Xcode compiler error, but iOS program compiles

Question

I am calling the code below in a C++ class.

void CurrentClass::doSomeProcessing() {
      printf("Hello World");
}

void CurrentClass::someMethod() {
      std::thread t(&CurrentClass::doSomeProcessing, this);
}

It seems that Xcode IDE throws the following error.

No matching constructor for initialization of 'std::thread'

But, the program compiles and runs without an issue.

Any ideas on how I can fix this issue?

I am guessing it is some setting in the build settings for my Xcode project??
