There seems an error in the testing bot:

# github.com/hajimehoshi/ebiten/v2/internal/graphicsdriver/metal
Undefined symbols for architecture arm64:
  "_objc_msgSend", referenced from:
      _addSublayer in _x002.o
      _setFrame in _x002.o
ld: symbol(s) not found for architecture arm64

I found #2243 (comment) still exists. Please take a look, thanks

yeah it wasn't linking to QuartzCore since that got removed from metal and wasn't in the iOS specific code.

Should hopefully be fixed now.

Other errors:

cannot use float64(width) (type float64) as type cocoa.CGFloat in field value

Hmm I’m not sure why it’s complaining on iOS although I did just remember I was using a modified version of purego so I’ll create that PR tomorrow morning

So, we have to update purego in go.mod in this PR, right?

Yes

Uh no sorry. I meant I like the consts one. What I wrote was very unclear

No problem, the const way is also fine!

I'll test this with actual devices tomorrow, thanks!

It seems like an iOS emulator and an actual iOS device worked with this PR. I'll double-check this PR as this is pretty big.

I would test on actual device again since I did a pretty big refactor. I moved the common OBJC objects into the cocoa package because they will be needed when ports the rest of Ebitengine
