新建 target 需要 关闭 hardened runtime才可以调试 对比你可以调试的配置, 发现了这个解决方案

M1 11.2.1 (20D74) Xcode 12.4 (12D4e). 源码可以断点，但是main函数什么的不能断点。

macOS Ventura 13.3.1 (22E261)
Xcode 14.3 (14E222b)
13-inch, M1, 2020

xcode 11.7、系统macOS Big Sur 11.01运行781那个项目报错：
dyld: Symbol not found: _sel_hash

是最新系统的问题吗？

Xcode 12.2
MacOS 11..0.1
objc4-781 编译失败

First thank you for providing this debug version of objc runtime.

OS version: Monterey 12.5.1
MacBook Pro (Retina, 13-inch, Early 2015)
Processor 2.7 GHz Dual-Core Intel Core i5

Xcode Version 14.0.1 (14A400)

Build error is Unexpected character <U+1F92F>, which is the 🤯 symbol, as below pictures shows.

I tried to replace that symbol with some random integer, but it will cause dyld throw exception at runtime.

Any help is appreciated.

能否讲解一下支持iOS/Mac的objc配置内容

我看是支持了m1,但是在m1 电脑上面依然还是会奔溃哦

比如说我想暴露objc-runtime-new.h,我在objc这个target里把这个头文件拖拽到public的区域。编译不能通过，提示找不到"PointerUnion.h"头文件

运行的是objc4-781工程，报错
mac系统是11.0.1
xcode是12.1

大佬能帮忙分析下是啥问题吗？下面是报错的信息，感谢！

objc4-818.2 在MaxOS 12.2.1 运行奔溃:
Assertion failed: (sel_registerName(sel_getName(meth.name())) == meth.name()), function methodizeClass, file objc-runtime-new.mm, line 1536.
请问博主如何解决?

Mac os: 10.15.7
Xcode: 12.1

Cooci老师，781代码在main函数中打的断点可以生效，command+左键也可以调到源码中，但是在源码中_objc_rootAlloc、_objc_init这些方法里的断点全部不生效。

你好，感谢提供这么方便的调试工具。
请问下 Xcode 15.0，MacOS 14.0，Mac Studio iOS甄姬无法编译怎么处理？提示
Ad Hoc code signing is not allowed with SDK 'iOS 17.0',

Mac 也crash在这里

编译运行的时候找不到这个文件咋办

KCObjcBuild[80175:963663] Hello, World! KCObjcBuild was compiled with optimization - stepping may behave oddly; variables may not be available.

目前无法正确的使用断点，感觉整个是乱的，查过相关配置，是debug模式，并且优化等级为None

Mac 系统 12.0.1 Xcode版本13.2.1

盼望作者早日同步，解决 macOS 12 上无法运行的问题

https://github.com/apple-oss-distributions/objc4

同样希望博主能加上 CoreFoundation、libdispatch，拜托：
https://github.com/apple/swift-corelibs-foundation （可编译成功）
https://github.com/apple/swift-corelibs-libdispatch (不可编译成功)

在llvm-MathExtras.h文件中出现错误, 不知道什么原因:

有人碰到过这个错误吗

objc4-779.1 , KCObjcTest 中的main.m打断点无效 ，断点被忽略

报错如下：

老师你好，我这边用750的源码按照网上的教程编译，build没问题，但是运行的时候就会爆栈，请问是什么问题。。。。

It doesn't work in MacOS Big Sur
