Hello @Sápi Sándor ,
The screen pictures are not showing. This error means that you have a provisioning profile, but there is no signing identity to match. And your description tells me you are using Manual provisioning for Xamarin.iOS. If your profile has been imported in
%HOME%\AppData\Local\Xamarin\iOS\Provisioning\Profiles, make sure your certificate has been imported in
%HOME%\AppData\Local\Xamarin\iOS\Provisioning\Certificates as well. If not, you have to import one.
Please connect your iPhone to your MAC, then pair to mac, and select your iPhone under simulator drop-down menu for debugging.
And you could check if your profile and certificate are correct:
First, you could check if your Developer Certificate was expired: Open Keychain in your MAC, select Certificates and check if the Apple Development cer was expired.
Second, you could check if you selected the correct APP ID and Certificate when you created the provisioning profile. See the step 3-4 in New provisioning profile part. If your Wildcard is in the format
com.[DomainName].*, the APP ID and the Bundle Identifier in
info.plist of your project also should be in this format.
Finally, you could check if your app allows any capabilities, if so, you need to update the profile. See : Working with Capabilities in Xamarin.iOS
If you have any other issues, please feel free to let me know.
