iOS apps must be signed to run on real devices. In App Center, this process requires uploading valid signing files generated using Apple's code signing process. You must be able to successfully sign a valid app package locally before attempting to in App Center.
Signing files
The Apple IIGS (styled as IIGS), the fifth and most powerful of the Apple II family, is a 16-bit personal computer produced by Apple Computer, Inc.While featuring the Macintosh look and feel, and resolution and color similar to the Commodore Amiga and Atari ST, it remains compatible with earlier Apple II models. Emails sent from an iPhone, by default, are signed 'Sent from my iPhone,' which almost seems like a disclaimer in case the email has spelling or formatting errors. If your goal is to look professional while corresponding with coworkers or potential employers, then you're better off removing the signature completely and just typing your name out. If the sender has specified that an adult signature is required, you cannot authorize delivery release online. You can, however, redirect it to a UPS customer center. You also cannot authorize release online if you’ve added instructions to your UPS My Choice preferences for deliveries to be left with an individual, such as a concierge.
Warning
App Center doesn't support signing files with special characters or symbols in the name. For example, accented characters like Ç, Ã or symbols like /.
TLS server certificates and issuing CAs must use a hash algorithm from the SHA-2 family in the signature algorithm. SHA-1 signed certificates are no longer trusted for TLS. TLS server certificates must present the DNS name of the server in the Subject Alternative Name extension of the certificate. In help info on apple website: Option 1: Pre-sign with Apple.

- In-House: for In-House app distribution (the profile is only available via the Apple Enterprise program).
Code signing for app and watchOS extensions
Apple Email Signature
Upload an additional provisioning profile for each app extension in your app. Provisioning profiles must be of the same type.
Uploading Signing Files

Make sure the signing assets you upload are those you intend to sign the app with. The bundle identifier and team ID in your app will be overwritten by the signing assets.
To sign your iOS builds, upload a provisioning profile (.mobileprovision) and your certificate (.p12 file) when configuring the build, along with the password you've set for the certificate. These files can be found in the Apple Developer Center, under Certificates, IDs & Profiles.
Finding provisioning profiles
![Apple signature release Apple signature release](https://cnet4.cbsistatic.com/img/-RCJscolYqyd-npeF46YvPMpdEI=/1600x900/2018/12/18/5fdd01fa-a488-4db5-b51c-460249e8287f/ces-show-floor.jpg)
Signature Release Meaning
Option 1 - Getting a provisioning profile (.mobileprovision) from Apple Developer Center
- On the Certificates, IDs & Profiles page, click on Provisioning Profiles.
- Pick the provisioning profile for signing your app in App Center and download it. Make sure to select the right type of profile (development or distribution).
- After saving the provisioning profile locally (in a .mobileprovision file), you can upload it to App Center when configuring a branch.
Option 2 - Getting a provisioning profile (.mobileprovision) automatically generated by Xcode
Note
When Automatically manage signing is enabled in the target of your project, it's possible to upload the developer provisioning profile generated by Xcode instead of one from the Apple Developer Portal. Adding new devices to the Xcode managed profile requires physically connecting the device to your Xcode machine, so this option prevents App Center from registering devices and resigning apps for you.
- Enable the automatic signing option in Xcode. Refer to setting up Xcode to automatically manage your provisioning profiles
- Push the project's changes into your repository.
- Get the generated provisioning profile from
~/Library/MobileDevice/Provisioning Profiles/
- Upload the new provisioning profile Xcode has generated to App Center when configuring a branch.
Getting a certificate from Apple Developer Center (.p12)
- On the Certificates, IDs & Profile page, click on Certificates.
- Select the certificate to be used for signing your app in App Center and download it. Make sure to select the right type of certificate (development or production) and that the provisioning profile you've previously selected contains this certificate.Also, you need to have the private key for the certificate installed on your Mac - it isn't included if you just download the certificate from the Apple Developer Center, you must open the downloaded certificate.
- After you've downloaded the certificate, locate it on your Mac and open it. This will open the 'Keychain Access' app.
- If the correct certificate isn't selected in 'Keychain Access', select 'My Certificates' on the left, and locate the certificate you've downloaded.
- Expand the certificate to see the corresponding private key.
- Select the certificate and private key, then right-click for the context menu on the items and choose 'Export 2 items…'.
- Pick a location on disk to save the file as a
.p12
– it's recommended to use a strong password for the file. - After exporting the provisioning profile locally, you can upload it to App Center when configuring a branch.
