weird signing issue when debuging on iphone

Hello all,

I've got a strange behavior when I debug on my iphone. Every time I launch a new debug session, I have to clean my project or I get a signing issue :

[ERROR] :  Failed to install app on device (0xe8008017)
[ERROR] :  Chances are there is a signing issue with your provisioning profile or the generated app is not compatible with your device

It takes me ages to test my app, I need to rebuild every times.

Thanks for your help,

Sylvain
