And that’s the way Apple recommends us to do it. What is better – manual or automated signing?Īs I already mentioned, Xcode can automatically generate all the necessary things for you. And at that point, you start to re-think your signing process. For example, when you are ready to build and ship a new release of your application, but it’s failing because of an expired profile, and the main administrator is on a vacation (seriously, this is from my personal experience) and cannot re-generate and update this Provisioning profile on the remote build machine. It’s important to remember to keep those Provisioning profiles always up-to-date so that the build process would not start to fail at the most inappropriate time. Newly registered device gets linked with re-generated Provisioning profile but Continuous Integration machine still uses old Provisioning profiles without the new device.Provisioning profile exceeds its expiration date and gets invalidated,.But eventually, most developers encounter issues with this setup. The developer just needs to update project settings and copy those files over to the remote machine only once. Download and copy all chosen Provisioning Profiles from the 2nd step to the remote build machine.Īt first, it seems easy and painless.Copy a valid Apple Development and/or Production Certificate to the remote build machine,.Provide specific Provisioning profiles in Project settings,.Uncheck Automatically manage signing checkbox in the Project settings,.To make an iOS project build automatically on a remote machine using manual signing configuration, we need to follow certain steps: Why doesn’t the developer rely on the Xcode built-in automation for this process? Don’t they trust Apple? One of the answers to these questions would be – “because of the Continuous Integration”. They are generating every necessary certificate and provisioning profile in Apple Developer Portal, downloading them and keeping them up-to-date manually. Since this feature has been around for a while, from time to time developers still tend to manually set up provisioning profiles in their projects. It is located in the project configuration – General tab: Xcode option to automatically manage signing Still manually… So, this new checkbox tells Xcode that you want everything to be set up automatically. When automatically managing signing assets, Xcode will create signing certificates, update app IDs, and create provisioning profiles. The signing system has been rewritten to include a new mode for automatically managing signing assets, in addition to a dedicated manual mode where the profiles for the target must be explicitly selected. When Apple released Xcode 8.0, it came with a new feature – Automatically manage signing checkbox, and the release notes say: So, how does Xcode know that you don’t want to do anything manually and just want to run the project out-of-the-box? It will register a new Bundle ID for your new project, create and download a new provisioning profile, and link it with your project, too. Now the only thing you need to do is create a new project, hit the Run button and relax because Xcode has learned how to do everything for you. And that’s all just to be able to run the freshly created Hello World application on a real device.īut time has passed and this process has evolved. It wasn’t so long ago when we needed to go to the Apple Developer Portal and manually generate certificates, manually create new Application Bundle IDs and for each of them – generate multiple provisioning profiles and install them on our machines, of course, manually. Every iOS (and not only iOS) developer has heard at least once about the magical and mystical process of iOS certificate signing and provisioning profile generation.
