Xcode 7.3 + Qt Creator 3.6.1: Deployment failed. The settings in the Organizer window of Xcode might be incorrect.
I read the suggestions for "Deployment failed" thread started 2 years ago, but none of them helped me.
I was using Qt 5.6 [Creator 3.6.1] on Mac 10.10 [Yosemite] with Xcode 7.2.1 OK until yesterday, when the iPad I was using was updated to latest iOS 9.3.1 and Xcode no longer worked. I upgraded to Mac 10.11.4 [El Capitan] and Xcode 7.3 and I can compile and run on iPad again today [I had to re-authenticate my ID on Xcode and re-authorized on iPad first as well as delete the old app on iPad].
However, when I try to run inside Qt Creator, it now complains with:
:-1: error: Deployment failed. The settings in the Organizer window of Xcode might be incorrect.
[I also created a copy of the project with different project name and I opened with Xcode to fix the provisioning and closed it and ran in Qt but I got the error above. With previous Xcode, this always allowed me to run via Qt OK.]
Is this a bug in Qt or I'm missing some additional steps to work with Xcode 7.3?
I did the same. after updating iPhone 6S to 9.3.1 I couldn't deploy from QtCreator.
I had to update my mac from 10.10.5 to 10.11 and to update Xcode to 7.3
Then in Xcode connected my iPhone, then Xcode did some '... downloading / processing of symbol files...'
Tested to run a project from Xcode - works
Then from Qt 5.6 / Qt Creator 3.6.1 could run apps on iPhone as before
I don't know previously but I can confirm that as well.
xcode 7.3, ios 9.3.x and El capitan
UPDATE: I issued a file on bugreport.
