Hello Swift Community,

The review for [SE-0285: Ease the transition to concise magic file strings](https://github.com/apple/swift-evolution/blob/master/proposals/0285-ease-pound-file-transition.md) ran from June 6th through June 16th, 2020. You can find the review thread [here](https://forums.swift.org/t/se-0285-ease-the-transition-to-concise-magic-file-strings/38234).

The feedback was generally positive, and to address the concern around which variants of #file library authors should use the proposal was modified to include [Swift API Design Guidelines amendment](https://github.com/apple/swift-evolution/blob/master/proposals/0285-ease-pound-file-transition.md#swift-api-design-guidelines-amendment) encouraging library authors to prefer `#fileID` over alternatives.

Accordingly, SE-0285 is **accepted**.

Thank you to everyone who participated in the review!

Tom Doron,  
Review Manager

I note that this accepted and implemented proposal states the following...

> Standard library assertion functions like `assert` , `precondition` , and `fatalError` will switch from `#file` to `#fileID` . When a filename is included in a compiler-generated trap, such as a force unwrap, it will also emit a literal equivalent to using `#fileID` .

However in Swift 5.3 I still see assert and friends using #file? Was this aspect of the proposal deferred or forgotten? ...or am I missing it on my end?

This is complicating our attempt to move over to use #fileID in some of our code.
