I want to test a release build of my Flutter 1.9 iOS app on my iPhone without going through the App Store. The development build from IntelliJ runs just fine on my iPhone, but I want to see the real performance characteristics.
The Flutter documentation describes how to build a release version of the app. This creates build/ios/iphoneos/Runner.app in my project. But how can I get Runner.app from my Mac onto my iPhone?
With flutter run --release -d [device name], you can run the Flutter app in release mode either in a simulator or on a real device. Thank you, Chenna Reddy!

So i'm testing a flutter app that builds and installs successfully on an iOS simulator as well as a physical devices. However, when building and installing the app with xcode via the USB, it successfully installs and launches but when the USB is disconnected from my mac and i try to run the already installed device on the iPhone, it shows only the launch / splash screen and fades and closes.
Is there something i'm doing wrong that causes this to happen? As the app works fine when connected with the USB and it's being run.
If the build is in debug mode - it won't open.
if you want to open application after disconnecting, try profile / release mode
flutter run --profile
or
flutter run --release
In iOS, debug build doesn't work without USB. To use the app without USB trying making a release build using flutter run --release
issue in old build
i have build my flutter ios build with Debug so it will crash on ios 14 new major release
Change Debug to release in Build, Run, Test, Analyze from Edit Scheme
Due to low-level changes in iOS’s debugger mechanisms, developers using versions of Flutter earlier than 1.20.4 stable won’t be able to launch apps (by using flutter run or a Flutter-enabled IDE) on physical iOS devices running iOS 14. This affects debug, profile, and release builds. Simulator builds, add-to-app modules, and running directly from Xcode are unaffected.
Upgrading to Flutter 1.22 beta allows you to build, test, and deploy to iOS without issue. Upgrading to 1.20.4 stable allows you to build and deploy to iOS 14, but not debug.
I am getting this error when using titanium and trying to run my app on iOS simulator . I could do it before. My SDK version is 7.5.0.GA. How can I make it fine?
I use the command below to build my app:
ti build -p ios -T simulator
7.5.0.GA is from 2018. I strongly recommend updating the SDK to the latest (currently 9.0.3.GA) to make your app work again with the latest simulators and be able to push it to the app store. Check:
https://wiki.appcelerator.org/display/guides2/Titanium+Compatibility+Matrix#TitaniumCompatibilityMatrix-iOS
for a compatibility chart
Here's my Environment
Xcode Version: 11.1 (11A1027)
Physical device: - iPad mini 2 (IOS 12.4.2)
VSCode Version: 1.39.2
Flutter version: 1.9.1+hotfix.6
When I use the iOS part of the Flutter project and run it physical device using XCode, it detects the device and works fine but I am somehow not able to see the device on the available devices section on VSCode.
However VSCode detects and works fine with the simulator.
I also ran flutter doctor to see connected devices, but again it does not show the connected physical devices but shows the simulator created device.
Use rm -rf <flutter_repo_directory>/bin/cache to force delete the files in cache and then flutter doctor -v to reinstall the missing sdk directories.
Deleting the cache in flutter/bin/cache directory and then reinstalling the dart sdk solved this issue.
Referred to this issue in Flutter repository(Issue No:41006).
I had the same issue. In my case, a recent iOS update had turned off Developer mode, for some reason... So I needed to enable it again (Settings - Privacy & Security - Developer Mode).
iPadOS / iOS Devices Setup for Hot Reload
Before trying to flutter Debug on physical device from Vscode it is Required to first :
Run a successful Xcode build on that iOS or iPadOS device
Follow this steps if you don't know how to Run Xcode Build -> your device should then be detected by flutter :
Open Xcode & do all the classic Set Up (Signing in with a Team & choosing a UNIQUE bundle Identifier)
Set Your iPhone Auto-Lock to Never (& Unlock it !) - Connect your iPhone or iPad to Mac with USB cable & Accept Prompt on the iPhone
Run Xcode Build on your iPhone this alert prompt will select Ok
On your iPhone a new menu will have appeared - Navigate to it & Click « Verify App » or « Accept »
Now Run Xcode Build Again - if does not run try running flutter clean & flutter build ios & try running again
—
After Successful Xcode Build - Stop Running the App
Keep Xcode Open
— iOS Setup is done
Close all Simulators or Emulators - Close VsCode
run flutter devices to make sure your Device is now detected
if it’s not try Turning it off & plugging it back again - remember to accept Trust Computer Prompt - keep it device unlocked too !
Open back your project in VsCode or Android Studio
Hot Reload⚡️Using VsCode :
Press F8 or Select ▷ « Start Debugging » in main.dart
That’s it ! You now have the power of Hot Reload⚡️ with VsCode on a physical device !
Hot Reload using Terminal Commands :
run flutter run -d yourDeviceID
Have fun ! Press r in Terminal for HotReload⚡️
If you need to find your iOS device ID :
Select Add Additional Simulators
Hot Reload⚡️on Android Studio :
Select your device & run
All I had to do was to disconnect the device from the laptop, make sure VS Code is open, then connect the device again while no VS Code, then it detected right away and chose the device automatically.
Sometimes it doesn't detect the device if it is not directly connected to the computer. I had a docking station in between and it didn't recognized the device. Especially after you have updated you macOS just before.
With "focus mode" activated on the device (like "do not disturb" 🌙) it won't show up.
Check whether you have fully installed xcode by running flutter doctor -v
Incase you find that some thing like
[!] Xcode - develop for iOS and macOS
✗ Xcode installation is incomplete; a full installation is necessary for iOS development.
Download at: https://developer.apple.com/xcode/download/
Or install Xcode via the App Store.
just run install Xcode and run
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
sudo xcodebuild -runFirstLaunch
Incase you installed xcode already, just run the above commands, they will do the magic.
I want to test the release build version on my iOS device directly using this command:
cordova run --buildConfig=build.json ios --release --device
But not working, is anybody here manage to test the release build version running on device? Thanks in advance.
Or let say the worst case, we can't do it. Is there any guarantee that below command:
cordova build --buildConfig=build.json ios --release
will build the release version of our app, when we open the xcode project on xcode?
My point is I need to get the release version build by cordova, not by Xcode.
Likely not guaranteed, but that's just a guess.
I'm not sure why you need Cordova to put together a release build—in order to submit to the app store you will want to use Xcode to archive your app. I have no idea if Cordova can do a proper archive but personally I wouldn't rely on it because at least Xcode should be up to date on what Apple demands from the build. Especially with automatic code signing. Cordova may lag in its implementation when Apple changes things.
One little thing, when a .ipa is signed for distribution through the app store, you cannot side load it onto a device. You can only side load .ipas that are signed for development.
