Packages can now declare executable targets
Available from Swift 5.4
SE-0294 (apple/swift-evolution) adds a new target option for apps using Swift Package manager, allowing us to explicitly declare an executable target.
This is particularly important for folks who want to use SE-0281 (apple/swift-evolution) (using @main to mark your program’s entry point), because it didn’t play nicely with Swift Package Manager – it would always look for a main.swift file.
With this change, we can now remove main.swift and use @main instead.
Note
You must specify // swift-tools-version:5.4 in your Package.swift file in order to get this new functionality.
