“file uri scheme”

I'm trying to use XCode to debug a simple toy C++ program built using a Makefile (set up project using 'External Build System').Normally I'm able to debug and run, and use breakpoints within the editor. The way I did this was by going to Edit Scheme > Run > Use custom working directory, then checking the check box and specifying the directory of the executable. Except currently I'm not able to click in the text field or on the folder pop-up dialog at all to change this directory from blank.Such that, when I hit the build and run button with the check box checked I get a popup that asks Would you like to Run anyway? : The working directory (null) for scheme scheduler doesn't exist. Except I can't change the blank text field at all to fix this...I would add a screenshot of the options to clarify but I'm concerned about triggering moderation given this post I read about the forums [https://forums.developer.apple.com/thread/97547]

I have a sample SwiftUI iOS app. As shown in the screenshot below, my project has three configurations: Debug, MyDebug, Release. If I select the Debug or MyDebug scheme, I get a preview. But if I select the Release scheme, I get an error that says the following. ”***.app” needs -Onone Swift optimization level to use previews (current setting is -O) , where *** is the app name. It probably has nothing to do with the Preview error, but the Info.plist has a dictionary such that the key name is devMode, and the value is $(DEVMODE). And I have a user-defined setting as shown below. My ContentView has the following. import SwiftUI struct ContentView: View { @State private var state: String = var body: some View { VStack { Text(Hello, world!: (state)) } .onAppear { if let devMode = Bundle.main.object(forInfoDictionaryKey: devMode) as? String { print(Development mode: (devMode)) state = devMode } if let path = Bundle.main.path(forResource: Info, ofType: plist) { if let dict = NSDictionary(contentsO
