Ionic cloud build: android & ios

I created new ionic app and added some test data there. I’ve added Ionic Services Then i created a securite profile without adding any certificates etc…

When i try to build android: all is ok.
But when i try to build ios, i get: Selected security profile does not have credentials for the selected platform. ( CLI v2.2.3)

Is it possible somehow to build debug apps in cloud without having a developer account from apple?

No. To run the development/debug build you have to attach your device to the provisioning profile (app is only allowed to run on connected devices) which requires a provisioning profile and certificates which you only get in the Apple Developer area.
