E2E Decrypt

Store shared secret for private encrypted channels

* Removed empty Images.xcassets reference from`iOS Example Swift.xcodeproj`

* Consumption-test: Added shared code

* Consumption-tests: adding .gitignore

* Consumption-tests: adding first pass at Carthage tests.

* Consumption-tests: add macOS targets.

* Consumption-tests: resolved a couple of build warnings.

* Consumption-tests: updated scripts so they can be executed from any directory,

* Consumption-tests: adding `Carthage-MinimumXcode` for testing Xcode 11.

* Consumption-tests: moved important build settings into xcconfig.

* Consumption-tests: renamed Carthage-LatestXcode to Carthage-Latest and Carthage-MinimumXcode to Carthage-Minimum (since they verify more than just the Xcode version, also swift versions and deployment_targets)

* Consumption-tests: introduced a `config.xconfig` to shortcut to X_SUPPORTED_VERSIONS.xcconfig because this means that the xcodeproj's are identical and can be copied and pasted.

* Consumption-tests: added `run-tests-LOCALLY.sh`

* Consumption-tests: added `say` command for Xcode missing failure.

* Consumption-tests: updated projects so that `carthage-copy-platform-specific-frameworks.sh` is only invoked if its a Carthage based project (this will allow us to use the same project for Cocoapods).

* Consumption-tests: fixed `carthage-checkout.sh` in the event that working copy is clean.

* Consumption-tests: TEMPORARILY removed tvOS support so that things actually compile successfully.

* Consumption-tests:  ensure script exits with error code so a calling script does not continue if carthage update fails.

* Consumption-tests:  improved console output (so its clearer which test/scheme failed)

* Consumption-tests:  corrected accidental check in.

* Consumption-tests: added `-allowProvisioningUpdates` flag to `xcodebuild` so that it pulls latest provisioning profiles from Apple.

* Consumption-tests: moved `assignXcodeAppPathFor` function into dedicated file so it can be shared between scripts.

* Consumption-tests: added option of specifying flags with the `run-tests-LOCALLY.sh` script to skip certain aspects.

* Consumption-tests: rijigged some of the script operations in preparation of adding Cocoapods support.

* Consumption-tests: removed Carthage specific FRAMEWORK_SEARCH_PATHS out of project and into xcconfig.

* Consumption-tests: simplified checkout.sh scripts.

* Consumption-tests: removed hardcoding of X_SUPPORTED_XCODE_VERSION in favour of deriving the value from the directory name.

* Consumption-tests: further removal of hardcoded X_SUPPORTED_XCODE_VERSION in favour of deriving the value from the directory name.  Has allowed me to get rid of some scripts altogether.

* Consumption-tests: added Cocoapods-Latest support.

* *** Because Sodium has a MACOSX_DEPLOYMENT_TARGET of 10.11 we must increase our MACOSX_DEPLOYMENT_TARGET to 10.11. ***

* Consumption-tests: added Cocoapods-Minimum support.

* Consumption-tests: removed explicit reference to PusherSwift.framework from the projects.  This means all the projects are identical.

* Added `PusherSwiftWithEncryption` target/framework.

* Updated .travis.yml to use `xcode11`

* Updated SUPPORTED_PLATFORMS so that PusherSwift supports iOS, macOS and tvOS but PusherSwiftWithEncryption only supports iOS & macOS (since Sodium doesn't work with tvOS).

* Updated simulator device now we're using Xcode 11.

* Consumption-tests: Added *-WithEncryption support.

* Removed all DEPLOYMENT_TARGET values from *targets* because it is already defined in the *project* settings.

* Consumption-tests: removed `pod deintegrate` step because this was causing the project files to change on every run (and pollute the working copy)

* Consumption-tests: removed "Recovered References" from projects.

* Consumption-tests: Added SwiftPackageManager support.

* Removed `Sodium` from list of copied Carthage frameworks in `PusherSwiftTests` since its no longer used.  This was causing the tvOS tests to fail.

* Updated README.md to say that only Xcode 11 and above is supported.

* First draft of `Consumption-Tests/README.md`

* Further updates to `Consumption-Tests/README.md`

* `Consumption-Tests/README.md` anchor fixes.

* `Consumption-Tests/README.md` anchor fixes.

* Consumption-tests: Added scripts for CI.

* Removed tvos `PusherSwiftWithEncryption.podspec` since this framework does not support tvOS.

* Updated SWIFT_VERSION to 4.2 since this is what we say we support in the main README.md.  Also improvements to `Consumption-Tests/README.md`.

* Fixed a small issue with updating SWIFT_VERSION to 4.2

* Add tvOS tests (#250)

* Consumption-tests: fixed issues where certain DEPLOYMENT_TARGETs were harcoded in the project file and therefore not being derived from the xcconfig.  This has resolved the weird issue with not being able set the latest IPHONEOS_DEPLOYMENT_TARGET higher than 10.

* Consumption-tests: The previous commit/fix has also resolved an issue I was having with Cocoapods and has allow me to remove the custom setting of `MACOSX_DEPLOYMENT_TARGET`.
