我正在尝试在iOS真实设备上构建webdriveragent。它一直工作到昨天。从那以后我没有对盒子进行任何更新。我在编译时看到以下错误：

对于建筑arm64未定义的符号： “_OBJC_CLASS _ $ _ XCElementSnapshot”，从引用：l_OBJC _ $ _ CATEGORY_XCElementSnapshot _ $ _ FBIsVisible在XCUIElement + FBIsVisible.o l_OBJC _ $ _ CATEGORY_XCElementSnapshot _ $ _ FBUID在XCUIElement + FBUID.o l_OBJC _ $ _ CATEGORY_XCElementSnapshot _ $ _ WebDriverAttributes在XCUIElement + FBWebDriverAttributes.o objc- XCUIElement中的class-ref + FBWebDriverAttributes.o XCUIElement + FBUtilities.o中的objc-class-ref l_OBJC _ $ _ CATEGORY_XCElementSnapshot _ $ _ XCUIElement中的FBAccessibility + FBAccessibility.o l_OBJC _ $ _ CATEGORY_XCElementSnapshot _ $ _ FBScrolling in XCUIElement + FBScrolling.o ... ld：symbol（s ）找不到架构arm64 clang：错误：链接器命令失败，退出代码为1（使用-v查看调用）
我使用最新的Xcode和appium有人可以帮我解决这个问题吗？
在WebDriverAgentLib目标中的其他链接器标志中添加-Wl，-U，“_ OBJC_CLASS _ $ _ XCElementSnapshot”。
