I'm currently writing an app and I need to display a chart of some kind. I created another TableViewController and used it's cell as Bar Chart items.

The question is:

When I try to present it from the main Controller, it throws the Signal Sigbart. Why?

Everything works just fine , for example, if I comment out the present(ViewController) line, and say something like print(123) it's all good. Anyway, here's the code that's causing the problem

  • can you post the stack trace? – willermo Jan 23 '18 at 18:45
  • isn't it obvious in the error message? Always search for words like **resaon**, **error**, **conflict**. Here it says: **Reason: UICollectionView must be initialized with a non-nil layout parameter**. So please show us how you have initialized your collectionView – mfaani Jan 23 '18 at 18:51
  • My bad. I'm not yet used to the debugger in XCode. I was following a tutorial and he was using this as his main Controller. I apologize for the inconvenience . Could you help me with the init for this ? I have the required one already. I'm still learning :( – Mihai Cadis Jan 23 '18 at 19:05
  • use the `@` to mention users so others would be notified. But as for how to instantiate. Did you see [this answer](https://stackoverflow.com/a/35390967/5175709)? If that doesn't work then update your question with the code you tried... – mfaani Jan 23 '18 at 19:47
