"Cross-compiling for iOS on Linux" Not up-to-date documentation and assembly problem

[Valeryn4]

Godot version: 3.2+

OS/device including version: iPhone all and Linux Ubuntu 18 LTE

Issue description: Apple does not provide a “DMG” file. They provide a "XIP" file. Need instructions on how to unpack XIP

I asked a friend from his MacBook, the source code of the SDK Xcode. Build error:

Other modules are built without error.

Your SDK version is too old for ARKit support (and for publishing any game on the current App Store).

Your SDK version is too old for ARKit support (and for publishing any game on the current App Store).

This is the latest version of the SDK.

ARKit success:

The problem with the main module.

You're targeting SDK 9 here:

IPHONE_SDK="${HOME}/dev/IPhoneSDK/iPhoneOS9.1.sdk"

[Valeryn4]

Application\Xcode.app\Developer\Platforms\iPhoneOS.platform\Developer\SDKs\iPhoneOS.sdk* Application\Xcode.app\Developer\Toolchains\XcodeDefault.xctoolchain\usr\include\c++* I copied from the last Xcode. I copied it directly from the macbook

I acted according to the instructions, targeting IOS 9.1 In the last build, I disabled Arkit: module_arkit_enabled=no But the problem persists

[Valeryn4]

ARKit is going to a separate module. This module are not part of the main library.

[Valeryn4]

I am now rebuilding SDK for version 13.0. I’ll tell you exactly in an hour. But there is a problem in the documentation, it is too old.

If you just rename this file, everything seems to work ... (need testing)

build.sh ~/dev/IPhoneSDK/iPhoneOS13.0.sdk.tar.xz arm64 cp bin to iostoolchain_13.0_arm64/usr/

Presumably can be closed?
