=== Noncompliant code example

[source,swift]
----
public class Foo {
    public func listUsers() -> [User] {
        var users:[User]
        let location = "/home/mylogin/Dev/users.txt"     // Non-Compliant
        let fileContent = NSString(contentsOfFile: location, encoding: NSUTF8StringEncoding, error: nil)
        users = parse(fileContent!)
        return users
    }
}
----

=== Compliant solution

[source,swift]
----
public class Foo {
    // Configuration is a class that returns customizable properties: it can be mocked to be injected during tests. 
    private var config:Configuration
    public init(myConfig:Configuration) {
        config = myConfig
    }
    public func listUsers() -> [User] {
        var users:[User]
        // Find here the way to get the correct folder, in this case using the Configuration object
        let location = config.getProperty("myApplication.listingFile")
        // and use this parameter instead of the hard coded path
        let fileContent = NSString(contentsOfFile: location, encoding: NSUTF8StringEncoding, error: nil)
        users = parse(fileContent!)
        return users
    }
}
