When creating a new project, I named it o-golfer (like the name of my project).Then I changed the name of the identity to Application

Now when I recreate it I get Apple LLVM 5.0 error because the cached precompiled header is trying to find it.Is there a way to remove this cached header and recreate it?I already tried to clean and rebuild the project … same error

  clang: error: no such file or such directory: '/Users/yves/Developpement/iOS7/OPTIMAL/o-golfer/o-golfer/o-golfer-Prefix.pch' 

Here is the error log:

Why Is Clang Removing Qikl When Using -O3?

Consider the following code#include #include #include #include TestClass class{Publicity:Int A = 0;Int B = 4;protected:Private:};int main (int argc, const char * argv []){Â std :: random_device randomDevice;Std :: mt19937 mersenneTwister (randomDevice ());Â distribution std :: uniform_int_distribution (1,255);Â for (size_t i = 0; i <10000000; i)A {Size_t const vectorSize = distribution (mersenneTwister) 1;Test TestClass * testVector (reinterpret_cast (malloc (vectorSize * sizeof (TestClass))));Â if (testVector [0] .A == 0x0ffeefed){Std :: cout << "Sorry, value reached." << std :: endl;Pause;} / * Yes * /Free (testVector);} / * Per * /Â return 0;}}Clang removes the for loop entirely with the -O3 optimizations. I'm a little surprised. Although testVector was just a junk file, I expected the loop to not be removed (in fact, there was no warning, only the parser detected that testVector contained spam).If I add a line that assigns a value to the random element testVector, the loop is not removed.PS I wanted to use a loop to test the execution speed of malloc and for free.

Should You Still Use The Out Keyword To Comment Out The Outputs Of Objective-C Methods?

Some headers still use the out keyword when declaring parameters for Objective-C methods, for example: `- (BOOL) setWLANChannel: (CWChannel *) Channel error: (out NSError **) NS_AVAILABLE_MAC error (10_7); `Is there a practical difference if it is a keyword (qualifier?) For ObjC / ObjC (ARC / no) -ARC present / missing), Swift, or AppleScript? The only relevant link I found is in the document “Objective-C Automatic Reference Counting for Clang” in Section 4.3.4: 4. If the parameter is not a validated parameter of an Objective-C method, * p is read and the result with primitive semantics is written in temporary. I don’t understand why “out” has such a meaning.
