I have a Vulkan project on Xcode which should open one window. I quit Xcode, open Xcode, open my project and then run my project. This results in one window opening. Then I close the window. Run the project and two windows open on top of each other. I again quit Xcode, open Xcode, open my project and then run my project. This results in one window opening. So in order to get my project to run properly (open only one window), I have to restart Xcode. I have an older Vulkan project I'm working on in Xcode, which opens properly. I'm setting up this project the same way as this older project. I am following the Setup Vulkan (MoltenVK) With GLFW On Mac Using Xcode - Vulkan Graphics/Games Programming Youtube video. https://www.youtube.com/watch?v=_j3ugZwT3Vc&t=19s I have my project up on Github, if someone could take a look and tell me what may be wrong with it. https://github.com/flocela/BlackSpider Thank you. : )

I'm a newbee at Vulkan and Xcode. I have my project on github https://github.com/flocela/OrangeSpider/ Whenever I run, two windows open instead of only one. I added testing, which means I have an OrangeSpider.xctestplan in the OrangeSpider/TestsOrangeSpider/ folder. This is my first time adding testing to an XCode project, so I think this may be where the problem is. I also get this error message: ViewBridge to RemoteViewService Terminated: Error Domain=com.apple.ViewBridge Code=18 "(null)" UserInfo={com.apple.ViewBridge.error.hint=this process disconnected remote view controller -- benign unless unexpected, com.apple.ViewBridge.error.description=NSViewBridgeErrorCanceled}
