If you've got something like this:

file was built for arm64 which is not the architecture being linked (x86_64):

Than this gist is for you.

Let's say you have already developed the framework itself and just want to build the binary
and distribute it through the Cocoapods.

1. Make sure your framework "Deployment Target" is equal to all the dependencies from your podspec file.

Basically just type the following in a shell:

irb> require "spaceship"
irb> Spaceship::Tunes.login("iTunesConnect_username", "iTunesConnect_password")

/*
A closure is said to escape a function when the closure is passed as an argument to the function,
but is called after the function returns. When you declare a function that takes a closure as one of its parameters,
you can write @escaping before the parameter’s type to indicate that the closure is allowed to escape.

One way that a closure can escape is by being stored in a variable that is defined outside the function. 
As an example, many functions that start an asynchronous operation take a closure argument as a completion handler.
The function returns after it starts the operation, but the closure isn’t called until the operation is completed — the closure
needs to escape, to be called later. For example:
