Flutter & Firebase - iOS 오류

Android 보다 iOS 문제가 쉽게 잡히지 않는다. ㅂㄷㅂㄷ

플랫폼이 특정되지 않다며 Podfile Syntax Reference를 참고하라고 한다.

Podfile 수정

ios > Podfile

# Uncomment this line to define a global platform for your project
# platform :ios, '9.0' # 기존 설정
platform :ios, '10.0' # 주석 제거 후 10.0으로 변경

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

project 'Runner', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
}

pod install

$ cd [PROJECT_PATH]/ios # 프로젝트 내 ios 경로로 이동
$ pod install

참고로 9.0으로 설정하고 pod install 하면 아래와 같은 오류가 발생한다. 그래서 10으로 설정하고 진행하니 꽤 오랜 시간이 걸려서 업데이트를 완료했다.

10.0으로 진행한 결과이다.

Pod installation complete! There are 5 dependencies from the Podfile and 22 total pods installed.

[!] CocoaPods did not set the base configuration of your project because your project already has a custom config set. In order for CocoaPods integration to work at all, please either set the base configurations of the target `Runner` to `Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig` or include the `Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig` in your build configuration (`Flutter/Release.xcconfig`).

또 뭔가를 하라고 한다.

Target Support 설정 추가

ios > Fluuter > Release.xcconfig / Debug.xcconfig

#include "Pods/Target Support Files/Pods-Runner/Pods-Runner.release.xcconfig"
#include "Generated.xcconfig"

이렇게 해도 해결되지 않았다. 그래서 계속 찾아서 xcode를 열었다.

Open > [PROJECT_PATH]/ios

ios 폴더를 열어서 Product > Clean Build Folder를 실행한 뒤 Product > Build를 실행해준다.

이렇게 해고 나니 iOS Simulator에서 내 프로젝트 앱을 확인할 수 있었다! 하아...

다른 앱 사용 시 설정

macOS

macOS의 Flutter는 완전히 샌드박스 처리된 애플리케이션을 빌드합니다. 이 애플리케이션은 Firebase 서버와 통신하기 위해 네트워크를 사용하여 통합되므로 네트워크 클라이언트 권한으로 애플리케이션을 구성해야 합니다.
