工程不认识xcframework.
需要将pod升级到1.10.0及其以上的版本，pod新版本才支持xcframework
检查pod版本
jgs:~ mac$ pod --version 1.8.4
具体解决方案：
- 替换ruby源
jgs:~ mac$ gem sources --remove https://gems.ruby-china.org/ source https://gems.ruby-china.org/ not present in cache jgs:~ mac$ gem source -a https://gems.ruby-china.com source https://gems.ruby-china.com already present in the cache jgs:~ mac$ gem sources -l *** CURRENT SOURCES *** https://gems.ruby-china.com/ https://rubygems.org/
2.保证只有一个ruby源，淘宝的源已经不更新维护了，现在使用ruby-china的源。多余的要移除：
jgs:~ mac$ gem sources --remove https://rubygems.org/ https://rubygems.org/ removed from sources jgs:~ mac$ gem sources -l *** CURRENT SOURCES *** https://gems.ruby-china.com/
3.验证是否替换成功：
gem sources -l
jgs:~ mac$ gem sources -l *** CURRENT SOURCES *** https://gems.ruby-china.com/
- 更新升级 Gem 版本
更新升级gem，gem不更新可能导致安装pod失败
sudo gem update --system
查看gem版本
gem -v
jgs:~ mac$ sudo gem update --system Password: Latest version already installed. Done. jgs:~ mac$ gem -v 3.0.3
5.安装CocoaPods
如果mac系统为OS X 10.11 以前安装命令为：
sudo gem install cocoapods // 安装cocoapods
Mac系统为OS X EL Capitan安装命令为：
sudo gem install -n /usr/local/bin cocoapods
j
jgs:~ mac$ sudo gem install -n /usr/local/bin cocoapods Fetching activesupport-5.2.6.gem Fetching ethon-0.14.0.gem Fetching public_suffix-4.0.6.gem Fetching ffi-1.15.3.gem Fetching addressable-2.8.0.gem Fetching cocoapods-core-1.10.1.gem Fetching typhoeus-1.4.0.gem Fetching cocoapods-downloader-1.4.0.gem Fetching nanaimo-0.3.0.gem Fetching rexml-3.2.5.gem Fetching xcodeproj-1.20.0.gem Fetching cocoapods-1.10.1.gem Successfully installed activesupport-5.2.6 Building native extensions.

6.等待其安装成功，用命令pod --version查看是否安装成功，如果成功会显示pod的版本。
jgs:~ mac$ pod --version 1.10.1
7.更新原来的工程，然后工程就能支持xcframework了，能运行工程成功了。
jgs:LChat mac$ pod update --verbose --no-repo-update
