Troubleshooting

Installing & Building Errors​

No such module 'LMGUI' when compiling​

Caused by issues with M1 Mac + some versions of CocoaPods. To fix, explicitly set ONLY_ACTIVE_ARCH to NO for all pod targets.

In your Podfile, add a post_install method like so:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      # Fixes build issues with Pods on M1 Macs
      config.build_settings['ONLY_ACTIVE_ARCH'] = 'NO'
    end
  end
end

See the StackOverflow discussion of the same issue with 32 vs 64 bit architectures for more details.

File not found: libarclite_iphonesimulator.a when compiling​

Affects: Xcode 13+

Full error message: File not found: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/arc/libarclite_iphonesimulator.a

Some bundled dependencies have a deployment target that is lower than the minimum supported target of newer Xcode versions. To fix, either update or remove the deployment target configured in the Podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      # EITHER
      # Set all Pod deployment targets to a specific minimum version
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
      
      # OR
      # Delete the setting to use the project default for all pods
      config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
    end
  end
end

Runtime Errors​

Request can't be completed error when resuming app​

This is generally caused when Background Fetch is not enabled, and the app is sent to the background while a network request is pending.

See Quickstart: Additional Configuration for more details.
