Hello,I am new to ios development. On the internet I have found tutorials how to create a free (restricted) developer account however in this tutorials there are different descriptions how to register an iOS device with the acount in xcode in order to install apps that I develop.Is there any official tutorial from apple how to do this?Or can some member of Apple staff confirm that this tutorial https://developer.xamarin.com/guides/ios/getting_started/installation/device_provisioning/free-provisioning/ work for Xcode version 9.2, please?Thanks in advancePetra

Hi,my apps run on the iOSSimulator without problems and used to run on devices as well, but after updating to latest XCode-Version I am getting the above error message when trying to run an app on my iPhone 7. It says :"codesign wants to access key "access" in your bunch of keys . To allow this enter your password".... but my apple-Developer-ID-Password doesn't work. And until updating to latest XCode-Version I never had any problems with codesign when running an app on iPhone device.Any hints what's going wrong ?XCode Version 9.1 (9B55)iOS Version 11.1.2 (15B202)Latest High Sierra Version, macbook Pro 2015

(I posted this in the "Distribution >> App Submission and Review" forum 2 days ago but it has not received a response. Trying here...)I had to rebuild my iMac a few months ago and I restored from my Time Machine backup.I now need to make a change to an app but what used to compile without error is now failing at the codesign step with:Signing Identity: "-"As far as I can see, all of the account profiles are valid with expiry dates in the future. The only 'odd' thing is that some have a 'Download' button in the 'Action' column of the 'Provisioning Profiles' seciotn of the account details - when I select the "Download All Profiles" button, they turn grey but never seem to download or disappear (even after aiting for several hours!). Looking at the 'developer' web page, all of my certificates and provisioning profiles are all active.Any ideas welcomedThanksSusan
