+# Firebase APIs for iOS
+
+Simplify your iOS development, grow your user base, and monetize more
+effectively with Firebase services.
+
+Much more information can be found at [https://firebase.google.com](https://firebase.google.com).
+
+## Install a Firebase SDK using CocoaPods
+
+Firebase distributes several iOS specific APIs and SDKs via CocoaPods.
+You can install the CocoaPods tool on OS X by running the following command from
+the terminal. Detailed information is available in the [Getting Started
+guide](https://guides.cocoapods.org/using/getting-started.html#getting-started).
+
+```
+$ sudo gem install cocoapods
+```
+
+## Try out an SDK
+
+You can try any of the SDKs with `pod try`. Run the following command and select
+the SDK you are interested in when prompted:
+
+```
+$ pod try Firebase
+```
+
+Note that some SDKs may require credentials. More information is available in
+the SDK-specific documentation at [https://firebase.google.com/docs/](https://firebase.google.com/docs/).
+
+## Add a Firebase SDK to your iOS app
+
+CocoaPods is used to install and manage dependencies in existing Xcode projects.
+
+1.  Create an Xcode project, and save it to your local machine.
+2.  Create a file named `Podfile` in your project directory. This file defines
+    your project's dependencies, and is commonly referred to as a Podspec.
+3.  Open `Podfile`, and add your dependencies. A simple Podspec is shown here:
+
+    ```
+    platform :ios, '8.0'
+    pod 'Firebase'
+    ```
+
+4.  Save the file.
+
+5.  Open a terminal and `cd` to the directory containing the Podfile.
+
+    ```
+    $ cd <path-to-project>/project/
+    ```
+
+6.  Run the `pod install` command. This will install the SDKs specified in the
+    Podspec, along with any dependencies they may have.
+
+    ```
+    $ pod install
+    ```
+
+7.  Open your app's `.xcworkspace` file to launch Xcode. Use this file for all
+    development on your app.
+
+8.  You can also install other Firebase SDKs by adding the subspecs in the
+    Podfile.
+
+    ```
+    pod 'Firebase/AdMob'
+    pod 'Firebase/Analytics'
+    pod 'Firebase/Auth'
+    pod 'Firebase/Crash'
+    pod 'Firebase/Database'
+    pod 'Firebase/DynamicLinks'
+    pod 'Firebase/Firestore'
+    pod 'Firebase/Functions'
+    pod 'Firebase/Invites'
+    pod 'Firebase/Messaging'
+    pod 'Firebase/MLCommon'
+    pod 'Firebase/MLModelInterpreter'
+    pod 'Firebase/MLVision'
+    pod 'Firebase/MLVisionBarcodeModel'
+    pod 'Firebase/MLVisionFaceModel'
+    pod 'Firebase/MLVisionLabelModel'
+    pod 'Firebase/MLVisionTextModel'
+    pod 'Firebase/Performance'
+    pod 'Firebase/RemoteConfig'
+    pod 'Firebase/Storage'

Pods/FirebaseAuth/Firebase/Auth/CHANGELOG.md

+# v4.6.1
+- Fixes crash which occurred when certain Firebase IDTokens were being parsed (#1076).
+
+# v4.6.0
+- Adds `getIDTokenResultWithCompletion:` and `getIDTokenResultForcingRefresh:completion:` APIs which
+  call back with an AuthTokenResult object. The Auth token result object contains the ID token JWT string and other properties associated with the token including the decoded available payload claims (#1004).
+
+- Adds the `updateCurrentUser:completion:` API which sets the currentUser on the calling Auth instance to the provided user object (#1018).
+
+- Adds client-side validation to prevent setting `handleCodeInApp` to false when performing
+  email-link authentication. If `handleCodeInApp` is set to false an invalid argument exception
+  is thrown (#931).
+
+- Adds support for passing the deep link (which is embedded in the sign-in link sent via email) to the
+  `signInWithEmail:link:completion:` and `isSignInWithEmailLink:` methods during an
+  email/link sign-in flow (#1023).
+
+# v4.5.0
+- Adds new API which provides a way to determine the sign-in methods associated with an
+  email address.
+- Adds new API which allows authentication using only an email link (Passwordless Authentication
+  with email link).
+
+# v4.4.4
+- Addresses CLANG_WARN_OBJC_IMPLICIT_RETAIN_SELF warnings that surface in newer versions of
+  Xcode and CocoaPods.
+- Improves FIRUser documentation with clear message explaining when Firebase Auth attempts to validate
+  users and what happens when an invalidated user is detected (#694) .
+
+# v4.4.3
+- Adds an explicit dependency on CoreGraphics from Firebase Auth.
+
+# v4.4.2
+- Fixes bug where the FIRAuthResult object returned following a Phone Number authentication
+  always contained a nil FIRAdditionalUserInfo object. Now the FIRAdditionalUserInfo object is
+  never nil and its newUser field is populated correctly.
+
+# v4.4.0
+- Adds new APIs which return an AuthDataResult object after successfully creating an
+  Email/Password user, signing in anonymously, signing in with Email/Password and signing
+  in with Custom Token. The AuthDataResult object contains the new user and additional
+  information pertaining to the new user.
+
+# v4.3.2
+- Improves error handling for the phone number sign-in reCAPTCHA flow.
+- Improves error handling for phone number linking flow.
+- Fixes issue where after linking an anonymous user to a phone number the user remained
+  anonymous.
+
+# v4.3.1
+- Internal clean up.
+
+# v4.3.0
+- Provides account creation and last sign-in dates as metadata to the user
+  object.
+- Returns more descriptive errors for some error cases of the phone number
+  sign-in reCAPTCHA flow.
+- Fixes an issue that invalid users were not automatically signed out earlier.
+- Fixes an issue that ID token listeners were not fired in some cases.
+
+# v4.2.1
+- Fixes a threading issue in phone number auth that completion block was not
+  executed on the main thread in some error cases.
+
+# v4.2.0
+- Adds new phone number verification API which makes use of an intelligent reCAPTCHA to verify the application.
+
+# v4.1.1
+- Improves some method documentation in headers.
+
+# v4.1.0
+- Allows the app to handle continue URL natively, e.g., from password reset
+  email.
+- Allows the app to set language code, e.g., for sending password reset email.
+- Fixes an issue that user's phone number did not persist on client.
+- Fixes an issue that recover email action code type was reported as unknown.
+- Improves app start-up time by moving initialization off from the main
+  thread.
+- Better reports missing email error when creating a new password user.
+- Changes console message logging levels to be more consistent with other
+  Firebase products on the iOS platform.
+
+# 2017-05-17 -- v4.0.0
+- Adds Phone Number Authentication.
+- Adds support for generic OAuth2 identity providers.
+- Adds methods that return additional user data from identity providers if
+  available when authenticating users.
+- Improves session management by automatically refreshing tokens if possible
+  and signing out users if the session is detected invalidated, for example,
+  after the user changed password or deleted account from another device.
+- Fixes an issue that reauthentication creates new user account if the user
+  credential is valid but does not match the currently signed in user.
+- Fixes an issue that the "password" provider is not immediately listed on the
+  client side after adding a password to an account.
+- Changes factory methods to return non-null FIRAuth instances or raises an
+  exception, instead of returning nullable instances.
+- Changes auth state change listener to only be triggered when the user changes.
+- Adds a new listener which is triggered whenever the ID token is changed.
+- Switches ERROR_EMAIL_ALREADY_IN_USE to
+  ERROR_ACCOUNT_EXISTS_WITH_DIFFERENT_CREDENTIAL when the email used in the
+  signInWithCredential: call is already in use by another account.
+- Deprecates FIREmailPasswordAuthProvider in favor of FIREmailAuthProvider.
+- Deprecates getTokenWithCompletion in favor of getIDTokenWithCompletion on
+  FIRUser.
+- Changes Swift API names to better align with Swift convention.
+
+# 2017-02-06 -- v3.1.1
+- Allows handling of additional errors when sending OOB action emails. The
+  server can respond with the following new error messages:
+  INVALID_MESSAGE_PAYLOAD,INVALID_SENDER and INVALID_RECIPIENT_EMAIL.
+- Removes incorrect reference to FIRAuthErrorCodeCredentialTooOld in FIRUser.h.
+- Provides additional error information from server if available.
+
+# 2016-12-13 -- v3.1.0
+- Adds FIRAuth methods that enable the app to follow up with user actions
+  delivered by email, such as verifying email address or reset password.
+- No longer applies the keychain workaround introduced in v3.0.5 on iOS 10.2
+  simulator or above since the issue has been fixed.
+- Fixes nullability compilation warnings when used in Swift.
+- Better reports missing password error.
+
+# 2016-10-24 -- v3.0.6
+- Switches to depend on open sourced GoogleToolboxForMac and GTMSessionFetcher.
+- Improves logging of keychain error when initializing.
+
+# 2016-09-14 -- v3.0.5
+- Works around a keychain issue in iOS 10 simulator.
+- Reports the correct error for invalid email when signing in with email and
+  password.
+
+# 2016-07-18 -- v3.0.4
+- Fixes a race condition bug that could crash the app with an exception from
+  NSURLSession on iOS 9.
+
+# 2016-06-20 -- v3.0.3
+- Adds documentation for all possible errors returned by each method.
+- Improves error handling and messages for a variety of error conditions.
+- Whether or not an user is considered anonymous is now consistent with other
+  platforms.
+- A saved signed in user is now siloed between different Firebase projects
+  within the same app.
+
+# 2016-05-18 -- v3.0.2
+- Initial public release.
