You can't create a variable named "for". Unless you put backticks (``++`++``) around it.
|
|
|
|
|
|
Since that would be the first step down a slippery slope of hopeless confusion, backticks should be removed from identifier names - whether they're keywords or not - and the identifiers renamed as required.

== Noncompliant Code Example
|
|
|
|
----
|
|
var `for` = 1 // Noncompliant
|
|
for (var `in` = 0; `in` < 10 && `for` > 0; `in`++) { // Noncompliant
|
|
// ...
|
|
}
|
|
|
|
var `x` = "hello" // Noncompliant; why would you do this?

== Compliant Solution
|
|
|
|
----
|
|
var i = a
|
|
for (var j=0; j< 10; j++) {
|
|
// ...
|
|
}
|
|
|
|
var x = "hello"

== Exceptions

When Objective-C libraries are used in Swift, backticks may be needed around parameter names which are keywords in Swift but not in Objective C. Therefore this rule ignores backticks around parameter names.
