AppCode Support about hotreloading HOT 13 CLOSED

It's a warning.

from hotreloading.

When you say "doesn't seem to work" what happens/doesn't happen. Does the menu bar app run? Does it connect (icon goes orange)? Is there an error message you could tell me?

from hotreloading.

@johnno1962 Sorry about the confusion. It was simply that my code change didn't get updated right away when I tried with AppCode. But, I realized that I didn't set up the injected function nor notification. It is working now.

@johnno1962 Ha.. I'm getting confused with the whole thing. I thought HotReloading was working but it was a separate issue that caused a confusion for me. I see this error message when I save the Swift file from AppCode:

🔥 Loading .dylib ...

Oh.. Before this, I also had to not only link but also embed HotReloading library to make a crash go away. That crash didn't happen for Xcode.

Here's the message from the crash

My issue was linker flag misconfiguration. Sorry about the noise!

@johnno1962 First of all thanks for such a great job supporting this project!

Not sure if I'm doing something wrong or what but, I do have my project using HotReloading and it works great on Xcode 14.1 however when I open the same project using AppCode ( and specify the same Xcode version within Tools > Xcode ) as soon as I update any file I get a Re-compilation failed message.

Am I missing something?

from hotreloading.

Hi, I don't know. Can you tell me a little bit more detail of the exact message you're seeing? Have you checked the command.sh script file it mentions to see if it is valid? HotReloading as a package is slowly being phased out in favour of just loading the iOSInjection.bundle from the app but not running the app a.k.a. "Standalone Injection" (if you're allowed to use the binary releases). Perhaps you could try that?

Hi, I don't know. ...

Hi there, thanks for replying!

As I've seen it has something to do with the iOS versions I'm running, I've doubled check and, both Xcode & AppCode do trigger the same error when running my app on iOS 14.2, when running it on iOS 16+, it just works.

ld: warning: -undefined dynamic_lookup is deprecated on iOS Simulator ld: warning: object file (/Users/user_folder/Library/Developer/CoreSimulator/Devices/BE1565CF-F8F7-4864-BBD0-51A765EEBF27/data/Containers/Data/Application/350B32DE-146C-40C0-94E7-7210754EEDFE/tmp/eval101.o) was built for newer iOS Simulator version (13.0) than being linked (9.0)

from hotreloading.

Ah, I see. You can ignore the ld warning until they actually deprecate it but in fact, since Xcode 14 I've not seen an instance where you need to use -undefined dynamic_lookup which was a workaround for another problem so you can remove that from your "Other Linker Flags" now.

from hotreloading.

Well, I'm not sure I can tweak this flag, I didn't set it up.
