Hi,
I am new to JUCE , I created a new GUI project using the Introjucer app below is the screenshot When I open te GUI in Xcode and run the target I dont get a GUI display.
Sorry, this is one of those questions where I just wouldn't know where to begin.. Sounds like you've created a cpp file containing a GUI class and are now expecting it to magically appear somewhere (?) without actually writing any code to use it. The GUI designer only generates C++ GUI classes for you, it's your job to actually use those classes in real code.
