Framework entry point in Swift

I just started playing with frameworks in xcode trying to create my own module. When making an iOS app its relatively straightforward where the entry point is ( AppDelegate )

However the framework I've created has nothing like a "main.swift" or similar method.

Do i have to create/specify the entry point on my own? Thanks

EDIT: The reason i'd like the framework to be runnable is so that i can actually print some output while I'm making it to make sure everything works properly.

An answer I got from @deanWombourne points out that if anyone wants to only use the framework project for development as is and develop the framework without integrating it in an app for execution, they can just use the tests provided by the framework for an entry point.

For someone that might be new, all you need to is include unit tests to your project, press on the play button which you normally press on for running and select the wrench icon that writes "test" next to it to run the tests.

(My TL;DR is at the bottom.)

As already stated, there is no entry point like you are thinking. Instead, you should do this:

In your Framework target (I'll assume the framework is named MyFramework):

Add files, classes, properties, subclassed controls, etc. and mark things as public, private, internal, and fileprivate. (See the access level section in the Apple documentation.)

For instance:

public class MyClass1 {
    public var property1 = ""
    private var property2 = ""
    public func myFunc() -> String {
        print("Hello World!")
    }
}
private class MyClass2 {
    var property1 = ""
    var property2 = ""
    func myFunc() -> String {
        return "Hello World!"
    }
}

In your app target (again, assuming your framework is named myFramework):

include MyFramework

class ViewController: UIViewController {
    func tryThis() {
        let myClass1 = myClass1()
        print(myClass1.myFunc())  // prints "Hello World!"
        // the line below will generate a build error 
        // as myClass2 is marks private
        let myClass2 = myClass2()
    }
}

TL;DR

Learn your Access Levels, add code into your Framework target, and import the framework into your app.

A framework doesn't have a traditional entry point like this - it won't ever be run by itself, so it doesn't need one.

To use your framework you would create an app which linked with your framework - the entry point for the app would then call methods from inside your framework.
