Resigning process

When installing an app on an iOS device the app has to be re-signed with the UDID of the device.

How Re-Signing Works?

On iOS, we replace the embedded provisioning profile with a wildcard profile and resign the app. Resigning the iOS app results in the removal of certain entitlements. This includes App Group, Associated Domains, Game Center, HealthKit, HomeKit, Wireless Accessory Configuration, In-App Purchase, Inter-App Audio, Apple Pay, Push Notifications, and VPN Configuration & Control.

To ensure the complete testing of your iOS application, we suggest you test the application on a physical iOS device before testing on our Device Cloud.

Tips while using Automated Signing:

  • Follow Apple Guidelines while configuring build parameters.
  • Build and Archive the application with Target as Generic Device.
  • Make sure Archived IPA file name does not have spaces/special characters.

Note: Resigning server will work only if Bundle ID is 'com.*'. If you have any other Bundle ID, resigning will not work. You have to then resign using manual resign process using UDID approach given below or change the Bundle ID to 'com.*'.

Please follow the below mentioned steps for resigning iOS app.

1. Login into pCloudy.com.

Manual Resigning using the UDID (Unique Device Identifier) of iOS Devices

If you are unable to do the automated resigning, then you can resign manually using the UDID.

UDID stands for Unique Device Identifier. Each iPhone or iPod Touch has a Unique Device Identifier (UDID), which is a sequence of 40 letters and numbers that is specific to your device. You can copy the UDID and paste it in your Apple Developer account to resign manually.

Follow the below mentioned steps to find the UDID:

  • Login with your credentials.
  • Go to 'DEVICES' tab.
  • Go to "UDID" to check the UDID.
