Pressing debug icons on iPhone 11 app will crash

[jerryhamby]

Just updated to iOS 14 and all my Flutter apps on the phone show the icon,
but when pressing the icon the app tries to start, then it just vanishes(crashes).

If I debug from Flutter to the device the app appears fine as long as I'm tethered.
If I disconnect the device from my Mac, the icon has the above problem.

Funny, "Stuck on white screen when debugging iOS (#63800)" seems to be working now.
This must be a Flutter problem, because it also happens when I export to my device from Xcode.
(tested a couple of times)

This crashing happens with all my previously created Flutter apps.

iOS 14
iPhone 11
Flutter 1.20.4 (iMac 10.15.6)

Hello @jerryhamby,
This is a known issue. The support for the iOS 14 is on dev channel now. If you want to switch from Stable to Dev, please run flutter channel dev.

FYI, The code might not be stable, yet.

I've just upgraded my Mac to 10.15.7 and this issue is worst now.

I'm running my app (from VSC) to my physical device (iPhone 11), this use to work as long as I was connected and stayed connected using a wire to my device. Now it goes to a "white screen" and displays the error:
Exited (sigterm)
Could not update files on device: HttpException: , uri = http://localhost:50029

2- If I try to use Xcode to load my app to the device, I now get another error:
Undefined symbol: _SDImageCoderEncodeCompressionQuality

Bottom line, I'm locked out from testing with my physical device, until someone on the Flutter team decides to fix things.
I don't think I'm the only one. I'm in the final stages of testing and this is a SUPER problem in my efforts...

iMac: 10.15.7
Flutter: 1.20.4
VSC: 1.49.2
iPhone 11: 14.0

A note about further testing:

I decided to test on my iPhone 7 device (with older OS) (on VSC) and things worked fine with one big exception.
It still gets the "white screen" for 3-4 minutes before it will load.
Can't test on my iPhone 11 device, but I can now with the iPhone 7.

iMac: 10.15.7
Flutter: 1.20.4
VSC: 1.49.2
iPhone 7: 13.5.1
