iOS: String who cannot be nil. How can I do?

Question

Fatal error: unexpectedly found nil while unwrapping an Optional value
I checked that ticket that didn't help me:

  "CODE_SUPLEMENT7": form.csupplement7! != nil ? form.csupplement7! : "",

I try to avoid that mistake, but it says "Comparing non-optional value of type String to nil always return true."

How to find the good type String with the capability to accept the String ? (because my code is all based on it...)

Thanks in advance.

change `form.csupplement7! != nil ? form.csupplement7! : ""` to `form.csupplement7 ?? ""`. You should google about the `??` nil coalescing operator — Leo Dabus, Nov 08 '17 at 18:13

Your problem is your use of ! just before the !=.

It should be:

form.csupplement7 != nil ? form.csupplement7! : ""

But even better is to use ??:

form.csupplement7 ?? ""
