我发现是问题所在，是在Info.plist文件中，可执行文件(CFBundleExecutable)硬编码为"MyAppName".当我更改项目"名称，目标"名称和方案"名称时，此硬编码值未更改，但仍具有原始应用程序名称.

What I discovered to be the problem, was that in the Info.plist file the Executable File (CFBundleExecutable) was hard coded as "MyAppName". When I changed the Project name and Target name and Scheme name, this hardcoded value was not changed, but still had the original app name in it.

因此，我将Info.plist文件中的可执行文件(CFBundleExecutable)更改为此常量:

So I changed Executable File (CFBundleExecutable) in the Info.plist file to be this constant:

    ${EXECUTABLE_NAME}

问题解决了:)

我在另一个项目上再次发生了问题，但是以上内容已经设置为$ {EXECUTABLE_NAME}.

I had the problem occur again on a different project, however the above was already set to ${EXECUTABLE_NAME}.

所以我继续搜索，发现Build Settings > Build Options > Compiler for C/C++/Objective-C下的设置为UNSUPPORTED.

So I went searching and found that under Build Settings > Build Options > Compiler for C/C++/Objective-C was set to UNSUPPORTED.

我将此设置更改为DEFAULT，问题已解决:)

I changed this setting to DEFAULT and the problem was solved :)

我又遇到了问题，以上两点都没有解决.

I had the problem occur again and the above two things did not fix it.

因此，我去确保从任何Target Membership中都删除了(未选中)info.plist，这解决了问题.似乎有多种原因会导致此问题，因此请尝试所有解决方案！

So I went and made sure that the info.plist was removed (unticked) from any Target Membership, and this solved the problem. It seems that there are multiple things that will cause this issue, so try all the solutions!
