Common iOS issues
How to overcome common issues building iOS mobile apps on Codemagic
Error creating authentication sessions
When App Store Connect is not correctly set up, users might encounter an error message similar to the following:
altool[xxx:xxx] *** Error: Unable to validate archive '/Users/builder/ipas/xxx'. altool[xxx:xxx] *** Error: code -22020 (Unable to validate your application. We are unable to create an authentication session.)
The most common reason for this error message is using your Apple ID password instead of app-specific password in App Store Connect publishing settings.
To generate an app-specific password, sign in to your Apple ID account page, navigate to the Security section, and click Generate Password… below App-Specific Passwords. The generated app-specific password will be in this format:
abcd-efgh-ijkl-mnop. Insert this value into the Flutter workflow editor or as a password in
codemagic.yaml when setting up publishing to App Store Connect. Note that the password should be generated with the same Apple account that you are using for publishing.
Errors with code signing
This is the list of the most common issues that may cause iOS code signing errors during a CI build.
The uploaded certificate is in a wrong format or corrupt
Codemagic looks for a certificate in Personal Information Exchange (
.p12) format. See how to export the certificate.
The uploaded certificate and provisioning profile do not match
For example, you’re using a development certificate with a distribution profile to sign the build, or the certificate used for signing is not included in the provisioning profile.
Make sure the certificate and the provisioning profile types match.
Missing entitlements in the Apple Developer portal
If you are missing the required entitlements for your app in the Apple Developer portal, you may see error messages such as:
> Code Signing Error: "Runner" requires a provisioning profile with the Push Notifications feature. Select a provisioning profile in the Signing & Capabilities editor.
Check your app’s entitlements by going to Apple Developer portal > Certificates, identifier & profiles > Identifiers > App ID.
iOS scheme not specified for the
archive action of an Xcode build
This applies when your app has custom iOS schemes. By default, Codemagic builds the
Runner scheme, but you can use the
CM_FLUTTER_SCHEME environment variable to specify another scheme.
Bundle ID mismatch
Make sure that the bundle ID entered in automatic code signing setup on Codemagic matches the bundle ID in the build configuration that is used for archiving the app with Xcode.
Codemagic assigns provisioning profiles to build targets and configurations before building the iOS app. That assignment is based on the bundle ID match in both provisioning profile and the build configuration. If a signing configuration is not assigned to the build target/configuration that is used for archiving, the build will fail.
If bundle identifiers are not properly set for your project, you will often see an error message similar to this one:
❌ error: Runner has conflicting provisioning settings. Runner is automatically signed, but code signing identity Apple Push Services has been manually specified. Set the code signing identity value to “iPhone Developer” in the build settings editor, or switch to manual signing in the Signing & Capabilities editor. (in target ‘Runner’ from project ‘Runner’)
- Confirm that you have set the correct bundle identifiers for all targets in Xcode.
- Verify that the bundle identifier set in Xcode matches the bundle identifier set in the Flutter workflow editor under code signing.
Outdated Provisioning profile that does not include Associated Domains.
In such cases, you will often see an error message similar to this one:
❌ error: Provisioning profile "CodeMagic" doesn't support the Associated Domains capability. (in target 'Runner' from project 'Runner'). ❌ error: Provisioning profile "CodeMagic" doesn't include the com.apple.developer.associated-domains entitlement. (in target 'Runner' from project 'Runner').
Log in to your Apple Developer account and verify:
- That you are using the correct bundle identifier.
- If missing, add the Associated Domain Entitlement from there.
- Update the provisioning profile and use it to configure your project.
iOS deployment target issue
A common error message with regard to deployment target is the following:
The iOS deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 14.4.99
The error usually occurs if the deployment target set in Podfile is lower than required or when the Podfile is missing.
- Confirm if a Podfile exists in the repository. If not, create a Podfile in the
iosdirectory and insert the following manually in there:
# Uncomment the next line to define a global platform for your project platform :ios, ’10.0’ target 'Runner' do # Comment the next line if you don't want to use dynamic frameworks use_frameworks! # Pods for Runner end
- Check the Podfile and make sure that
platform :ios, ’10.0’is set to
10.0or above as required by dependencies.
- Confirm if
IPHONEOS_DEPLOYMENT_TARGETis set to 9.0 or above
Build hangs at
Xcode build done
When building for iOS, the build gets stuck after showing
Xcode build done in the log but does not finish and eventually times out.
Log output look similar to this example
== Building for iOS == == /usr/local/bin/flutter build ios --release --no-codesign == Warning: Building for device with code signing disabled. You will have to manually codesign before deploying to device. Building net.butterflyapp.trainer for device (ios-release)... Running pod install... 3.7s Running Xcode build... Xcode build done. 203.6s
This is a known issue that occurs randomly and can be traced back to Flutter:

Mac M1 issues
Builds not starting
Builds not starting at all even though the team has access to
This error occurs on M1 machines when the
xcode property is not set to version 13.x. Please configure your workflow to use Xcode version 13 or above.
Builds failing intermittently
Builds are intermittently failing without a clear reason.
This issue can be caused by an earlier version of Xcode. Please use version
13.4.1 or newer, if possible.
Error when using an adhoc profile
When building iOS apps with an adhoc profile you might get this error:
error: Provisioning profile "XXXX" doesn't include the currently selected device "builder's Virtual Machine" (identifier XXXXXXXX-XXXXXXXXXXXXXXXX). (in target 'XXXXXXX' from project 'App').
Add the following to the end of your
xcode-project build-ipa command:
XCode 14 known issues
Error (Xcode): Signing for “XXX” requires a development team. Select a development team in the Signing & Capabilities editor
This issue has been fixed on the stable channel in Flutter 3.3.3.
However, if you would like to continue previous versions of Flutter you can open
ios/Podfile and add the following at the end of it:
post_install do |installer| installer.pods_project.targets.each do |target| flutter_additional_macos_build_settings(target) target_is_resource_bundle = target.respond_to?(:product_type) && target.product_type == 'com.apple.product-type.bundle' target.build_configurations.each do |build_configuration| if target_is_resource_bundle build_configuration.build_settings['CODE_SIGNING_ALLOWED'] = 'NO' build_configuration.build_settings['CODE_SIGNING_REQUIRED'] = 'NO' build_configuration.build_settings['CODE_SIGNING_IDENTITY'] = '-' build_configuration.build_settings['EXPANDED_CODE_SIGN_IDENTITY'] = '-' end end end end
In XCode 13
CODE_SIGNING_ALLOWED was set to
NO by default for resource bundles. While in Xcode 14 they changed this to default to
YES, which might be causing the problems.
