Xcode command line tool - how to work in terminal?

Question

When you create a command line tool project in Xcode, you get this, in main.m:

#import <Foundation/Foundation.h> int main(int argc, const char * argv[]) { @autoreleasepool { // insert code here... NSLog(@"Hello, World!"); } return 0; } 

I can run this from Xcode. But I want to compile it so that I can run it from Terminal. What are the steps?

Answer 1

Assuming your executable has the name "my_program" and it is in the directory "/ foo / bar / Debug":

 cd /foo/bar ./my_program 

If you don’t know how to find the program file, you can right-click it (for example, “product”) and “Show in Finder”, as shown in this screenshot:

Answer 2

You can launch the terminal every time you launch the application by editing the circuit. I believe this has become available with Xcode 8.0.

• Edit Scheme Access

  

• Switch Console from Use Xcode to Use Terminal

  

Answer 3

In Xcode 9, you should do the following:

• instead of the “editing scheme” click “new scheme”, give it a name and save
• now select the new scheme you just created and click on the "edit" scheme '
• go to the "Information" tab and in the "Executable" menu select "Other ..."
• in the file window, go to the search input field and enter "terminal" and click on the icon when you find it. You should now see "Terminal.app" in the "Executable file" field
• go to the "Arguments" tab, click "+" and copy and paste this line there: ${BUILT_PRODUCTS_DIR}/${FULL_PRODUCT_NAME}
• click "close" and run your program with your new scheme.

Typically, Xcode will open a terminal for you. If not, you can also disable all debugging-related fields on the Information tab. Hope this helps!
