The test server for the iOS build capability has been updated. Since the last update, the following issues have been addressed:
Fix an issue where the File component could not read packaged assets
Fix issues related to BackPressed, OtherScreenClosed events not firing
Fix an issue that would lead to components being garbage collected after screen switching
Make Web requests use a higher priority
Make the default URL session immediately fail when no internet connection present
I still have a bunch of issues on my list that I still need to work through. If you find any further issues based on the changes above, please let me know.

Unfortunately this error has not been fixed, at least not on an iPhone 6s (iOS 15.8.2).
On an iPad 12 Pro (iOS 17.4.1) the back button on the top left works, but swiping from the left edge to the right doesn't work here either.
The problem was and is only with the compiled app (IPA).
The first issue about BackPressed and OtherScfreenClosed firing events is running well for me. And the parameters are well moved into the screens.
But the seconf issue about Garbage collected after screen switching is not run well. If you generate the IPA for the attached AIA and test it, after 5 or 10 times that you are switching between Screen1 and Screen2 (go -return, more or less 5-10 times) the App misfire with a fatal error.
In my real App it happens at the firtst time that I had return to Screen1 from Screen2 because it is a big source AIA code. In the attched AIA (small source code) it happens after 5 o 10 times (it depens of the test).
The AIA source code attached to test has my profile to generate the IPA (you would need to change it) testNavigation.aia (12.9 KB)
This issue is running well in my App. The answers of the GotText server request is good and not delayed as we had in the prior version.
=====================================
In this issue I have not the fire event for Sreen ErrorOcurred block. The App will be waiting permanently and I only can stop it without a message for the user.
Without this block I can not manage this mistake on the App. In Android I manage the errorNumber 1101 and 1103 as a not internet connection present. In iOS is not possible it.
I suposse that in others internal app errors we will not fired this Screen ErrorOcurred block.
It also works for me on an iPhone 6s and an iPad 12 Pro (17.4.1), but not on my new iPhone 15 Pro Max. I will also check it later on an iPhone 13 (with the current iOS version 17.4.1).
The Backpressed event is not triggered in your test app on either the iPhone 56s or the iPad 12 Pro. So neither the back button at the top left nor swiping to the right works.
We are talking here about this
and you didn't even use this event. So I'm wondering what you actually tested.
If this event is present and defined, it will not work on an iPhone 6s, nor will it work on an iPad regarding swipe right.
Hi @Anke
If you see the attached aia you can see that I manage the back screen2 to Screen1 with an app button and not with internal iOS buttons. I don't need the left up iOS button.
@Anke I put the block BackPressed top-left button in the Screen2 and it runs well and returr the right parameter rom Screen2 to the Sreen1 f. But at 2 or 5 times that you repeat the procees it generate a fatal error.
The new aia with this additional ios top-left button back: testNavigation.aia (13.1 KB)
You are in the right topic here. Put more info of your problem or put your AIA source code. In my App for iOS is running well all the external access servers to GET, UPDATE o DEL info in a external Data Base via PHP.
In iOS remember to put also this additional block (not necesary for Android):
I'm sorry but I can not help you in this case because I have this operation with a PostText block and I manage the data base operations with PHP internally on my server with retunr answers to the app via GotText.
Ohh¡¡ I remember that the Dictionary blocks ara not yet implemented in iOS. It will be in the future. You must use only Lists (transform The Dictionary in List and tray again)
