Break when a value changes using the Visual Studio debugger
...
Address: &(this->m_value)
Byte Count: 4 (Because int has 4 bytes)
Now, we can resume the program. The debugger will stop when the value is changed.
You can do the same with inherited classes or compound classes.

private:
A m_a;
};

Easy way to see saved NSUserDefaults?
... I've found this has changed in later versions of XCode. You'll now find it in a directory under the current ios version number instead of User - eg /users/your user name/Library/Application Support/iPhone Simulator/4.3/Applications

...aiezza, I second your opinion. I'm fighting with these bloody loops right now, working completely unexpectedly, and I've no idea what is controlling anything looking at the output. Horrid stuff. Useful, but horrid.

If you get this list from somewhere else and don't know if it is ok or not you could create a utility method and use it like this:
for( Object o : safe( list ) ) {
// do whatever
}
And of course safe would be:
public static List safe( List other ) {
return other =...
+ operator for array in PHP?
...array("username"=>"John Doe");
$default_vars = array("username"=>"Unknown", "email"=>"no-reply@domain.com");
$config = $user_vars + $default_vars;

The $user_vars array will overwrite the values defined in $default_vars.

if #available(iOS 9.0, *) {
// use UIStackView
} else {
// show sad face emoji
}
or...
