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.
var protectionSpace: NSURLProtectionSpace = NSURLProtectionSpace(
host: host,
port: port,
`protocol`: prot, // Compliant
realm: nil,
authenticationMethod: authenticationMethod
);
