How to Breakpoint at Function's return - Everett

Has a complex function with many code lines, internally has many returns, step debugging very slow, how to quickly find which line returned?

For example code:

void foo() {
    int i = arc4random() %100;
    
    if (i > 30) {
        if (i < 40) {
            return;
        }
        if (i > 77) {
            return;
        }
        if (i < 66) {
            return;
        }
    }
    
    switch (i) {
        case 0:
            return;
        case 1:
            return;
        case 2:
            return;
        case 3:
            return;
        case 4:
            return;
        default:
            return;
    }
}

int main(int argc, const char * argv[]) {
    foo();
    return 0;
}

Assume foo is a very long complex function with many returns, how to know which line returned?

Can use lldb’s breakpoint

breakpoint set -p return
or
br set -p return

First add breakpoint at foo’s first line

After breakpoint triggers, console input br set -p return

Then continue, will breakpoint at function’s return line.

Very interesting~
