MobileGestalt no access to InverseDeviceID

Question

This happens with every app when I try to use OpenGLES on my iPhone7+ with iOS10.3. But it works without any problems on my iPho

Answer 1

I got this console warning message because of issues with multiple Apple Developer accounts. Evidently you cannot have a sandbox account with an existing Apple Developer account. I didn't try to create a sandbox account but it seems to check my default account, which is also an old Apple Developer account that I don't use and hence is no longer entitled. This issue has been reported to Apple many times by other people and I have not yet seen a solution.

My workaround to suppress this warning was to set the OS_ACTIVITY_MODE environment variable to disable in my scheme settings. You can click on the app name and then click Edit Scheme... or from the top menu you can click Product->Scheme->Edit Scheme... :

Then you edit the "Run" settings and add the environment variable OS_ACTIVITY_MODE and set it to disable:

NOTE: Be sure to set this environment variable to enable before you submit your app so that you can see if there are other warnings. There may be other warnings you should fix before you submit your app to the App Store.
