-# App Delegate Swizzler
-
-## Overview
-
-The App Delegate Swizzler swizzles certain methods on the AppDelegate and allows interested parties
-(for eg. other SDKs like Firebase Analytics) to register listeners when certain App Delegate methods
-are called.
-
-The App Delegate Swizzler uses [isa swizzling](https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/KeyValueObserving/Articles/KVOImplementation.html)
-to create a dynamic subclass of the app delegate class and add methods to it that have the logic to
-add multiple "interceptors".
-
-Adding interceptors to the following methods is currently supported by the App Delegate Swizzler.
-
-* `- (BOOL)application:openURL:options:` [Reference](https://developer.apple.com/documentation/uikit/uiapplicationdelegate/1623112-application?language=objc)
-
-Note: This method is added only if the original app delegate implements it. This prevents a bug
-where if an app only implements application:openURL:sourceApplication:annotation: and if we add the
-`options` method, iOS sees that the `options` method exists and so does not call the
-`sourceApplication` method, which causes the app developer's logic in `sourceApplication` to not be
-called.
-
-* `- (BOOL)application:openURL:sourceApplication:annotation:`
-    [Reference](https://developer.apple.com/documentation/uikit/uiapplicationdelegate/1623073-application?language=objc)
-
-* `- (void)application:handleEventsForBackgroundURLSession:completionHandler:`
-    [Reference](https://developer.apple.com/documentation/uikit/uiapplicationdelegate/1622941-application?language=objc)
-
-* `- (BOOL)application:continueUserActivity:restorationHandler:`
-    [Reference](https://developer.apple.com/documentation/uikit/uiapplicationdelegate/1623072-application?language=objc)
-
-We are looking into adding support for more methods as we need them.
-
-## Adopting the swizzler
-
-To start using the app delegate swizzler to intercept app delegate methods do the following:
-
-The following assumes that you are an SDK that ships using Cocoapods and need to react to one of the
-app delegate methods listed above.
-
-1. Add a dependency to the app delegate swizzler - `GoogleUtilities/AppDelegateSwizzler:~> 5.2`. We
-follow Semantic Versioning.
-
-2. Create an interceptor class that implements the `UIApplicationDelegate` and implements the
-methods you want to intercept. For eg.
-
-MYAppDelegateInterceptor.h
-
-```objc
-
-#import <Foundation/Foundation.h>
-#import <UIKit/UIKit.h>
-
-NS_ASSUME_NONNULL_BEGIN
-
-/// An instance of this class is meant to be registered as an AppDelegate interceptor, and
-/// implements the logic that my SDK needs to perform when certain app delegate methods are invoked.
-@interface MYAppDelegateInterceptor : NSObject <UIApplicationDelegate>
-
-/// Returns the MYAppDelegateInterceptor singleton.
-/// Always register just this singleton as the app delegate interceptor. This instance is
-/// retained. The App Delegate Swizzler only retains weak references and so this is needed.
-+ (instancetype)sharedInstance;
-
-@end
-
-NS_ASSUME_NONNULL_END
-
-```
-
-MYAppDelegateInterceptor.m
-
-```objc
-#import "MYAppDelegateInterceptor.h"
-
-@implementation MYAppDelegateInterceptor
-
-+ (instancetype)sharedInstance {
-  static dispatch_once_t once;
-  static MYAppDelegateInterceptor *sharedInstance;
-  dispatch_once(&once, ^{
-    sharedInstance = [[MYAppDelegateInterceptor alloc] init];
-  });
-  return sharedInstance;
-}
-
-- (BOOL)application:(UIApplication *)application
-            openURL:(NSURL *)URL
-            options:(NSDictionary<NSString *, id> *)options {
-
-  [MYInterestingClass doSomething];
-
-  // Results of this are ORed and NO doesn't affect other delegate interceptors' result.
-  return NO;
-}
-
-- (BOOL)application:(UIApplication *)application
-            openURL:(NSURL *)URL
-  sourceApplication:(NSString *)sourceApplication
-         annotation:(id)annotation {
-
-    [MYInterestingClass doSomething];
-
-  // Results of this are ORed and NO doesn't affect other delegate interceptors' result.
-  return NO;
-}
-
-#pragma mark - Network overridden handler methods
-
-- (void)application:(UIApplication *)application
-    handleEventsForBackgroundURLSession:(NSString *)identifier
-                      completionHandler:(void (^)(void))completionHandler {
-
-  // Note: Interceptors are not responsible for (and should not) call the completion handler.
-  [MYInterestingClass doSomething];
-}
-
-#pragma mark - User Activities overridden handler methods
-
-- (BOOL)application:(UIApplication *)application
-    continueUserActivity:(NSUserActivity *)userActivity
-      restorationHandler:(void (^)(NSArray *restorableObjects))restorationHandler {
-
-  [MYInterestingClass doSomething];
-
-  // Results of this are ORed and NO doesn't affect other delegate interceptors' result.
-  return NO;
-}
-
-@end
-```
-
-3. Register your interceptor when it makes sense to do so.
-
-For eg.
-
-```objc
-
-// MYInterestingClass.m
-
-#import "GoogleUtilities/AppDelegateSwizzler/Public/GoogleUtilities/GULAppDelegateSwizzler.h"
-
-...
-
-- (void)someInterestingMethod {
-    ...
-
-    // Calling this ensures that the app delegate is proxied (has no effect if some other SDK has
-    // already done it).
-    [GULAppDelegateSwizzler proxyOriginalDelegate];
-
-    MYAppDelegateInterceptor *interceptor = [MYAppDelegateInterceptor sharedInstance];
-    [GULAppDelegateSwizzler registerAppDelegateInterceptor:interceptor];
-}
-```
-## Swizzling of App Delegate APNS methods
-
-Swizzling of the APNS related App Delegate methods may lead to an Apple review warning email about
-missing Push Notification Entitlement during the app review process
-(like here: https://github.com/firebase/firebase-ios-sdk/issues/2807) if Push Notifications are
-actually not used by the app. To avoid the warning the methods below are not swizzled
-by `[GULAppDelegateSwizzler proxyOriginalDelegate]`:
-
-```objc
-
-- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken;
-
-- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error;
-
-- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo;
-
-- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler;
-```
-
-If you need to swizzle these methods you can call
-`[GULAppDelegateSwizzler proxyOriginalDelegateIncludingAPNSMethods]`. The method can be safely
-called instead or after `[GULAppDelegateSwizzler proxyOriginalDelegate]`.
-
-## Disabling App Delegate Swizzling by App Developers
-
-Sometimes app developers that consume our SDKs prefer that we do not swizzle the app delegate. We've
-added support for developers to disable any sort of app delegate swizzling that we may do, and this
-is achieved by adding the Plist flag `GoogleUtilitiesAppDelegateProxyEnabled` to `NO` (Boolean). If
-this is set, even if you call `[GULAppDelegateSwizzler proxyOriginalDelegate]`, it won't have any
-effect.

-          that such additional attribution notices cannot be construed
-          as modifying the License.

-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.

-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a

-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-

-Comment from
-<a href="http://iphonedevwiki.net/index.php/Crack_prevention">iPhone Dev Wiki
-Crack Prevention</a>: App Store binaries are signed by both their developer
-and Apple. This encrypts the binary so that decryption keys are needed in order
-to make the binary readable. When iOS executes the binary, the decryption keys
-are used to decrypt the binary into a readable state where it is then loaded
-into memory and executed. iOS can tell the encryption status of a binary via the
-cryptid structure member of LC_ENCRYPTION_INFO MachO load command. If cryptid is
-a non-zero value then the binary is encrypted.
-
-'Cracking' works by letting the kernel decrypt the binary then siphoning the
-decrypted data into a new binary file, resigning, and repackaging. This will
-only work on jailbroken devices as codesignature validation has been removed.
-Resigning takes place because while the codesignature doesn't have to be valid
-thanks to the jailbreak, it does have to be in place unless you have AppSync or
-similar to disable codesignature checks.

-# Google Utilities
-
-## Overview
-
-The GoogleUtilities pod is a set of utilities organized into CocoaPods subspecs.
-See the [podspec](../GoogleUtilities.podspec) for a summary of what utilities
-are currently included. They're used by Firebase and other Google products.
-
-Direct usage by non-Google products and CocoaPods is **NOT** currently
-recommended or supported in general.
-
-**However**, we do specifically recommend that non-Google SDKs can use the App Delegate Swizzler to hook into app delegate methods as this reduces conflicts with multiple SDKs trying to do the same.
-
-Instructions on how to adopt the app delegate swizzler for use by your SDK are available [here](./AppDelegateSwizzler/README.md).
-
-## Development
-
-Follow the subsequent instructions to develop, debug, unit test, and
-integration test FirebaseFunctions:
-
-### Prereqs
-
-- At least CocoaPods 1.7.0
-
-### To Develop
-
-- Run `pod gen GoogleUtilities.podspec`
-- `open gen/GoogleUtilities/GoogleUtilities.xcworkspace`
-
-OR these two commands can be combined with
-
-- `pod gen GoogleUtilities.podspec --auto-open --gen-directory="gen" --clean`
-
-You're now in an Xcode workspace generate for building, debugging and
-testing the GoogleUtilities CocoaPod.
-
-### Running Unit Tests
-
-Choose the one of the Tests* schemes and press Command-u.

-//  GTMHTTPServer.h
-//
-//  This is a *very* *simple* webserver that can be built into something, it is
-//  not meant to stand up a site, it sends all requests to its delegate for
-//  processing on the main thread.  It does not support pipelining, etc.  It's
-//  great for places where you need a simple webserver to unittest some code
-//  that hits a server.
-//
-//  NOTE: there are several TODOs left in here as markers for things that could
-//  be done if one wanted to add more to this class.
-//
