Enable Client build for iOS simulator

[fortuna]

Currently our client doesn't run on the simulator because our dependencies are built for the device architecture.
We should migrate the dependencies to xcframeworks. Both Carthage and go-mobile already support that.
We will probably need to edit the xcode project.

• build(apple): Migrate Tun2Socks to xcframework #1271
• build(apple): Upgrade sentry-cocoa and migrate to xcframework #1268
• build(apple): Migrate CocoaLumberjack to xcframework #1262
• Move rsync call to a Cordova after_prepare hook

Those dependencies are specified in the plugin.xml. We will need to update that file to refer to the xcframework files

We may need to also edit the xcode project because I think we disable some architectures.

We may be able to migrate the Carthage dependencies to cocoapods, at least on ios, since Cordova seems to support it (see spec). Though it may be better to have a more unified architecture with macos and just use a xcframework (or migrate macOS to Cocoa pods somehow)

FYI, here is an attempt to generate the tun2socks xcframework: Jigsaw-Code/outline-go-tun2socks#85

To be validated.

Note that the iOS simulator does not support the NetworkExtension framework used to establish the VPN. A simulator build may be useful to test UI, but you may need to mock out the NE VPN functionality.

It turns out Sentry 4 only supports arm64 for iOS:

Sentry needs to be upgraded to version 5+.
Here is the migration info: https://docs.sentry.io/platforms/apple/migration/#upgrading-from-4x-to-5x

After updating Sentry and Tun2Socks, I was able to run on the simulator. However, I can't connect:

On the logs, I see:

2022-04-21 18:49:38.337288-0400 Outline[80153:11611325] Failed to start VPN
2022-04-21 18:49:38.340605-0400 Outline[80153:11607025] ERROR: could not connect to server XXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX: VpnPermissionNotGranted

[fortuna]

@alalamav any idea how I can grant the VPN permission to the app?

[fortuna]

This is done. We can now build for the simulator, even though the VPN doesn't work.
As far as I can tell, we can also build for Apple Silicon.

These commands now work after you created and prepared the ios platform with npm run action gulp build ios:

npx cordova compile ios --simulator
npx cordova compile ios --device

cordova run doesn't work because it calls prepare, which is broken without the rsync call.

@daniellacosse I believe we will need to tweak the build scripts to allow for building for the simulator. With the cordova CLI we could call cordova build --simulator ios
