How to solve “String interpolation produces a debug description for an optional value; did you mean to make this explicit?” in Xcode 8.3 beta?

Question

Since beta 8.3, zillions warnings \"String interpolation produces a debug description for an optional value; did you mean to make this explicit?\" appeared in my code.

Answer 1

Two easier ways of dealing with this issue.

Option 1:

The first would be by "force-unwrapping" the value you would like to return using a bang (!)

var someValue: Int? = 5
print(someValue!)

Output:

5

Option 2:

The other way, which could be the better way - is to "safely-unwrap" the value you want returned.

var someValue: Int? = 5

if let newValue = someValue {
    print(newValue)
}

Output:

5

Would recommend to go with option 2.

Tip: Avoid force unwrapping (!) where possible as we are not sure if we will always have the value to be unwrapped.
