LÖVE does not support iPhone 5 (?)

LÖVE does not appear to work on the iPhone 5 emulator from Xcode. Running a LÖVE game in Xcode yields the following error:

Code: Select all


wrap_Math.lua:35: Cannot push love object to Lua: unexpected alignment (pointer is 0x7a2453c8 but alignment should be 16)


[C]: in function
wrap_Math.lua:35: in main chunk
[C]: at 0x000x0780
[C]: in function 'require'
[C]: in function 'xpcall'
[C]: in function 'xpcall'
(iPhone 5s and later appears to work fine)

My guess is that LÖVE uses a feature that the iPhone 5 isn't compatible with. Consulting the chart at the following link: ... atrix.html leads me to believe that LÖVE uses arm64, metal, or opengles-3. If LÖVE uses one of these, then I can list it in a .plist file to say that the device just isn't supported, no big deal.

To recreate, run LÖVE on the iPhone 5 emulator and run a game. The problem has persisted for me no matter what game I run; even a .love file consisting of an empty main.lua still has the error.

I am running MacOS Mojave 10.14.6 on a MacBook (Retina, 12-inch, Early 2015). Xcode version is 11.3.1, LÖVE version is 11.3 .

Thank you.

Does it have the same problem on an actual device? The simulator may not match up with the device's behaviour for that sort of problem.

love doesn't currently require any feature that the iPhone 5 can't provide. That being said, I wouldn't bother supporting such an old device, especially since its hardware is so different from every iPhone released after it (32 bit vs 64 bit).

Unfortunately, I do not have an iPhone 5 to test it on. Admittedly, my main concern is that not supporting the iPhone 5 will prevent it from being accepted onto the App Store. Apple has officially dropped support for iPhone 5, but I'm not sure if I still need to support it in order to get past their approval process. Googling did not lead to a definitive answer, so I'd appreciate any insight.

Thanks for the help!

The iPhone 5 has a screen size of 4 inches, but there's no place for a 4 inch screenshot for the App Store on the App Submission page, so it's looking like I do not need to support the iPhone 5.

My app (metro.drone) was approved by the app store, so it looks like iPhone 5 support is not necessary. Thank you!
