* Compile with `-strict-concurrency=complete`
Only in Bazel for now, because this is considered an unsafe flag in
SwiftPM which would lead to warnings for downstream consumers of
SwiftLint using SwiftPM.
Some imports of SwiftSyntax need the `@preconcurrency` annotation until
https://github.com/apple/swift-syntax/pull/2322 is available in a
release.
The following SwiftLint libraries have `-strict-concurrency=complete`
applied:
* SwiftLintCoreMacros
* SwiftLintBuiltInRules
* SwiftLintExtraRules
The following SwiftLint libraries don't have the flag applied and need
to be migrated:
* SwiftLintCore
* swiftlint (CLI target)
So really the rules and macros are now being compiled with
`-strict-concurrency=complete`, but the core infrastructure of SwiftLint
is not.
Still, given that Swift 6 will eventually make these warnings errors by
default, it's good to prevent issues from creeping in earlier rather
than later.
* Add CI job to build with strict concurrency
Do so by counting characters. Solves (to some extent) the problem of apparent character counts not matching the UTF-8-based offsets returned by SwiftSyntax.
