Qt is dropping the SUPPORTED_PLATFORMS flag from the Xcode Project

johnc

I have updated to the latest Xcode and Qt. This has left me with deployment issues to iOS

xcodebuild: error: Unable to find a destination matching the provided destination specifier:
		{ generic:1, platform:iOS }

	Available destinations for the "app" scheme:
		{ platform:macOS, arch:x86_64 }
		{ platform:macOS, arch:i386 }
make: *** [xcodebuild-debug-device] Error 70

I can open the generated Xcode project file, set the parameter

SUPPORTED_PLATFORMS = "iphonesimulator iphoneos";

It then builds and deploys in Xcode.

However, every time I hit build in Qt Creator, it wipes the Xcode project file dropping the platform parameter.

Is there a way I can get this to stick by putting it in my Qt .pro file, or some other way I can fix this issue?

Fixed it by putting this in my project file

QT_SUPPORTED_PLATFORM.name = SUPPORTED_PLATFORMS
QT_SUPPORTED_PLATFORM.value = "iphonesimulator iphoneos"
QMAKE_MAC_XCODE_SETTINGS += QT_SUPPORTED_PLATFORM

Hi,

Out of curiosity, which version of Qt is that ?

johnc

Qt 5.9.1, Qt Creator 4.4.0.
It was working fine until I updated Xcode to the latest version ( 9.0.1 ).

Another person here did the same upgrade and his is working, so I don't think its a necessarily an issue with Qt or Xcode itself. I assume it is some obscure setting bug which is causing it for me, but I have been unable to find it.

We also compared Xcode project files generated by both boxes. His working version is also missing the SUPPORTED_PLATFORM flag. However, when this project file is opened in Xcode it says the supported platform in the build settings is "iOS", whereas mine says "macos". This is where I have to manually change it each time, or use my fix from above.

I think I have stumbled on something obscure.

Did you try to nuke the build folders and delete de .pro.user file ?

johnc

Yep. And created new empty projects as tests.
