Hi, what name can I use as a bundle identifier so that I will not get this error message? Currently I am using: "daniel.de.Meine-Erste-App" But this does not work, it it seems not to be unique.... If I change it to something like daniel.de.asjflkasjfdlkajsdflkjasflkjas.Meine-Erste-App or something like this does also not work. As there is also the second failure-information: "Xcode couldn't find any iOS App Development provisioning profiles matching 'daniel.de.Meine-Erste-App'." I wonder if I have to do some settings in my account before... (setting up a provisioning profile This is the first time I try to bring an App to my local connected iPhone, so I appreciate any help! Thank you in advance, Daniel
