                Git config with multiple identities and multiple repositories
              
          
    Setup multiple git identities & git user informations


/!\ Be very carrefull in your setup : any misconfiguration make all the git config to fail silently !
Go trought this guide step by step and it should be fine 😉

Setup multiple git ssh identities for git


Generate your SSH keys as per your git provider documentation.
Add each public SSH keys to your git providers acounts.
In your ~/.ssh/config, set each ssh key for each repository as in this exemple:


## didSet_children_updates.swift
#!/usr/bin/swift

class Node {

    var children: [Node] = []

    var depth: Int = 0 {
        didSet {
            for child in children {
                child.depth = depth + 1

## equivalent_protocol_definition.swift
protocol MyView: UIView { /*…*/ }
protocol MyView where Self: UIView { /*…*/ }

## casting_optional_to_generic_type.swift
func forceCast<U>(_ value: Any?, to type: U.Type) -> U {
 return value as! U
}
let value: Any? = 42
print(forceCast(value, to: Any.self))
// Prints "Optional(42)"
// (Prior to Swift 5, this would print "42".)
print(value as! Any)
// Prints "Optional(42)"

## autoclosure.swift
func foo(_ fn: @autoclosure () -> Int) {}
func bar(_ fn: @autoclosure () -> Int) {
  foo(fn) // Incorrect, `fn` can't be forwarded and has to be called.
  foo(fn()) // OK
}

            operation()
