[cloud_firestore] Xcode build extremely slow

EDIT (@Salakar): See #2751 for a solution.

Summary of Issue

Simply adding cloud_firestore to pubspec.yaml results in a huge increase in iOS xcode build times. The issue can be recreate with nothing more than a simple flutter create application and minor changes to pubspec.yaml.

MacOS Mojave 10.14.6
Xcode 10.3

> flutter --version
Flutter 1.8.4-pre.91 • channel master • https://github.com/flutter/flutter.git
Framework • revision 8fdd759225 (11 hours ago) • 2019-08-04 00:56:23 -0400
Engine • revision c8f4f5d5cc
Tools • Dart 2.5.0 (build 2.5.0-dev.1.0 9bb446aae1)

> flutter create test_cloud_firestore
> cd test_cloud_firestore

Without cloud_firestore

Just to show that it is specifically the cloud_firestore plugin that causes this issue I will add some other firebase plugins to pubspec.yaml:

firebase_core: ^0.4.0+1
firebase_analytics: ^4.0.2

Now we build the app:

> flutter packages get
> time flutter build ios
....
Xcode build done. 
real	0m41.014s

Okay that looks reasonable.

With cloud_firestore

Simply add the latest version of cloud_firestore plugin to pubspec.yaml (no other changes):

cloud_firestore: ^0.12.9

Now we build the application again:

> flutter packages get
> time flutter build ios
....
Xcode build done. 
real	6m40.982s

Yes... that is right. A six minute increase in iOS build times just from adding the cloud_firestore plugin to pubspec.yaml. Again, no changes were made to the flutter create generated application, this is simply changes to pubspec.yaml.

Logs

I did confirm that this issue persists on other flutter channels as well as other later versions of cloud_firestore plugin.

@walsha2

The issue at flutter/flutter#37582 has been closed and moved here. Future collaboration on this issue will be done here.

[walsha2]

@kroikie Ok. So does this new issue lose all the traction of flutter/flutter#37582 in terms of user reaction and up votes. From what I gather, that is what determines what gets worked on in the priority queue.

I just want this "new" issue to have the same level of priority as the previous one did, which seemed to be a concern that was pretty widespread in the community.

[kroikie]

@walsha2 no we will still refer to the linked issue for reference during triage. The goal is to collect all future FlutterFire collaboration in a single place.

[rdmo94]

@kroikie Still no solution for this? I have been struggling with this issue for days...

[kbrmimbyl]

Not sure if others have noticed: this whole "extremely slow" issue didn't exist in Flutter 1.0.0.

[rdmo94]

Update: Building my application in an iOS Simulator is still very slow (sometimes above 500 seconds) and the problem seems to arise when using cloud_firestore plugin. So now i use my device instead. I build it through Xcode and attach flutter afterwards with "flutter attach -d device name" in terminal.

I also encounter this problem on i7 MacBook Pro. Adding cloud_firestore increased my build time to simulator from 1-2 minutes (60-120 sec) to more than 7-10 minutes and release build on CI to over 15-20 minutes.

Sample output from deploying to simulator:

Launching lib/main_dev.dart on iPhone 11 in debug mode...
Xcode build done.                                           458,6s

This was not clean build but some changes to dart code have been made. Previous clean build with pod install took over 600 sec.

Edit: switching to current master dropped this number to about 250-270 sec on a clean build!

Due to this problem I'm no longer developing on Mac even for iOS. I do most of the development on Ubuntu Linux using an Android emulator and then switch to Mac to run the same code on the iOS emulator. Very painful... but running on Mac isn't an option.

Same here, I started considering buying new machine...but i see that thats not really the case. Any workaround ? is there any chance to include firestore as pre-compiled binary ?

Here is my flutter doctor and pubspec if its useful, the same issue is happening to me. Very slow to build on iOS

Can confirm the super ugly build times with Firestore too. Sometimes getting like peak 230 seconds on a quite fast Macbook Pro. This is really barely usable at this point. Unfortunately we need Firestore.

This was my latest build
