Alright, I have some suspicions that I've signed it alright (even though I still think that no network calling part may be due to entitlements for network calling) and deducted it to be hardened runtime problem. I've tried for a few hours to open my freshly built Unity launcher in Xcode, but I just don´t know how to successfully do it. I only see tutorials on YouTube for iOS which, after building, come with Xcode file which we can then open. The launcher is for Mac and Mac only. Can you please help me how to open it, tick hardened runtime exceptions so I can check which ones I need and which don´t, sign it and then build it? If this doesn´t work, I will call technical support because I have a deadline to meet. How smart is it to do such thing for such problem? If I do happen to call them, how much will they be able to assist me and solve my issues? An operator for developer support said that we have 2 calls towards technical support.
