questions on apple & gideros

pie

Hi, I just found a friend who can lend me a mac to run the latest xcode and I'd like to try to publish on the apple store.

I never did that yet therefore I think I will need to learn a bunch of stuff but I have a question:

Is there any way to test a gideros app on a real iphone/ipad before paying for their greedy subscription?

I guess that gideros player should work as it does on android, but as I understood you can't sign apps unless you have a developer subscription.. so for starters you have to subscribe to apple developer program. Am I right?

Is the xcode iphone simulator reliable enough as a "plan B" while thinking if I could gain at least enough to pay me the apple developer subscription?

thank you

Based on my experience, you can't launch anything on a real device nor a simulator if you don't own at least one target device in that faimily, and of course you can't sign them (which is also required for testing) if you don't have an apple subscription.

So basically you have to subscribe to apple developper program, and you have to register a physical device to your account to be able to launch your code even in a simulator (at least it used to be that way).

I managed to run a gideros player (signed to run locally) inside an iphone simulator, so I guess apps might work too without subscription

That’s indeed a very good sign.

I tried building an ios player with lsqlite, luafs, require and json plugins (which I need for my app) and evertything gets along well, but as soon as I add imgui I get this error and the build fails:

Do you think there is an easy-fix for that?

Looks like imgui_table.cpp isn't compiled in imgui plugin on iOS. I'll fix that
EDIT: Done https://github.com/gideros/gideros/commit/691937522bb7a88267c6eec27c5d379ff23e2b69

Thank you a lot! I am ready to test it as soon as you are

Thank you that was fast!

can I ask you to build it too if/when you have time?


P.S. same error on MacOS building: I don't know if your fix should have already fixed that too.

Yes, here is a replacement library for ios, to put in All Plugins/imgui/bin/iOS (unzipped):

Thank you a lot! Building iOS player now succeeds, the same issue persists in MACOSX build, but of course I replaced ios plugin only

My app using imgui get a SIGABRT error that crashes the iphone simulator due to (I'd say) this output:

_validateReplaceRegion:205: failed assertion `Replace Region Validation (origin.y + size.height)(512) must be <= height(64). '

Every "basic" Demo I tried runs ok

Yes, horse demo won’t work on iOS, because it only uses a glsl shader, while iOS expects Metal shader (MSL). Having to write shaders for all three languages (GLSL,MSL, HLSL) was what made me invent lua shaders, but horse demo was made long before that.

Lua shaders generate warnings though, as you see in particles demo, but those are just warnings.

P.S. for the records, I managed to build and run one of the pure lua examples directly on one iphone without an apple subscription!
But I was unable to run a gideros player: it was running and showing an IP but it didn't appear in gideros studio as a target.

iOS simulator is stricter than a real device about Metal, you should have seen a metal related log in your console just before the crash

I don't know how to check for a Metal specific log: if you do please tell me how to give you relevant information

the first message on console is this one, and its backtrace is the one I posted above.

_validateReplaceRegion:205: failed assertion Replace Region Validation (origin.y + size.height)(512) must be < = height ( 64).

I also have this (screenshot attached) if it could help

Thank you a lot

This is exactly what I needed, thanks.

Thank you for the bugfix! Now (2023.10) the app is building and running in xcode simulator showing only warnings. However I have a strange render issue on every font: those "lines" that seem to be poorly ai generated text should be real text.
Have you ever seen a similar issue? I'd say that there is some discrepancy between the font and its rendering bounds because I can almost see some letter here and there but those are stretched and scaled.

Thank you!

hgy29

What kind of font is it ? A Font, à TTFont, or a TTFont with charset ?
Edit: oh, it is an Imgui font, right ? So it may be related to the warning above

This should fix the issue: https://github.com/gideros/gideros/commit/db7bd4345778d0da72b3c8cf6111abb63068540b

Thank you for the quick fix, can I ask you to build it too when you have time?

hgy29

I built a replacement library for ios, here it is:
http://apps.giderosmobile.com/pre/libgideros.zip
It must replace the one in Templates/Xcode4/iOS Template/iOS Template

pie

Thank you, I am sorry for the delay: didn't have access to the mac yesterday

You fixed it! It now builds and seems to work perfectly inside the simulator!

I still have a lot of warnings though (53), I don't know how many of these are mandatory to fix, I can try to fix some, but I guess that most of them are out of my league..

Can you please take a look at this warning list and see if there is something "important" at your eyes?

Thank you again!

Had a quick look, and I didn’t spot anything that could cause a problem. I should take some time to silence them anyhow
