Failed to install the requested application - Flutter

Question

I am facing an issue with launching my flutter app in the Xcode simulator. the android version of the app is working fine while testing with an android emulator, not getting any errors, even while successfully building the app, but I don't know what's going wrong with the Xcode. (IOS version)

flutter version: v2.5.3 | devtools: v2.8.0

Error log: (flutter run)

Unable to install /Users/USER_NAME/Documents/APP_NAME/main_files/source/wordpress_app/build/ios/iphonesimulator/Runner.app on FEBE8117-5EC5-429F-820D-DA1F80359C7B. This is sometimes caused by a
malformed plist file:
ProcessException: Process exited abnormally:
An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=22):
Failed to install the requested application
The bundle identifier of the application could not be determined.
Ensure that the application's Info.plist contains a value for CFBundleIdentifier.
  Command: /usr/bin/arch -arm64e xcrun simctl install FEBE8117-5EC5-429F-820D-DA1F80359C7B
  /Users/USER_NAME/Documents/APP_NAME/main_files/source/wordpress_app/build/ios/iphonesimulator/Runner.app
Error launching application on iPhone 11.

I appreciate any help you can provide.

Solution 1

The error is happening because your bundle identifier (CFBundleIdentifier) is not correct. com.MY_NAME.MY_APP_NAME is not an environment variable, and therefore cannot be evaluated using $().

In flutter the CFBundleIdentifier should be set to the value of PRODUCT_BUNDLE_IDENTIFIER which is an environment variable defined in ios\Runner.xcodeproj\project.pbxproj.

So, in your Info.plist file, replace:

<key>CFBundleIdentifier</key>
<string>$(com.MY_NAME.MY_APP_NAME)</string>

With:

<key>CFBundleIdentifier</key>
<string>$(PRODUCT_BUNDLE_IDENTIFIER)</string>

Solution 2

This can sometimes be caused when you have not added your GoogleService-Info file

The error suggests there is an issue with your Info.plist file. Can you share what your Info.plist file looks like?

sure, here is it: pastebin.com/pVhNRn8h

[mmcdon20]

Don't try to hard code your CFBundleIdentifier, try using this <key>CFBundleIdentifier</key><string>$(PRODUCT_BUNDLE_IDENTI‌​FIER)</string>

Dear, Don't I have to replace CFBundleIdentifier value with my iOS package name?

[mmcdon20]

PRODUCT_BUNDLE_IDENTIFIER should be set to your iOS package name. Don't set the CFBundleIdentifier manually in your Info.plist file.

Man!!!! You are the god! It fixed my issue. WOW. Thanks a lot. Would you please post it as an answer so I can select it as the correct answer? It will help other people.

My CFBundleVersion looks like this: imgur.com/ZD5YC8H

[Demoxing]

So, I replace CFBundleVersion value with $(FLUTTER_BUILD_NUMBER)?
