问题：
Building for iOS, but linking in .tbd file (/opt/theos/vendor/lib/CydiaSubstrate.framework/CydiaSubstrate.tbd) built for iOS Simulator, file '/opt/theos/vendor/lib/CydiaSubstrate.framework/CydiaSubstrate.tbd' for architecture arm64
把/opt/theos/vendor/lib/CydiaSubstrate.framework/CydiaSubstrate.tbd文件用文本打开，我用的是Sublime Text，删除archs后面的两项(, i386, x86_64)，就可以编译成功了。
