Qt Creator can't connect to iPad

[peter-70]

I have two devices: iPhone and iPad. Qt connects to the iPhone without problems, but the connection to the iPad fails:

As you can see, the circle by "Current state" is yellow. It should be green!
Do you know what is wrong with the devices?

That's because your iPad is not in the "Ready to use" state :P

Why that's the case, can have a lot of reasons.

The following come to my mind:

• the Device needs to be unlocked
• your Mac needs to be "trusted"
• your device needs to be registered as developing device

To be honest, the easiest solution is to simply double click on the generated Xcode project and check from inside of Xcode what is wrong.

Yeah, you're surely right. It run's now, but to be honest, I don't know why :-(

I've started iTunes, and it instructed me to setup the iPad. After this, I created a mini app, and opened it in Xcode. Up and down... the run-buttons on Qt-Creator are green now.

Nevertheless I get an error:
:-1: error: Deployment failed. The settings in the Devices window of Xcode might be incorrect.

So I must see, what it is

Thank you very much for your advice!
