Last updated October 13, 2022 by Appdome


Signing iOS apps is required before the app can be installed on a mobile device. A valid signature ensures the integrity of an app and stands as proof that the app has not been tampered with. Your best option is to sign secured iOS Apps without Xcode on Appdome.

This Knowledge Base article covers how to sign iOS apps using Appdome’s built-in Sign workflow.

We hope you find it useful and enjoy using Appdome!

Why Sign Secured iOS Apps Without Xcode

As an Appdome user, you can sign any Appdome-built app either by using Appdome’s built-in signing capabilities or using your own mechanism outside of Appdome. It’s your choice. However, If you wish to deploy apps from Appdome, the process is quick and easy for any iOS app, including Native iOS, hybrid apps and non-native apps built-in Xamarin, Cordova, React Native, Ionic and more. Deploying apps from Appdome will leverage unique capabilities such as Automatic deployment of Fused apps into the Apple App Store and Leading EMM Stores.

3 Easy Steps to Sign Secured iOS Apps Without Xcode

Follow these step-by-step instructions to sign secured iOS Apps without Xcode.

  1. Select the Sign Tab.
    Note: a blue underline will appear showing the step is active.
  2. Within Sign, follow these 3 easy steps:
    1. Select On Appdome as the signing method.
    2. Upload your P12 Certificate File, P12 Certificate Password, and Provisioning Profile.
    3. Click Sign My App.


If your secured app contains any Extensions or Frameworks, multiple provisioning profiles will be required. Upload Provisioning Profiles to match the required entitlements for each Extension or Framework. The best practice is to upload a Provisioning profile to match each executable in the app. Read more information on signing apps with Extension or Frameworks.

If Appdome-GO or Appdome-DEV are enabled on your account, you will be presented with an option to save the signing credentials for the current template. Click “Save” if you wish to save the credentials for this Template. Notice, if you click “Skip”, your signing credentials will not be saved and will be required every time this Template is used to Build an app.

Appdome makes signing ios apps on Appdome easy

When you click Sign My App, Appdome will analyze the built app’s extensions, frameworks are resources and calculate a checksum that represents an exact state of each component within the app. Embedding the checksum into the app’s executables will ensure that the app can’t be modified or tampered with once the signing is complete.
