The Jitsi team would like to thank @AliKarpuzoglu, @linuxpi and The Hopp Foundation for the initial effort and help throughout.

Swift has a longstanding bug where a framework and a type cannot be named the
same. We have somehow managed to not run into this, but it now seems to be
hitting us.

Since this is a breaking change, this starts the road for SDK 3.0.

Use Fastlane to get them from Apple after processing, them upload them.

Also make sure WebRTC dSYMs are included when uploading.

Time has come. We need to enable bitcode. It's optional for iOS targets, but
mandatory for the entire project if there is a watchOS target. Since we have a
watchOS target, it's time to enable it.

It complicates automated builds.

Signing wouldn't work, disabling it and enabling it again created these changes.
Oh well!

Load it at build time from a "dropbox.key" file. The file should contain the API
key in a single line.

Read it from the GoogleService-Info.plist file and apply it into Info.plist.

This is mostly implemented in the app, with the needed support in the SDK. Since
the app needs to donate intents and deal with creating NSUserActivity objects it
doesn't feel right to do this in a library. Instead, we donate the intents from
the app, but the SDK is ready to extract conference URLs from any intent which
was registered as a conference activity.

This also opens the door for eventually adding Handoff support.

This is done at the app level, not the SDK.

Currently 2 Firebase services are used:

  - Crashlytics
  - Dynamic Links

They are enabled in tandem, if the appropriate Google services file
(GoogleService-Info.plist on iOS or google-services.json on Android) is found.

Each service needs to be individually enabled in the Firebase console.

Also update the bundle ID since we don't release with that anyway.

WebRTC no longer actively fixes iOS 9 issues.

While having configuration-specific AppIcons may be of questionable use,
I'm more interested in using the Debug version for enterprise
distribution and the Release version for AppStore distribution.

Before, Jitsi Meet (the app) would only link with JitsiMeet.framework, which in
turn embedded WebRTC.framework. While possible, Apple doesn't allow apps with
nested frameworks to be submitted to the store. Now the app will link with
WebRTC.framework directly so there is no framework nesting.

A potential improvement here is to build WebRTC as a static library so it can
then be embedded in JitsiMeet.framework and completely hidden from the app.

1. Aligns the project structure of Jitsi Meet SDK for iOS with that for
   Android for better comprehension.

2. The command `react-native run-ios` uses the last Xcode project or
   workspace in the list of these sorted in alphabetical order. Which
   limits our freedom in naming. Thus having only an Xcode project in
   the root directory of the iOS project structure gives us back the
   freedom in naming.

3. Allows the Podspec to work for the app project in addition to the sdk
   project because we need Crashlytics in the app which is integrated
   via Cocoapods as well.

4. Further removes references to JitsiKit in the source code for the
   sake of consistent naming.
