## Component Libraries
In order to keep Alamofire focused specifically on core networking implementations, additional component libraries have been created by the [Alamofire Software Foundation](https://github.com/Alamofire/Foundation) to bring additional functionality to the Alamofire ecosystem.
- [AlamofireImage](https://github.com/Alamofire/AlamofireImage) - An image library including image response serializers, `UIImage` and `UIImageView` extensions, custom image filters, an auto-purging in-memory cache and a priority-based image downloading system.
- [AlamofireNetworkActivityIndicator](https://github.com/Alamofire/AlamofireNetworkActivityIndicator) - Controls the visibility of the network activity indicator on iOS using Alamofire. It contains configurable delay timers to help mitigate flicker and can support `URLSession` instances not managed by Alamofire.
## Requirements
- iOS 8.0+ / macOS 10.10+ / tvOS 9.0+ / watchOS 2.0+

## Installation
### CocoaPods
[CocoaPods](https://cocoapods.org) is a dependency manager for Cocoa projects. You can install it with the following command:
```bash
$ gem install cocoapods
```
> CocoaPods 1.1+ is required to build Alamofire 4.0+.
To integrate Alamofire into your Xcode project using CocoaPods, specify it in your `Podfile`:
```ruby
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '10.0'
use_frameworks!
target '<Your Target Name>' do
pod 'Alamofire', '~> 4.7'
end
```
Then, run the following command:
```bash
$ pod install
```
### Carthage
[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.
You can install Carthage with [Homebrew](https://brew.sh/) using the following command:
```bash
$ brew update
$ brew install carthage
```
To integrate Alamofire into your Xcode project using Carthage, specify it in your `Cartfile`:
```ogdl
github "Alamofire/Alamofire" ~> 4.7
```
Run `carthage update` to build the framework and drag the built `Alamofire.framework` into your Xcode project.
### Swift Package Manager
The [Swift Package Manager](https://swift.org/package-manager/) is a tool for automating the distribution of Swift code and is integrated into the `swift` compiler. It is in early development, but Alamofire does support its use on supported platforms.
Once you have your Swift package set up, adding Alamofire as a dependency is as easy as adding it to the `dependencies` value of your `Package.swift`.
#### Swift 3
```swift
dependencies: [
.Package(url: "https://github.com/Alamofire/Alamofire.git", majorVersion: 4)
]
```
#### Swift 4
```swift
dependencies: [
.package(url: "https://github.com/Alamofire/Alamofire.git", from: "4.0.0")
]
```
### Manually
If you prefer not to use any of the aforementioned dependency managers, you can integrate Alamofire into your project manually.
#### Embedded Framework
- Open up Terminal, `cd` into your top-level project directory, and run the following command "if" your project is not initialized as a git repository:
```bash
$ git init
```
- Add Alamofire as a git [submodule](https://git-scm.com/docs/git-submodule) by running the following command:
```bash
$ git submodule add https://github.com/Alamofire/Alamofire.git
```
- Open the new `Alamofire` folder, and drag the `Alamofire.xcodeproj` into the Project Navigator of your application's Xcode project.
> It should appear nested underneath your application's blue project icon. Whether it is above or below all the other Xcode groups does not matter.
- Select the `Alamofire.xcodeproj` in the Project Navigator and verify the deployment target matches that of your application target.
- Next, select your application project in the Project Navigator (blue project icon) to navigate to the target configuration window and select the application target under the "Targets" heading in the sidebar.
- In the tab bar at the top of that window, open the "General" panel.
- Click on the `+` button under the "Embedded Binaries" section.
- You will see two different `Alamofire.xcodeproj` folders each with two different versions of the `Alamofire.framework` nested inside a `Products` folder.
> It does not matter which `Products` folder you choose from, but it does matter whether you choose the top or bottom `Alamofire.framework`.
- Select the top `Alamofire.framework` for iOS and the bottom one for OS X.
> You can verify which one you selected by inspecting the build log for your project. The build target for `Alamofire` will be listed as either `Alamofire iOS`, `Alamofire macOS`, `Alamofire tvOS` or `Alamofire watchOS`.
- And that's it!
> The `Alamofire.framework` is automagically added as a target dependency, linked framework and embedded framework in a copy files build phase which is all you need to build on the simulator and a device.
## Open Radars
The following radars have some effect on the current implementation of Alamofire.
- [`rdar://21349340`](http://www.openradar.me/radar?id=5517037090635776) - Compiler throwing warning due to toll-free bridging issue in test case
- `rdar://26870455` - Background URL Session Configurations do not work in the simulator
- `rdar://26849668` - Some URLProtocol APIs do not properly handle `URLRequest`
- [`rdar://36082113`](http://openradar.appspot.com/radar?id=4942308441063424) - `URLSessionTaskMetrics` failing to link on watchOS 3.0+
## Resolved Radars
The following radars have been resolved over time after being filed against the Alamofire project.
- [`rdar://26761490`](http://www.openradar.me/radar?id=5010235949318144) - Swift string interpolation causing memory leak with common usage (Resolved on 9/1/17 in Xcode 9 beta 6).
## FAQ
### What's the origin of the name Alamofire?
Alamofire is named after the [Alamo Fire flower](https://aggie-horticulture.tamu.edu/wildseed/alamofire.html), a hybrid variant of the Bluebonnet, the official state flower of Texas.
### What logic belongs in a Router vs. a Request Adapter?
Simple, static data such as paths, parameters and common headers belong in the `Router`. Dynamic data such as an `Authorization` header whose value can changed based on an authentication system belongs in a `RequestAdapter`.
The reason the dynamic data MUST be placed into the `RequestAdapter` is to support retry operations. When a `Request` is retried, the original request is not rebuilt meaning the `Router` will not be called again. The `RequestAdapter` is called again allowing the dynamic data to be updated on the original request before retrying the `Request`.
## Credits
Alamofire is owned and maintained by the [Alamofire Software Foundation](http://alamofire.org). You can follow them on Twitter at [@AlamofireSF](https://twitter.com/AlamofireSF) for project updates and releases.
### Security Disclosure
If you believe you have identified a security vulnerability with Alamofire, you should report it as soon as possible via email to security@alamofire.org. Please do not post it to a public issue tracker.
## Donations
The [ASF](https://github.com/Alamofire/Foundation#members) is looking to raise money to officially stay registered as a federal non-profit organization.
Registering will allow us members to gain some legal protections and also allow us to put donations to use, tax free.
Donating to the ASF will enable us to:
- Pay our yearly legal fees to keep the non-profit in good status
- Pay for our mail servers to help us stay on top of all questions and security issues
- Potentially fund test servers to make it easier for us to test the edge cases
- Potentially fund developers to work on one of our projects full-time
The community adoption of the ASF libraries has been amazing.
We are greatly humbled by your enthusiasm around the projects, and want to continue to do everything we can to move the needle forward.
With your continued support, the ASF will be able to improve its reach and also provide better legal safety for the core members.
If you use any of our libraries for work, see if your employers would be interested in donating.
Any amount you can donate today to help us reach our goal would be greatly appreciated.

# Google Toolbox for Mac - Session Fetcher #
**Project site** <https://github.com/google/gtm-session-fetcher><br>
**Discussion group** <http://groups.google.com/group/google-toolbox-for-mac>
[![Build Status](https://travis-ci.org/google/gtm-session-fetcher.svg?branch=master)](https://travis-ci.org/google/gtm-session-fetcher)
`GTMSessionFetcher` makes it easy for Cocoa applications to perform http
operations. The fetcher is implemented as a wrapper on `NSURLSession`, so its
behavior is asynchronous and uses operating-system settings on iOS and Mac OS X.
Features include:
- Simple to build; only one source/header file pair is required
- Simple to use: takes just two lines of code to fetch a request
- Supports upload and download sessions
- Flexible cookie storage
- Automatic retry on errors, with exponential backoff
- Support for generating multipart MIME upload streams
- Easy, convenient logging of http requests and responses
- Supports plug-in authentication such as with GTMAppAuth
- Easily testable; self-mocking
- Automatic rate limiting when created by the `GTMSessionFetcherService` factory class
- Fully independent of other projects
