If you start installing from the DeployGate application details page and fail on loading on the home screen, it may be due to the signature of the IPA file.

Please check if the provisioning profile is specified in "Signing & Capabilities> Signing" at Xcode Targets.

The procedure for setting Provisioning Profile in Xcode 15 is described below.

1. Select the project file and go to the Target Signing & Capabilities tab. Make sure Automatic manage signing is enabled from within the General tab.

If Automatically manage signing is enabled, Xcode automatically creates/uses provisioning profiles, so you can not specify them, but in ordinary cases, this will not be a problem.

If you want to specify a provisioning profile for any reason, you can do it by disabling this automatic manage signing.

2. To specify a provisioning profile with Automatically manage signing disabled, specify a specific provisioning profile in Signing & Capabilities Provisioning.

If you do not have a provisioning profile, you want to specify, select Settings from the Xcode menu.

In the next window that appears, select the Accounts tab, select the corresponding Apple account, then press Download Manual Profiles.

This will download the provisioning profile registered in the Apple Developer Center.

3. An IPA will be created. Archive it with "Product> Archive e" and then follow the Xcode instructions.

You can register provisioning profiles and associated certificates in the Apple Developer Center.

If the problem can not be solved by the method above or if you have more questions, please contact us at DeployGate support.
