Hello guys i want to test my mobile game on ios but something wrong. I need help 
Hello Emir. The error messages say:
Your deployment target is set to 11.0 but the supported builds are 12.0 - 18.2.99
There is no signing certificate found matching the team id
Your provisioning profile has the app id named as something different than the bundle id
Also there is a note that it is disabling previews because it expects Swift Optimization to be one thing but it is another thing
When you open the project in Xcode you need to find these fields, like build target and set it to at least 12, make sure you have a signing certificate, make sure the app id is set correctly.
I wish I can be more specific but I rarely build an app for iOS since I do not have an Apple Developer account and the most I can do is build an app to be deployed on my own device for testing purposes. So every time I build one, it usually takes several moments of sorting through the pages of build settings to get all the fields correct, and I usually have to refer to a Youtube tutorial or article on the web to make sure I am doing it right.
