'IPHONEOS_DEPLOYMENT_TARGET' is set to 7.0, but range is 8.0 to 13.2.99

Hi all.

First post here.

We are developing a hybrid Cardboard app, with Google Cardboard SDK for Unity / iOS (latest v. 1.200.1). Unity version 2019.2.x. We are using Cloud Build for iOS test process.

Our build is successful. However, the resulting app does not launch on iPhone (iOS 13.3) saying that version of the app is too old / not supported. The very same build done locally yields an app that launches correctly.

Going through the UCB logs we found these:

It appears that the 'GVRSDK' pod (as in Cocoapods) depends on GTMSessionFetcher and GoogleToolboxForMac; these pods however set an IPHONEOS_DEPLOYMENT_TARGET that is too old.

Are we on the right track? How can we set a custom IPHONEOS_DEPLOYMENT_TARGET that UCB will observe?

Is this something that needs to be addressed in PostProcessBuild at a Unity level? If yes, how?

Thank you in advance for your time and help.

It sounds like a potential issue with cloud build if it's working locally. You could probably fudge it a bit by setting the plist value directly or by modifying the xCode project in the PostProcessBuild like you mentioned. Here's some code that will set the minimumOSVersion (deployment target gets passed to this) in the plist file to 13.0:

Code (CSharp):

1. #if UNITY_IOS
2. using UnityEngine;
3. using UnityEditor.Callbacks;
4. using UnityEditor;
5. using UnityEditor.iOS.Xcode;
6. using System.IO;
7.  
8. // Post process for iOS build
9. public class AddMinOS
10. {
11.     [PostProcessBuild]
12.     public static void ChangeXcodePlist(BuildTarget buildTarget, string pathToBuiltProject)
13.     {
14.         UnityEngine.Debug.Log( "ChangeXcodePlist" );
15.      
16.         // Info.plist modifications
17.         {
18.             // Get plist
19.             string plistPath = pathToBuiltProject + "/Info.plist";
20.             var plist = new PlistDocument();
21.             plist.ReadFromString(File.ReadAllText(plistPath));
22.  
23.             // Get root
24.             var rootDict = plist.root;
25.  
26.             // Set minimum OS to 13
27.             var buildKeyMinOS = "MinimumOSVersion";
28.             rootDict.SetString(buildKeyMinOS, "13.0");
29.  
30.             // Write to file
31.             File.WriteAllText(plistPath, plist.WriteToString());
32.         }
33.     }
34. }
35. #endif
