 ### IMPORTANT Note for iOS
-To be able to use this plugin on iOS, you need to create the Flutter App with `flutter create -i swift` (see [flutter/flutter#13422 (comment)](https://github.com/flutter/flutter/issues/13422#issuecomment-392133780)), otherwise, you will get this message:
+If you are starting a new fresh app, you need to create the Flutter App with `flutter create -i swift` (see [flutter/flutter#13422 (comment)](https://github.com/flutter/flutter/issues/13422#issuecomment-392133780)), otherwise, you will get this message:
 ```
 === BUILD TARGET flutter_inappbrowser OF PROJECT Pods WITH CONFIGURATION Debug ===
 The “Swift Language Version” (SWIFT_VERSION) build setting must be set to a supported value for targets which use Swift. Supported values are: 3.0, 4.0, 4.2. This setting can be set in the build settings editor.
 ```
-that is not true! The Swift version that I have used is already a supported value: 4.0.
+
+If you still have this problem, try to edit iOS `Podfile` like this (see [#15](https://github.com/pichillilorenzo/flutter_inappbrowser/issues/15)):
+```
+target 'Runner' do
+  use_frameworks!  # required by simple_permission
+  ...
+end
+
+post_install do |installer|
+  installer.pods_project.targets.each do |target|
+    target.build_configurations.each do |config|
+      config.build_settings['SWIFT_VERSION'] = '4.0'  # required by simple_permission
+      config.build_settings['ENABLE_BITCODE'] = 'NO'
+    end
+  end
+end
+```

+Instead, if you have already a non-swift project, you can check this issue to solve the problem: [Friction adding swift plugin to objective-c project](https://github.com/flutter/flutter/issues/16049).
