Firebase 10 is bumping the minimum supported versions for iOS, tvOS, and macOS.

The below table summarizes the key differences in the minimum supported versions between Firebase 9 (current) and Firebase 10 (upcoming):

Platform	Firebase 9	Firebase 10
iOS	10.0	11.0*
macOS	10.12	10.13
tvOS	10.0	11.0

*Analytics will remain at 10.0. This is reflected by Analytics's dependencies.

Bumping iOS versions

The minimum iOS version is specified using the following pattern:

ios_deployment_target = '10.0'
s.ios.deployment_target = ios_deployment_target

Find and replace script

git grep --name-only "ios_deployment_target = '10.0'" -- \
  ':!FirebaseCore*.podspec' \
  ':!FirebaseInstallations.podspec' \
  ':!FirebaseAnalytics*.podspec' \
  ':!GoogleAppMeasurement*.podspec' \
  *.podspec \
  | xargs sed -i '' "s/ios_deployment_target = '10.0'/ios_deployment_target = '11.0'/g"

FirebaseCore* and Installations are excluded as they are dependencies of Analytics which is not bumping it's iOS minimum version.

s.ios.deployment_target = '9.0'

Find and replace script

git grep --name-only \
  -E "ios\.deployment_target(\s+)=(\s+)'10.0'" -- \
  ':!FirebaseCore*.podspec' \
  ':!FirebaseInstallations.podspec' \
  ':!FirebaseAnalytics*.podspec' \
  ':!GoogleAppMeasurement*.podspec' \
  ':!Firebase.podspec' \
  *.podspec | xargs sed -i '' -E "s/ios\.deployment_target( +)=( +)'10.0'/ios\.deployment_target\1=\2'11.0'/g"

FirebaseCore* and Installations are excluded as they are dependencies of Analytics which is not bumping it's iOS minimum version.

Additionally, the Firebase.podspec is excluded as it needs to manually be modified.

Bumping macOS versions

git grep --name-only "'10.12'" *.podspec | xargs sed -i '' "s/'10.12'/'10.13'/g"

Bumping tvOS versions

The minimum tvOS version is specified using the following pattern:

tvos_deployment_target = '10.0'
s.tvos.deployment_target = tvos_deployment_target

Find and replace script

git grep --name-only "tvos_deployment_target = '10.0'" -- \
  *.podspec \
  | xargs sed -i '' "s/tvos_deployment_target = '10.0'/tvos_deployment_target = '11.0'/g"

s.tvos.deployment_target = '9.0'

Find and replace script

git grep --name-only \
  -E "tvos\.deployment_target(\s+)=(\s+)'10.0'" -- \
  *.podspec | xargs sed -i '' -E "s/tvos\.deployment_target( +)=( +)'10.0'/tvos\.deployment_target\1=\2'11.0'/g"

@paulb777, CI has lots of failures but they look like network issues. Maybe the CocoaPods CDN is down right now...

I will kick off another CI run in an hour or two

Sep 20 '22 16:09 ncooke3

The Auth failure was due to the FBSDK being updated due to raising the min. supported OS versions. This enabled the Auth sample to pull in FBSDK 13+ (opposed to FBSDK 12). And, in FBSDK 13+, there were breaking changes that broke the Auth sample app.

Sep 21 '22 19:09 ncooke3

@paulb777, CI in ce29315 was green except for the Auth x FBSDK issue.

I think this is good for a review now that CI should be all fixed.

The new commit to fix the FBSDK stuff did unfortunately kick off all CI but hopefully we do not see those 429 errors again 🤞

I'm going to merge because all of the tests but one passed in ce29315. And the failing test was resolved with 4ac4677.
