error: target(mylib): toolchain not found!

当我在M4 Mac Mini(最新稳定版26.0.1)构建时，以下命令均可以运行：

xmake f -c -p macosx -a arm64 -m release
xmake -r

xmake f -c -p macosx -a x86_64 -m release
xmake -r

xmake f -c -p iphoneos -a arm64 -m release
xmake -r

但是ios模拟器目标构建失败：

rm -rf build
rm -rf .xmake

xmake f -c -p iphonesimulator -a arm64
xmake

得到报错如下（toolchain not found!）：

zsh build.sh 
error: target(mylib): toolchain not found!
checking for platform ... macosx
checking for architecture ... arm64
checking for Xcode directory ... /Applications/Xcode.app

[ 47%]: cache compiling.release src/main.cpp
[ 71%]: linking.release libmylib.a
[100%]: build ok, spent 0.292s

但是会在build里生成一个非ios相关的新目录：

build % tree macosx
macosx
└── arm64
    └── release
        └── libmylib.a

3 directories, 1 file

xmake.lua:

add_rules("mode.debug", "mode.release")

target("mylib")
    set_kind("static")
    set_languages("c11", "cxx17")
    add_includedirs({public = true})
    add_files("src/**.cpp")

src目录随便丢了个cpp函数：

#include <iostream>

int main1(int argc, char** argv) {
    std::cout << "hello world!" << std::endl;
    return 0;
}

xmake v3.0.4+20251023

要配置的东西应该都弄了，开发者协议命令之类的也搞了。SDK是有的：

% xcrun --sdk iphonesimulator -f clang
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang

我又查了下，似乎不支持这个platform。

xmake show -l platforms                                                                                     
watchos      msys         iphoneos
appletvos    harmony      wasm
cross        bsd          haiku
mingw        macosx       linux
android      applexros    windows
cygwin

那要如何构建iphonesimulator目标呢？
