Steps to reproduce:
cd ~
mkdir pubios
cd pubios
flutter create --template module my_flutter
open xcode and create new project - Single View App (Storyboard based)
I call it host_ios
so file structure currently is next
pubios/
├─my_flutter
└─host_ios
generating flutter app frameworks (note: directly to host_ios folder)
cd my_flutter
flutter build ios-framework --output=../host_ios/embed/
Go to xcode and DO steps described in documentation Option B - Embed frameworks in Xcode
- Go to settings -> General tab
- Press app/plus button in section Frameworks, Libraries, and Embedded Content
- Press buttun Add Other... -> Add Files
- Navigate to folder
../host_ios/embed/Release/where frameworks saved - Select both App.framework and Flutter.Framework
- open Build Settings tab and search for Framework Search Paths (FRAMEWORK_SEARCH_PATHS)
- change hardcoded value from
$(PROJECT_DIR)/embed/Releaseto$(PROJECT_DIR)/embed/$(CONFIGURATION) - open file
../host_ios/host_ios.xcodeproj/project.pbxprojin some text editing tool - replace row
path = embed/Release/App.framework;topath = "embed/$(CONFIGURATION)/App.framework"; - do same for Flutter.Framework
- save, exit ang go to xcode (your frameworks icons now has some white color in settings)
Open ViewController.swift and replace content with this code
import UIKit
import Flutter
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let button = UIButton(frame: CGRect(x: 140, y: 200, width: 100, height: 50))
button.setTitle("run flutter", for: .normal)
button.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)
self.view.addSubview(button)
}
lazy var flutterEngine = FlutterEngine(name: "flutter engine for reports")
var flutterVC:FlutterViewController? = nil
@objc func buttonAction(sender: UIButton!) {
if flutterVC == nil{
// Runs the default Dart entrypoint with a default Flutter route.
// flutterEngine field initialized lazily
flutterEngine.run();
flutterVC = FlutterViewController(engine: flutterEngine, nibName: nil, bundle: nil)
}
present(flutterVC!, animated: true, completion: nil)
}
}
Run and you should see the integrated to the host ios app default flutter counter app presented after button tap.
Now, lets try to upload this app to appstore connect!
Follow the documentation tutorial Build and release an iOS app
- I change BundleIdentivier, Version, Build number in General tab
- And change Signing section in Signing&Capabilities tab to appropriate values (Distribution provisionProfile and Distribution certificate)
Next, archive and upload product to appStore connect!
Code signing "Flutter.framework" failed.
Ps
My code signing entitlements is correct. Because if I remove added frameworks I can successfully sign and upload the app to appstore connect.
In Distribution logs I cant find anything that describe error more detailed. All files attached
