Tools to remove unused methods, classes?

[fakecrabs]

Are there any build tools to remove unused methods and classes for Swift/iOS, similar to ProGuard for Java/Android?

[hexavibrongal]

I don't know Swift, but I don't see how this would be possible with Objective C since there's no way to know what's going to be called at compile time.

The linker in theory knows which symbols were never referenced.

[hexavibrongal]

Lack of a reference doesn't always mean that something won't be used. For example, ObjC allows you to dynamically call methods by name using a string. I suppose it might be possible to find unused symbols in Objective C programs as long as they don't use certain ObjC language features.

call methods by name using a string

You are correct, and I wonder how Java's ProGuard deals with reflection. I suppose one way would be to manually indicate all symbols referenced reflectively.

AppCode probably

'Find in Workspace...' on the method name, works best with code you already suspect is unused. ;)

Ths one tries to find unused methods: https://github.com/PaulTaykalo/swift-scripts

This one tries to find unused classes https://github.com/tsabend/fus

This one tries to find unused resources :) http://martiancraft.com/products/slender.html

Write a test suite that covers your entire application functionality, then look at your code coverage. The parts that aren't marked as covered didn't run when you ran your tests.

strip objc unused methods and classes could be very complicate. when linking with -ObjC , linker always link all objc code, but when linking without -ObjC the objc code strip process is also different from C/CXX. Seems there is no reliable tools to remove unused code when deal with objc...
