iOS Question Local Mac Builder corrupts keychain?

The build server creates a temporary keychain account and sets it to be the default keychain during compilation, unless you target the simulator.

It should be possible to switch to your keychain account from the Keychain app.

Thank you Erel,
I was not able to switch keychain accounts.
The problem somehow, seems to be solved now.
I noticed that after launching the local builder the login account on keychain just disappeared.
This deactivated the Apple ID.
The only way to have it back was rebooting.
I tried then to put the login keychain in a block status.
Launching again the builder I had three popups of processes "sharingd", "accountsd" and "identityservicesd" requesting permission to utilize the login keychain.
After that, keychain seemed to remain stable with the local builder active.
I'm not 100% sure on what all this means but I wanted to share the results in case someone else will fall in the same problem or to give you some hints in case there could be something to be done to the local builder .

Unfortunately the problem persists.
I thought it was solved, because yesterday for the whole day the builder was not affecting the login keychain account, but i found out that the account gets deleted as soon as i transfer the app to the phone. It's almost immediate.
No matter what i do the login account disappears.

Consider using the local builder with the simulator and the hosted builder with the real device.

Yes Erel,
I now mainly work with simulator..
Guess hosted builder is the only solution then. I'll go ahead and purchase a separate licence.
