Compiling for iOS 10.0, but module 'GRDB' has a minimum deployment target of iOS 11.0

[ksemianov]

After the recent increase in the iOS deployment target of GRDB.swift, RxGRDB doesn't compile

Compiling for iOS 10.0, but module 'GRDB' has a minimum deployment target of iOS 11.0

Probably, the deployment target for RxGRDB should be raised as well

GRDB.swift (5.12.0)
RxGRDB (2.0.0)
Xcode 13.0 (13A233)
COCOAPODS: 1.11.2

Hello @ksemianov,

Probably, the deployment target for RxGRDB should be raised as well

This does not make sense: RxGRDB 2.0 declares a dependency on GRDB 5.0+, which targets iOS 10+. There is no reason RxGRDB 2.0 could not work with GRDB 5.12+ and iOS 11+.

To me, the "Compiling for iOS 10.0" message tells that your app is requiring iOS 10.0, and this is where you should act.
Did you check your IPHONEOS_DEPLOYMENT_TARGET? Did you check if your Podfile mentions platform :ios, '11.0'?

[ksemianov]

IPHONEOS_DEPLOYMENT_TARGET is set to 11.0
Podfile contains line platform :ios, '11.0'

The latest GRDB.swift (5.12.0) targets iOS 11.0. While the latest RxGRDB (2.0.0) targets iOS 10.0. Swift cannot do import GRDB in RxGRDB, because it requires at least 11.0 to do so

Do you need a minimal repro?

This sounds like a bug in CocoaPods to me.

[ksemianov]

Well, it's a limitation of CocoaPods. When Pod author writes s.ios.deployment_target = '10.0' it will translate to compiling with exactly 10.0 iOS SDK when pod install generates .xcworkspace. It doesn't check that RxGRDB dependency has a higher deployment target and set 11.0 instead

Here is an example to reproduce the error https://github.com/ksemianov/RxGRDB.CompilationError

I'd appreciate a link to the issue about this "limitation" in the Cocoapods repo, thank you.

...Or maybe the RxGRDB podspec should be changed in order to specify a minimum iOS version instead of a hard-coded version. But a straight bump is not supposed to be necessary, and I'm pretty sure this annoyance has been discussed at length on the CocoaPods repo. If you don't find those discussions online I will, but your help is appreciated.

[ksemianov]

I think this reply is relevant CocoaPods/CocoaPods#7314 (comment)

There is a workaround to specify the deployment target in Podfile post install hook:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == 'RxGRDB'
      target.build_configurations.each do |config|
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '11.0'
      end
    end
  end
end

Submitted an issue to CocoaPods in case they decide to make an enhancement CocoaPods/CocoaPods#10968

Thanks @ksemianov, I'll do my best shortly, based on your excellent input 👍

It's happening in SPM too, its looks like because the GRDB is already updating its platform from iOS 10 to iOS 11 (starting from 5.12.0), and since RxGRDB is dependent on > 5.0.0, then SPM will get the latest version which already bumped its platform to iOS 11.

One way I do to fix the error is by explicitly add GRDB as project dependency and set its version to exactly 5.11.0 or lower. Then RxGRDB will be forced to use it.

for information, my project is set a minimum target for iOS 11.0, so it does not make sense, but I guess the main problem is not on the Dependency Manager (Cocoapods / SPM) since both are behaving the same.

I guess some of the solutions that can be done on RxGRDB is:

• set the GRDB dependency to be explicit to 5.11.0
• bump the minimum platform to iOS 11.0

Thank @hainayanda. I will shortly ship an RxGRDB version that bumps the minimum iOS version, and fix both CocoaPods and SPM issues. So long 32-bits devices!

Hi @groue! I'm also facing the same issue with min iOS version, any progress on a new version?
Looking forward for your update,
thanks!

🚀 There we go, v2.1.0 has shipped!
