…s enabled for a target This introduces a new `enableTesting` API in SwiftSetting which allows targets to explicitly control whether testability is enabled, as some projects do not want to use the @testable feature. This can also improve debug build performance as significantly fewer symbols will be exported from the binary in the case where @testable is disabled. The default is equivalent to `enableTesting(true, .when(configuration: .debug))`, so there is no behavior change from today without explicitly adopting this new API. The --enable-testable-imports/--disable-testable-imports command line flags now acts as overrides -- if specified, they will override any build settings configured at the target level, and if unspecified, the target-level settings will be respected.

Untested draft. Will write up a proposal soon. |

Thanks! Yeah, really want to get some wide community feedback on this. Pretty much everyone fights with enable testing at some point or other. |
