10.0.1rc3, building to iOS: Compulsory 18.1, strange splash screen

[panagiotis merakos]

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
