Error parsing reference: "Xcode:7.0" is not a valid repository/tag

Tried executing the command
$docker build -t=test .
I get the below error

$ docker build -t=sample-ios-app .
Sending build context to Docker daemon 91.65 kB
Step 1 : FROM Xcode:7.0
Error parsing reference: "Xcode:7.0" is not a valid repository/tag

My Xcode version is 7.0.2

Can you help me out here.

I think the image called Xcode:7.0 has been destroyed!
I am a newer for the docker and I am very happy if I can use docker for iOS app, so I searched google to be here.
When I searched for Xcode:7.0 in the docker's repository the result is:

bogon:my-first stone$ docker search Xcode

There is no XCode image and there never was one.
Similar to #10 you need to run everything via a fake docker server. It presents a fake Xcode: base. based on your installed xcode version
