Xcode15，iOS17的Simulator的libstdc+

升级为Xcode15后，iOS17的Simulator，如手动下载安装模拟器

并采用以下方式安装模拟器，会以镜像形式加载模拟器，镜像形式安装不能修改Lib目录，不能手动覆盖libstdc++.6.0.9.tbd、libstdc++.6.tbd、libstdc++.tbd。：

xcode-select-s/Applications/Xcode.appxcodebuild-runFirstLaunch xcrun simctl runtimeadd"~/Downloads/iOS_17_Simulator_Runtime.dmg"

需采用以下步骤安装模拟器：

    1.去这里选择下载iOS17的模拟器文件Download

    2.双击iOS_17_Simulator_Runtime.dmg文件，等待打开后，逐层找到Runtimes文件夹。

    3.选择 Xcode 15 App，然后右击选择Show Package Content，通过Contents —> Developer —> Platforms —>        iPhoneOS.platform —> Library —> Developer —> CoreSimulator，找到Profiles文件夹。

    4.将第 2 步的Runtimes文件夹拷贝到第 3 步的Profiles文件夹中。

    5.打开/重启 Xcode 15，此时模拟器已成功安装。

基于github上的libstdc。执行以下脚本来实现覆盖libstdc++.6.0.9.tbd、libstdc++.6.tbd、libstdc++.tbd

xocde15.sh

#!/bin/bash

# Asking sudo

if [ $EUID != 0 ]; then   

    sudo "$0" "$@"   

    exit $?

echo '1'

sudo cp 1/* /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS\ 17.2.simruntime/Contents/Resources/RuntimeRoot/usr/lib/

echo '2'

sudo cp 2/* /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib/
