os_signposter Cannot convert value of type 'String' to expected argument type > 'StaticString'

Question

We went with the same issue in os_log Using os_log to log function arguments, or other dynamic data so here we go again:

let intervalId = "GetCategoriesUseCase"
let state = signposter.beginInterval(intervalId, id: signpostID)
signposter.endInterval(intervalId, state)

yields

Cannot convert value of type 'String' to expected argument type 'StaticString'

how I am supposed to provide two matching names short of copypasting the string???

Answer 1

StaticString conforms to ExpressibleByStringLiteral so you can change the declaration to

let intervalId: StaticString = "GetCategoriesUseCase"
