This solution fixed "Failed to load model" when using iOS device.

• How to use iOS Metal Delegate (GpuDelegate)? am15h/tflite_flutter_plugin#100 (comment)
• https://www.tensorflow.org/lite/guide/build_ios#build_tensorflowlitec_dynamic_framework_recommended

Steps I've done (Make sure you already install brew)

Step 1 :

• Install TensorFlow and here is the link to teach how to install https://www.geeksforgeeks.org/install-tensorflow-on-macos/ (Follow step 1 until step 7)

Step 2 :

• Open your terminal to Install Bazel by typing $brew Install bazel (I'm using version 4.2.2).

Step 3:

• Clone this git clone https://github.com/tensorflow/tensorflow project and place it into this folder pythonenv (Created at step 1).

Step 4 :

• Open terminal cd to the root TensorFlow (Step 3 clone TensorFlow Folder) and type $./configure to run the script. Press enter to use default answer and answer Yes when the script asks if you wish to build TensorFlow with iOS support.

Step 5 :

• Open terminal and type bazel build --config=ios_arm64 -c opt //tensorflow/lite/ios:TensorFlowLiteC_framework & bazel build --config=ios_arm64 -c opt //tensorflow/lite/ios:TensorFlowLiteCMetal_framework.
• It will create 2 zip files which are TensorFlowLiteCMetal_framework.zip & TensorFlowLiteC_framework.zip inside this location user/pythonenv/tensorflow/bazel-bin.

Step 6 :

• Unzip those 2 zip files and place it in your flutter package > iOS folder user/flutter/.pub-cache/hosted/pub.dartlang.org/tflite_flutter-0.9.0/ios (Make sure you use Command+Shift+Dot to show invisible folder).

Step 7 :

• After placed your 2 folders inside this iOS folder and then you need to edit tflite_flutter.podspec (This file is in the same location)

Step 8 :

• Line 20 replace with s.ios.vendored_frameworks = 'TensorFlowLiteC.framework', 'TensorFlowLiteCMetal.framework
• Line 27 replace with s.xcconfig = { 'OTHER_LDFLAGS' => '-framework TensorFlowLiteC -all_load -framework TensorFlowLiteCMetal -all_load' }

Step 9 :

• Go back to your project and in your terminal type flutter clean && flutter pub get && cd ios && pod install && flutter run
