Ios support

Resolves #30

[CleanCut]

It looks like it almost worked for me. After installing Xcode, the iPhone simulator, and the required toolchains, a make run inside the mobile/ directory manages to build, but then dies trying to launch a simulator.

[snip]
    /usr/bin/touch -c /Users/nathan/rust/bevy_game_template/mobile/build/Build/Products/Debug-iphoneos/mobile.app

** BUILD SUCCEEDED **

xcrun simctl boot 3rd || true
Invalid device or device pair: 3rd
xcrun simctl install 3rd build/Build/Products/Debug-iphonesimulator/mobile.app
Invalid device: 3rd
make: *** [install] Error 148

I pushed the WIP manifest.yaml to switch from cargo-apk/Makefile and co. to xbuild. It currently requires my own xbuild fork though and doesn't work for iOS yet.

1. cargo install --git https://github.com/NiklasEi/xbuild
2. Install everything so that x doctor is happy
3. Run x devices, pick a device and
4. Run x run --device <device> in mobile

I'm happy to test for iOS again once you have it working for yourself.

I now see everything in my simulator. Apparently iOS requires WindowMode::BorderlessFullscreen.

I've also been working on extending the release flow for android and iOS builds. Since I don't have access to an iPhone at the moment, maybe someone could check a build for me?
Debug: https://github.com/NiklasEi/bevy_game_template/releases/download/ios_support/bevy_game_v0.1.0-test.12_ios.ipa
Attempt at release config: https://github.com/NiklasEi/bevy_game_template/releases/download/ios_support/bevy_game_v0.1.0-test.14_ios.ipa

xbuild still doesn't work for iOS, because I don't know how to propperly configure the executable.

I should be able to test this later today.

I was able to "install" both .ipa files by dragging them onto my iPhone's finder window, but trying to run them failed with the same error for both:

Unable To Install "mobile"
This app cannot be installed because
its integrity could not be verified.

I'm not super surprised -- because I don't know of any ad-hoc way of installing someone else's app without at least signing it with your own development certificate. Or going through the app store with testflight or an official release. But then, I am no iOS expert, maybe I just don't know what I'm supposed to do to make it work.

I am able to do make xcodebuild-iphone, make xcodebuild-iphone-release, and xcodebuild-archive-release which complete successfully.

make run works† -- but I usually have to manually launch Simulator.app in order to see the simulator UI, which is weird, because it popped up by itself at least once earlier, but it no longer seems to do that for me. 🤷🏻‍♂️

† As long as I keep adding in my Makefile patch that I suggested to fix the device id scraping

Thank you for testing again. I would have thought that there is a way to trust an unsigned app and install it anyways.
But then the new workflow for automatic exporting/signing/uploading I have been trying to build is more important than I thought.
Apple really doesn't make this easy...

[NiklasEi]

After a lot of trial and error, the new workflow to prepare and upload an ipa to app store connect finally works 🥳 . A friend of mine has verified via TestFlight that the build runs fine (although it doesn't seem to have any audio, but that a separate issue I guess).
The workflow also uploads the signed ipa to a release. This one should no longer cause the This app cannot be installed because its integrity could not be verified. error.

I forgot to mention in my last comment that audio had stopped working.

The workflow also uploads the signed ipa to a release. This one should no longer cause the This app cannot be installed because its integrity could not be verified. error.

Unfortunately, I still get the same error. 😕
