Unsupported URL error on ionic 1 (ios devices only)

Ionic Framework
1

Please describ Hello. Unfortunately I needed to do a project with ionic 1. I did the project. It works flawlessly for Android for Web and for iOS Web. But the project file does not work on iOS devices. After passing the Splash Screen, it gives an “unsupported URL” error no matter what page it is. I couldn’t solve this problem.

I am getting this error in Xcode log:

Domain=RBSAssertionErrorDomain Code=2 "Specified target process does not exist" 
UserInfo={NSLocalizedFailureReason=Specified target process does not exist}

On the device this error:

Failed to load webpage with error: unsupported URL

Index.html:
