Screen Initialize not working with built iOS App .ipa

[Jacques_Dumarest]

Screen Initialize not working for me with iOS built .ipa Ad Hoc App, OK with Companion.

Here is the small test App: Just a label initialized when Screen1.Initialize:

When running the App on iPhone, getting error: invoke: unable to invoke method 'environment' in object of type #!null. Irritants:()
Label is not updated
Screen Initialize not implemented: Irritants error + not executed ?
Here is the very small test App

I had already pointed out this problem some time ago. So the MIT team should know.

Affects only compiled apps (IPA): There must not be a non-empty Screen.Initialize event on any screen. There can't even be an empty Screen.Initialize event on Screen1. Instead, I replaced the Screen.Initialize events of all screens with timers. There are now no more problems/error messages. There are no problems when switching the screens, as long as you don't want to open other screens via Screen1, but only switch between the other screens (non-Screen1 screens). When switching to another …

Hello @Anke
Why is running well with iOS Companion and not with IPA file And Hoc?
The builder will be the same. I don't understand it.

@Ferran_SIMON

I don't understand it.

There are countless reasons for this. Furthermore, there are of course also significant differences between Companion and the compiled app on Android.

@ewpatton is possible to have the same results with iOS-Companion ant the .IPA files?

[Ferran_SIMON]

I claim not for little differences, for example on layouts designs. I claim for a big problems, for example to have fatal errores whith the .IPA files and all good n iOS Companion.

Thanks a lot @Anke
I'll add this tip to Some tips when porting App to iOS

OK, I understand that it is still Beta version with some potential issues. For info, I am using a old iPhone 7 with iOS 15.8.
I know it is a huge work to make it (Thanks to @ewpatton )available on iOS .I am following this activity since few years, waiting for it!, And I think it is time to do it and participate to this Beta testing

As Screen Initialize cannot be used, if I understand well, the default values of the different components provided in the Designer screen are not used and I have to initialize the components in the Timer.
I am currently using "Fill parents" feature to organize my App layout, but this "Fill Parents" feature is not available in the Block screen. E.g set Label width to Fill Parents ?

[Anke]

-2 for "Fill parent" and -1 for "Automatic"

Great! Is it documented somewhere? I do not see it in the help
