thanks for reply, vs code i.e. visual studio code is a code editor which I used before. I wrote a cpp example program to show the difference. // code start (cpp) struct A{     public:     int varFst = 1;     int varSec = 2;     int funcAbc(){         return 1;     }     int funcAdc() {         return 2;     } }; void main(){     A a;     a.funcAbc();     a.funcAdc();     a.varSec; } // code end

typing "a.f" vs code will complete the highlight one with one tab, but in Xcode I need to press three times to make sure. "a.funcAbc()". I understand your explanation, but is it possible to make Xcode complete the highlight one with one tab?
