This looks like critical issue as Cocoapods method crashes and also blocks issue triage

Hmm, I just tried it from flutter master and it worked
Can you run
Product > Clean Build Folderfrom Xcode, run on the physical device again, then export the full build logs?TahaTesser commentedon Aug 26, 2021
@jmagman
Thanks for taking a look at this, just tried on my home MBP, same results.

I also tried it again on another machine and it worked...
Are you hitting #88407? What's the output of
ls -la path/to/flutter/bin/cache/artifacts/engine/ios/Flutter.xcframework?TahaTesser commentedon Aug 27, 2021
@jmagman
Here is the result
Compared to #88407 (comment), looks like I have
ios-arm64_armv7instead ofios-armv7_arm64TahaTesser commentedon Aug 27, 2021
I tried following the instructions to delete
rm -rf path/to/flutter/sdk/bin/cache/artifacts/engine/ios*on the latestmasterchannel but app still freezes .flutter run -vstill generatesarm64_armv7Logs

Verified this on latest master and stable and I was unable to replicate on master wherein, the
FlutterViewControllerlaunches properly on iOS simulator (14.3) and on iPhone 6s (14.4.1) device as below:88968.mov
RPReplay-Final1630058899.MP4
On stable though, it runs properly on simulator, but on device, gets stuck while trying to launch
FlutterViewControlleras below:RPReplay-Final1630059350.MP4
stable and master flutter doctor -v
Keeping this open for further insights, as Taha seems to be consistently experiencing this issue on master and on two different machines.

What is the output of

@darshankawar I tried this again on stable on a real device and again it ran fine. Are you hitting #88407? What is the output of
ls -la flutter_module/.ios/Flutter/engine/Flutter.xcframework?darshankawar commentedon Aug 30, 2021
@jmagman No. I think the linked issue is about blank screen upon launch on stable, but in my case, it loads the initial screen but then trying to tap on
launch FlutterViewControllerdoesn't take me to next screen.Output of

I'm also unable to run this sample for triage, which also uses cocoapods method

jmagman commentedon Sep 7, 2021
@darshankawar you did indeed hit #88407, you have both
ios-arm64_x86_64-simulatorandios-x86_64-simulator,ios-arm64_armv7andios-armv7_arm64.Delete the cached engine, then
flutter cleanfrom the module. Are you then able to launch the app?@TahaTesser seems to be hitting something else though...
darshankawar commentedon Sep 8, 2021
@jmagman Hi, ok, I see.
With this, yes, I was able to go past the initial screen properly on stable now, as below:

Earlier, it used to get stuck after tapping on

Tried it again today out of curiosity, the issue is somehow fixed itself, I can't reproduce it anymore.
Closing this for now, if it resurface, I will comment
