an option. Colin only made this issue as a joke. As a tech editor, I will be rejecting any article/chapter that includes semi colons, so you had best do a grep before submitting

No for loops then. :-(

from swift-style-guide.

Absolutely not :)

from swift-style-guide.

I think no semicolons anywhere.

Even

for (i = 0; i < n; i++)

should be switched to

for i in 0..8

from swift-style-guide.

you can write plenty of for loops without semi colons, mister. If you use a semi colon, you'd better have a damn good reason.

How about...

for var i = 0; i < 100; i += 2 { ... }

You can't write that with a for i in 0..100 loop.

from swift-style-guide.

So you have a reason. When I am editing your code, I'll let that semicolon through. If I see an unnecessary semicolon, I will reject you. Rejected!

And the reason I say to grep is because I find myself typing semicolons out of habit, so I am searching for them to remove them. ;)

All right: No line-ending semicolons. "Classic" for loops are ok; whether we should do compact closures that can fit on a line can be argued elsewhere.
I also notice some of you are using non-standard smileys in the comments here! ;]

from swift-style-guide.

Different issue, but we should promote the newer ranged loops when they make sense. So classic for loops should still be the exception rather than the rule

(re-opened) Sorry to be pedantic, but I think issues should only be closed via pull requests that update the style guide. I'd be happy to add a section on semicolon usage as we appear to be in broad agreement here.

Sorry, I closed it by accident. We like pedantic...it is a style guide, after all ;]
