Hi Panos,
Thanks for replying.
Re the version of Xcode, I think I was giving too much detail, and this part
is probably not relevant. I started working with 13.2, and only launched it
(and caused it to auto-update) after encountering problems - but it probably
made no difference to the problems (it was days ago, I can't recall exactly
the sequence) so you're right if I hadn't had those issues I'd probably still
be using Xcode 13.2 and it would probably be fine.
However, I think the mystery here (at least to me) is why I was unable to
build, for iOS 15.2, until I had installed the iOS 18.1 simulator.
(The splash screen thing remains a mystery, but I think it will never be
solved - and I can't reproduce it. The only property with an image was to the
correct image I wanted. Somehow there is a method to make an animated sequence
of splash screens!)
best regards,
Ben

Hello Ben,
Ok, so what you see RE Xcode happens because:
- As of LC 10.0.1 RC-2, it is no longer required to have a specific version
of Xcode / iOS SDK installed. LiveCode uses the one that is returned if you
run this command in the Terminal: xcode-select -p
- As of Xcode 15, the simulator runtimes come as a separate download - and
one is required to download them if they want to use the simulator.
So, if your existing Xcode 13.2 had not auto-updated to Xcode 16.1, LC
would have picked this instead, and you would not be required to download
any additional runtimes, since the simulator runtimes for this version were
already bundled into the original download.
Does that make sense?
RE the splash screen issue, it seems that somehow the old splashscreen has
made it into the standalone settings. I guess this does not happen with a
brand new stack, is that correct? You can have a look at the custom
properties of the "problematic" stack, and check the custom property set
"cRevStandaloneSettings". If you find there any property related to splash
screens, that its value is the path to the screenshot you see, delete it
manually.
Hope this helps.
Kind regards,
Panos

It's been a long time since I tried to build an iOS app, I thought I'd try
to
get it all working again. Inspired by Panos' release notes, I downloaded
10.0.1 (rc 3), so at least I wouldn't get the dreaded "Selected Xcode must
have..." message.
I checked the handy table at
https://livecode.com/resources/support/ask-a-question/ and confirmed that
at
least LC 10.0.0 (not 10.0.1) would work with Xcode 13.2 (which is what I
had)
on MacOS 13.4+ (I'm running 14.7) for iOS 15.2. I also read again the
lesson
at
https://lessons.livecode.com/m/4069/l/565715-how-do-i-become-an-ios-developer,
which confirmed that LC 10.0.1 would work with any Xcode from 12.4 on.
After a few false starts, I decided to explicitly launch Xcode and check
it
was all running. Sneaky Apple! It automatically updated itself to 16.1!
However, it still shows that it has the 15.2 simulator, and indeed I can
launch the simulator.
However when I re-launch LC 10.0.1rc3, create a new stack with a single
control on it, set the standalone settings build for iOS, iPod and iPhone,
15.0 or later; set the Test Target to iPhone Simulator 15.2, and click
Test,
the result is this message:
Unable to build app for simulation: failed to create launch
screen: /*
com.apple.ibtool.errors */
/var/folders/y7/gddpm8ys0892ztpvq78knn2m0000gq/T/Temporaryltems/tmp.93209.5TVqiHma/
trashme.app/LaunchScreen.storyboard:
error: iOS 18.1 Platform Not Installed.
I really don't want to build for iOS 18 - I only want to build an app for
my
own phone, which doesn't support 18.1 - but at this stage would be happy
if I
could just get to the next stage. So I installed iOS 18.0 Simulator from
the
Xcode Settings>Components window.
Same result.
Finally I went to Apple's dev site, and downloaded the 18.1 Simulator and
installed it from the command line.
Success! And it successfully built an app that launched on the 15.2
simulator;
and (after another couple of days, trawling through Panos' helpful
responses
on various forum postings etc) also on my phone running iOS 17.
So the first issue is why the 18.1 iOS Simulator is required, in order to
build for any other iOS version.
However, there is a remaining oddity; when the app launches, on the
simulator
or my real device, the splash screen is a cropped image of the dialog
bearing
the above message:
https://www.dropbox.com/scl/fi/de06nj2fkxay6nsgb97qp/Screenshot-2024-12-12-at-18.38.03.png?rlkey=d70pjfg7msik4e5f9dsgl89zm&dl=0
How curious. At some point I thought, well what happens if I actually take
the
trouble to assign a splash screen? So I looked at the Standalone Settings,
and
it turned out that there was a file assigned for the Launch image, and in
fact
it was a screenshot I'd made of that dialog, while I was working through
the
issue.
Mystery solved I thought, perhaps at some point I carelessly assigned that
and
had forgotten about it by the time I finally got a working build. So I
deleted
it. Same result! Then I replaced it with another image.
Now when I launch the app, it first shows the picture of the error dialog,
then the newly selected launch image. If I delete the launch image, it
just
has the error dialog as splash screen. Replace with a different image, I
get
the two-stage splash as before; first the image of the error dialog, then
my
chosen image. (All this persists through quitting and relaunching LC, btw.)
Has anyone else seen something like this?
Ben
