When it comes to swift app development, debugging can be a tedious and time-consuming process. That's why we're excited to introduce SimpleDebugger, a lightweight in-process debugger that makes it easy to set breakpoints and respond when they're hit.

The Power of Breakpoints

Breakpoints are an essential tool for any developer looking to optimize their code. With SimpleDebugger, you can quickly set breakpoints at specific locations in your app's codebase using the setBreakpoint method. This allows you to pause execution at a specific point and inspect the state of your program.

Hooking Functions

In addition to setting breakpoints, SimpleDebugger also enables function hooking, which is similar to lightweight Frida functionality. You can use this feature to modify or intercept existing functions in your app. For example, you might want to log every time a particular function is called, or redirect the flow of execution to a custom handler.

Setting Up Your Debugger

To get started with SimpleDebugger, simply create an instance of the class and start setting breakpoints using the setBreakpoint method. You can also set up exception callbacks to handle when your breakpoints are hit. For example, you might want to print out information about the CPU state or thread that triggered the breakpoint.

Example Code

Let's take a look at some sample code that demonstrates how to use SimpleDebugger to create a basic debugger and add one breakpoint:

`

#include

void myFunction() { printf("Hello world\n"); }

void breakpointCallback(arm_thread_state64_t state, std::function sendReply) {

printf("Got breakpoint with PC: 0x%llx\n", state.__pc);

sendReply();

}

attribute((constructor)) void example(void);

attribute((constructor)) void setup() {

SimpleDebugger *debugger = new SimpleDebugger();

debugger->setExceptionCallback(breakpointCallback);

debugger->setBreakpoint((vm_address_t) &myFunction);

// You must call start debugging to set up the exception server.

debugger->startDebugging();

// The breakpoint handler will run before myFunction

myFunction();

}

`

Conclusion

SimpleDebugger is a powerful tool for swift app development that enables you to create custom debuggers and add breakpoints to your code. By using this lightweight in-process debugger, you can optimize your code and improve the overall performance of your app.
