Courses Plus Student 11,819 PointsHow to make it work in XCode 9.1 with Swift 4
When attempting to addTarget to our first choice button there's an error that pops up around the # selector
'#selector' refers to a method that is not exposed to Objective-C
To fix this we need to add @objc in front of our function declarations.
e.g. @objc func loadFirstChoice() { ....
Can I ask what this is and why it works? I have read that @objc was implicitly assigned until swift 4. Why and what how does it affect us?
