Description

When trying to include RealmSwift into a Flutter Plugin, the example app doesn't start.

The goal is to create a plugin to import data from an existing realm database as we're migrating two native apps (Android and iOS) to Flutter.

Here's the podspec file:

#
# To learn more about a Podspec see http://guides.cocoapods.org/syntax/podspec.html.
# Run `pod lib lint database_importer.podspec` to validate before publishing.
#
Pod::Spec.new do |s|
  s.name             = 'database_importer'
  s.version          = '0.0.1'
  s.summary          = 'A plugin to import previous database versions'
  s.description      = <<-DESC
A plugin to import previous database versions
                       DESC
  s.source           = { :path => '.' }
  s.source_files = 'Classes/**/*'
  s.dependency 'Flutter'
  s.dependency 'RealmSwift'
  s.platform = :ios, '12.0'

  # Flutter.framework does not contain a i386 slice.
  s.pod_target_xcconfig = { 'DEFINES_MODULE' => 'YES', 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'i386' }
  s.swift_version = '5.0'
end
