Hello

Is it possible that the dialog box shown in this screenshot did not show up on your screen ?

This is baffling...

Hello

This error happens when the target directory of the xcopy command is a children of the source directory. It means a copiable resource was mistakenly detected. It would be interesting to find out which one and why.

Do you have the possibility to share that Xcode project with me so that I reproduce the problem ? Confidentiality is guaranteed.

If not, you can try running the build script in debug mode by holding down the Shift key when you click the Build button. A lot more info will appear on screen, until the point where it fails. At this point you should have the full log in the build.log file in the Xcode project directory. It will indicate the source and target directories. Once you know them, you'll need to investigate where they come from - I'll help you do that.

Well, if it's included in the resources to copy, it means this path appears somewhere in your Xcode project file (Unity-iPhone.xcodeproj\project.pbxproj) in the PBXCopyBuildPhase section. I suspect a problem with the Xcode project file at this point, and I guess it would (or *should*) also fail to build on Mac.

FYI you can open that .pbxproj file with a text editor. If you can't make sense out of it, then send it to me and I'll try to pinpoint the problem.

Send it to my email address, pm @ this domain.

I could reproduce the problem. It seems that the localization files are the cause of the issue.

% project.pbxproj

/* Begin PBXResourcesBuildPhase section */
		1D60588D0D05DD3D006BFB54 /* Resources */ = {
			isa = PBXResourcesBuildPhase;
			buildActionMask = 2147483647;
			files = (
				9D9DE4EA221D84E60049D9A1 /* Data in Resources */,
				56C56C9817D6015200616839 /* Images.xcassets in Resources */,
				E2F74BB4BC90D6D0C95A7400 /* LaunchScreen-iPhone.storyboard in Resources */,
				4B9145F3AA81D792E104961B /* LaunchScreen-iPhonePortrait.png in Resources */,
				19B34F58891B4EF4D60DF47B /* LaunchScreen-iPhoneLandscape.png in Resources */,
				E5D44EB18CC968758D9231A7 /* LaunchScreen-iPad.storyboard in Resources */,
				66DF4ABE8ADB1F62E9B6DCF9 /* LaunchScreen-iPad.png in Resources */,
				B06E4FFBB4AF2AD5831382BF,
			);
			runOnlyForDeploymentPostprocessing = 0;
		};
%

I see that the last resource "B06E4FFBB4AF2AD5831382BF" has been added by something else than the Unity editor (because it has no comment next to it). When looking up further that ID, I see its file reference:

%
B06E4FFBB4AF2AD5831382BF = {isa = PBXBuildFile; fileRef = C60A4653A6C5D7BFF3FAD160 /* I2 Localization */; };
%

Which in turns resolves to a PBXVariantGroup

%
		C60A4653A6C5D7BFF3FAD160 /* I2 Localization */ = {
			isa = PBXVariantGroup;
			children = (
				0D1A4CAFAC841ADAE12B5572 /* Localizable.strings */,
				22CF47378B22A456B4EF11BD /* InfoPlist.strings */,
				EBFC4CB783A6601289BC0B5B /* Localizable.strings */,
				30D0474AA8540C5D5414171B /* InfoPlist.strings */,

				36E94AB1A9B3AD399D155FE6 /* InfoPlist.strings */,
			);
			name = "I2 Localization";
			sourceTree = "<group>";
		};

At this point I'm unsure if it's the Xcode project file that is malformed, or if it's a bug in my parser. That's a possibility but I'd like to make sure. Can this project be built without problems on macOS ?

Possibly. But bogus Xcode projects do exist, too. Can you make the macOS test ?

Thank you Catalin, this is very valuable information. So a regression is confirmed in pbxprojparse. I'm going to check the differences between the codebases at these two points.

I think I got it correctly this time. I'm testing my changes...

@Catalin, would you mind please trying these updated pbxprojparse.exe and build script, and tell me whether your app localization works correctly ? If they do, I'll push a corrective update.

Thanks in advance for your feedback.

P.S. I have the feeling these PBXVariantGroups never really worked totally correctly in fact. I hope they will now.

I had no doubt that the "cycling copy" error was fixed, as I could test it, but what I wanted to know is: does the *localization system* of your app work properly ? :)

Those folders contain the translations for all UIKit elements, including the app name. But since Unity doesn’t use UIKit, only the translated app name is relevant here.

I’ll publish the update very soon. Thank you
