我也遇到了这个问题，解决了吗

[shinyYangYang]

you need update class-dump. support Swift https://github.com/BlueCocoa/class-dump

@shinyYangYang 你好，链接失效了 有备份么

直接解决

• 原因：此restore-symbol依赖于class-dump，而此处的class-dump不支持swift

• 解决办法：把restore-symbol中的class-dump换成支持swift的版本

• 具体步骤：

• 先切换到swift-binaries的branch -》确保代码支持swift

• 再去参考：iOS 逆向入门 - 符号恢复及反汇编 | Darren's Blog，去注释掉：Source/CDObjectiveC2Processor.m中的loadClassAtAddress中的2行NSParameterAssert

- (CDOCClass *)loadClassAtAddress:(uint64_t)address;
{
。。。
        // NSParameterAssert(moduleName.length == length);
。。。
        // NSParameterAssert(className.length == length);

更高级更好的解决
