<br>
I have a proposal I’d like to ask you guys to look at before I try to submit it as a formal proposal on the GitHub repository. Before I write a complete draft with a detailed explanation of everything, I’d like to validate my idea a bit. Would it be beneficial to have a shorthand Optional operator in Swift? Currently, when initializing a variable with a non-optional value, the only way to make it optional is by using an explicit type, like this:<br>
<br>
let myOptionalString: String? = “str”<br>
<br>
This syntax can be cumbersome, especially for types with longer names. Now, there’s a force unwrap operator in Swift that allows you to put an optional value into a variable that’s expecting a non-optional type, like this:<br>
<br>
let myForceUnwrappedValue = SomeInitializer()!<br>
<br>
So, to match, and to make things shorter, do you think there should be an operator that allows developers to achieve the same effect, but without an explicit type? Like this:<br>
<br>
let myOptionalString = “str”?<br>
<br>
Could you guys let me know what you think? Thanks for the help!<br>
