Swift Compiler Error (XCode) breaking build #2050

Closed aardrop closed 2 years ago

aardrop commented 2 years ago

Description

Something in the swift files is causing XCode to throw this error:

Swift Compiler Error (Xcode): 'let' property 'convert' may not be initialized directly; use "self.init(...)" or "self = ..." instead
/<App Directory>/ios/Pods/Amplify/Amplify/Categories/DataStore/Model/Temporal/SpecBasedDateConverting.swift:22:13

I've cleaned everything and re-installed and updated pods many times at the point and nothing seems to work. Does anyone have any idea how to fix this?

Hello @arkeri this issue seems to be related to https://github.com/aws-amplify/amplify-ios/issues/2001

Can you paste the content of the Podfile under the ios directory of your Flutter project?

aardrop commented 2 years ago

Here is the contents of my podfile:

# Uncomment this line to define a global platform for your project
platform :ios, '14.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

use_frameworks!

project 'Runner', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
}

def flutter_root
  generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
  unless File.exist?(generated_xcode_build_settings_path)
    raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end

require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)

flutter_ios_podfile_setup

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '14.0'
      config.build_settings['ONLY_ACTIVE_ARCH'] = 'NO'
      config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES'
      config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
    end
  end
  installer.pods_project.build_configurations.each do |config|
    config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
  end
end

Hello @arkeri this issue seems to be related to aws-amplify/amplify-ios#2001

Can you paste the content of the Podfile under the ios directory of your Flutter project?

Following the discussion here, it allows us to run builds by changing ['BUILD_LIBRARY_FOR_DISTRIBUTION'] to 'NO', but it seems to be messing with our deployment pipeline. Is there a reason this is necessary, considering that for us, until yesterday Amplify didn't require this change?

fjnoyp commented 2 years ago

Hi @arkeri did the build suddenly break or did you update xcode/amplify flutter dependencies beforehand?

I believe the reasons for that requirement are contained within the linked amplify ios issue:

aardrop commented 2 years ago

@fjnoyp, No, for the past two months we had not had this issue at all with the same most recent version of flutter and the same version of amplify. My hypothesis is that a stable version of Amplify or a dependency of amplify was stored in DerivedData for a while after this issue first started so when that cleared it caused this issue to come to light from the new code but for us, it arrived out of nowhere.

Jordan-Nelson commented 2 years ago

Hi @arkeri - It is possible that something changed that is causing this to no longer be supported, but I don't believe it ever was intended to be supported in the first place. Is there a specific reason that you have set this in your Podfile? If there is a good use case for this, we can bring it to the Amplify-iOS team to be considered. Otherwise, the recommended fix is to remove this from the Podfile.

Jordan-Nelson commented 2 years ago

Hi @arkeri - I am going to close this out since there is a recommended fix for this. If you believe there is a good use case to support this, please open a new request. Thanks.
