What domain to specify for iOS apps?

[vimpunk]

Hi,

I'm having trouble running the generated egui example, getting the following error when running cargo apple run:

note: Building targets in dependency order
/Users/mandreyel/x/ios-test/gen/apple/ios-test.xcodeproj: error: Communication with Apple failed: Your team has no devices from which to generate a provisioning profile. Connect a device to use or manually add device IDs in Certificates, Identifiers & Profiles. https://developer.apple.com/account/ (in target 'ios-test_iOS' from project 'ios-test')
/Users/mandreyel/x/ios-test/gen/apple/ios-test.xcodeproj: error: No profiles for 'com.example.ios-test' were found: Xcode couldn't find any iOS App Development provisioning profiles matching 'com.example.ios-test'. (in target 'ios-test_iOS' from project 'ios-test')
note: Run script build phase 'Build Rust Code' will be run during every build because the option to run the script phase "Based on dependency analysis" is unchecked. (in target 'ios-test_iOS' from project 'ios-test')

Based on the error message it looks like I'm supposed to sign up for the Apple Developer Program but I think it should be possible to just test manually on my iPhone, correct?

It seems it's related to the domain I'm entering during cargo mobile init. I'm not sure what I'm supposed to enter here so I just left it at the default example.com value.

Apologies if this is covered somewhere, haven't found anything. Thanks in advance.

I've finally gotten it to work.

It looks like the domain has to be globally unique (or associated with one's Apple) but otherwise it can be a made up domain as long as it's not example.com, which is obviously already taken.

Then you have to open xcode, click on the app name at the root of the file tree, there go to Signing & Capabilities tab and enable your developer profile if it isn't already.

Unrelated, but maybe it helps someone: for me there was an error when the app name contained spaces, it seems like that's not correctly parsed.
