Not compatible with swift build

[Natanil]

I have a project which use swift as its default build option and i dont want to change it to objective_c , your manual for replacing appdelegate is just for objective_c projects so please add an alternative to support swift build , another problem is when i change the project to objective_c for testing the package i got an error which says 'Socket.IO-Client-Swift', '~> 13.3.0' is not in the repository anymore.
