iOS Intermediate Swift Object Initialization Required Initializers

how do I get Xcode to help me for required initialiser's?

How do I setup Xcode so that it will report and error in the IDE when I am missing a required initializer?

At the moment Xcode does through an error and does report it as follows, but doesn't provide a fix in the IDE. ie. the red button with a fix attached?

Any help would be appreciated.

Playground execution failed: error: Initialization.xcplaygroundpage:202:1: error: 'required' initializer 'init(coder:)' must be provided by subclass of 'UIViewController' }

Xcode can indeed help you with this, here's two ways of applying Xcode auto fixes :

  1. Tap on the red error indicator that marks the error in the line number column. If Xcode can provide a quick fix, it will suggest it here. Tap on the fix as well and it will insert/change the code correspondingly.

  2. Use shortcuts to apply auto fixes

Ctrl + Cmd + f // fixes all errors in scope
Ctrl + Cmd + ' // fixes next error
Ctrl + Cmd + " // fixes prev error

Hope that helps :)
