XTool – Cross-platform Xcode replacement

flax•8mo ago
Would this theoretically allow a Flutter app developer to build and deploy an ios app from Linux? God, I hope so.
candiddevmike•8mo ago
It technically violates the Apple Developer Agreement AFAIK, but that seems like yet another lawsuit waiting to happen IMO.
ronsor•8mo ago
Apple won't do anything right now as they're certainly afraid the courts* will slap them hard.

*Both US and EU now

saagarjha•8mo ago
They’re still rejecting Fortnite so I don’t think they’re particularly scared of anything
jchw•8mo ago
Epic Games sure is proving to be a formidable opponent, but they might be getting a little optimistic with thinking that Fortnite will be allowed to return to the App Store; after all, while they have been squabbling over App Store policies, I don't think any of the rulings imply that Apple still can't keep specific titles banned from the App Store at their discretion. In that particular case I kinda feel like Apple might be right to not be afraid, at least not right now.

(P.S.: Personally, I initially thought Epic Games was stupid for flagrantly violating the ToS on purpose. Was that really needed to actually file the lawsuit? I dunno; I'm no expert. But it looked stupid. It looks a lot less stupid now, but it still kinda looks like a tactical mistake.)

Maybe they needn't be afraid here either, but from a risk perspective it does seem like causing a stink here may not be their best move. They're still going to aggressively try to railroad people into developing on Mac; there's no iPhone Simulator on Windows or Linux after all.

yard2010•8mo ago
IMHO it's a matter of principle, showing the bully he has limited power no matter how big his muscles are.
chuckadams•8mo ago
In Epic's case it's just another bully who wants a piece of the first bully's turf.
tough•8mo ago
Goliath vs Goliath
solarkraft•8mo ago
Epic Games may do some despicable things too (this is about micro-transactions after all), but (as a software developer) in this fight I still find it reasonable to root for their side - them winning improves the world for a lot of us.
_blk•8mo ago
Yeah weird world. When Gates bundles IE that no one wants it's an abuse of power but when Jobs shoves his apples down your throat just to (try to) publish for their platform it's all OK.. Oh, or was that the lawsuit waiting to happen? ;)
freeamz•8mo ago
Same thing with the bank bail out, if Bush did oh my we will never hear end of it, but if cool president who smokes weed and get down some good music, then no one really call him out on it.
tgma•8mo ago
IIRC it is only a potential issue if the host machine isn't made by Apple. You can install Linux on a Mac and use this.

IANAL yada yada.

petabyt•8mo ago
People have been doing hackintoshes and macos VMs for years... And apple hasn't really done anything. So I doubt this tool will provoke them.
conception•8mo ago
Apple has killed the Hackintosh…. It’s just bleeding out still.
ofrzeta•8mo ago
How so? Seems like Hackintosh got kind of obsolete with Apple Silicon.
cyberax•8mo ago
You can't install XCode on non-Apple devices. Or use iMessage.
johnisgood•8mo ago
Is this the case? How does that work? Genuinely curious. I remember I had macOS (Mac OS X, actually) on my PC. My last Hackintosh was Mac OS X Leopard. Everything seemed to work well... back then. I even had XCode working.
zImPatrick•8mo ago
you can still install xcode - and also still use imessage if you configure your vm correctly, see kholia/OSX-KVM
cyberax•8mo ago
I tried that, and I can't make it work. Sigh.
cosmic_cheese•8mo ago
iMessage can be made to work with a hackintosh. You just have to go the whole way in making your hackintosh fully Mac-like with a fake but plausible/realistic serial number and expected network setup. You can’t stop at just getting macOS installed and booting.

I’ve had multiple installs in the past where it worked fine.

jonhohle•8mo ago
Who minds committing a little wire fraud and possibly screwing over some chump who really owns that serial number?
cosmic_cheese•8mo ago
How is it wire fraud?

While it’s ultimately up to the person doing the hackintoshing and thus an “honor system” thing, all the guides are pretty explicit about how you should generate serial numbers that are syntactically valid but cannot belong to real machines, for example that of a 12” Macbook manufactured in 2020 in Cork, Ireland (no such machine exists, as they were discontinued in 2019 and manufactured in China). That way there’s a small chance of collision with other hackintoshers, but no threat of accidentally using the serial of someone’s real Mac.

karlgkk•8mo ago
A long while ago, they put some company selling hackintoshes straight into the ground. Nobody tried since
nar001•8mo ago
Does it? You still need to install Xcode for the iOS SDK, so they're not really doing anything wrong?
notpushkin•8mo ago
I believe it allows usage on “Apple-branded computers”, so building iOS apps with xtool on Asahi is probably legit.

But yeah, I would probably use this for testing only, and do actual releases from macOS proper.

Cloudef•8mo ago
Afaik its already possible with darling. Nixpkgs also has xcbuild replacement, but not sure if it can handle codesigning.
gman83•8mo ago
Just use something like CodeMagic, I wouldn't risk getting your Apple account banned.
loic-sharma•8mo ago
This project helps but isn’t enough alone:

1. Dart can’t cross-compile from Linux to iOS yet. You could use Dart’s interpreter instead, but that’d significantly regress performance.

2. Flutter iOS projects use the Xcode project format, you’d need to migrate that to xtool’s project format

3. Flutter hasn’t finished migrating its plugin ecosystem from CocoaPods to SwiftPM - any plugin that hasn’t migrated to SwiftPM yet likely won’t work with xtool.

woleium•8mo ago
no android support?
landr0id•8mo ago
...this is for building apps targeting iOS and macOS on non-macOS platforms. Why would Android support be necessary?
woleium•8mo ago
Oh, i misunderstood. my bad!

I thought it was for compilation of ios apps for linux and macos.

thayne•8mo ago
So you can build iOS apps on your android device?

If for no other reason, it would be gloriously ironic.

lwouis•8mo ago
This tool says "Xcode replacement" and "Xcode-free development". I thought there is no way they can build apps without Xcode. How would they replicate the libraries, compilers, etc.

I dug more and of course they don't: "Though we don’t rely on the Xcode build system, you still need to install Xcode for the iOS SDK and toolchain"

I think they should clarify their messaging. This is not a replacement or an alternative. It's a layer on top designed for what they think is a better experience.

rockbruno•8mo ago
I think you are mixing some different concepts here. It's not that this is a layer on top of Xcode/xcodebuild, it's just that Apple today happens to package everything iOS/Swift-related together with Xcode releases. So even if you couldn't care less about the Xcode IDE itself or the xcodebuild build system, you still need to have it because this is the only way for you to download / install those toolchains. Apple could provide these separately, but they just don't.
notpushkin•8mo ago
Would it be possible to get just the SDK from the Xcode package? Like Asahi installer streams only the relevant parts of macOS images from Apple’s servers.
isodev•8mo ago
There are some components that may be downloadable separately but they really are part of Xcode. One ring to rule them all.
kabiroberai•8mo ago
I looked into streaming but afaict the XIP format doesn’t support random access the same way that ZIP does. specifically because 1) it doesn’t seem to have a Central Directory like ZIP and 2) it has an optimization where files can be hardlinks to other files (by ID) in the XIP, so if you want to extract a file but all you get is a hardlink ID, you can’t expand the contents until you encounter and expand the hardlink pointee. it’s possible I’ve missed something, open to ideas for sure.
notpushkin•8mo ago
I do have an idea that will add a lot of complexity for sure: you can extract Xcode, mapping out whick portions of the archive correspond to the SDKs we need, then use this mapping to only download these relevant parts, reconstruct the archive and expand it. Not sure if it’s worth it!
ImPostingOnHN•8mo ago
It sounds like this "cross-platform xcode replacement" isn't cross-platform, and ios app developers still need macos?
dadoum•8mo ago
But that's wrong. You don't need macOS. That's why they say "cross-platform Xcode replacement". You just need the SDK, which can be used on every platform.
mathstuf•8mo ago
IIRC, you need to run on Apple hardware for a valid SDK license. VM or Asahi or Hackintosh would suffice, but not a VM on a random Linux box. Or did the terms change lately?
ImPostingOnHN•8mo ago
Thank you. I did not make it clear enough that I was asking for clarification there.
kabiroberai•8mo ago
xtool creator here, this is correct. it wouldn’t have been possible to support Linux if xtool was just a layer on top of Xcode, as Xcode doesn’t run on Linux.

we only need Xcode to be installed on macOS since it bundles the iOS SDK (ie all the header files.) similarly, we ask the user to supply a copy of Xcode.xip during the setup process on Linux in order to extract the SDK.

it definitely depends on your definition of “replacement” in the end, but I (and most people I’ve spoken with in the iOS community) would consider “Xcode” to be the Xcode build system, user interface, and proprietary tooling. xtool doesn’t rely on any of this, not even for signing and installation. you can (read: must on Linux, may on macOS) use it with the open-source Swift and Clang toolchain + LLVM’s LLD linker and MachO tooling. Codesigning uses zsign, an MIT-licensed x-platform codesign alternative, and installation relies on the open source libimobiledevice project, which is installed by default on many Linux distributions (eg Ubuntu).

rushiiMachine•8mo ago
I'm not too familiar with the xcode dev environment; could Theos be used instead of the huge xcode bundle? As far as I know, it provides the compilers and frameworks directly.
kabiroberai•8mo ago
I’m also one of the maintainers of Theos :)

When you use Theos outside macOS, you have to install a toolchain and SDK. The toolchain is built from LLVM + cctools, and is in fact very similar to the one we use in xtool (I maintain both.) The SDK is hosted on GitHub and I could’ve decided to use this instead of getting the user to supply a copy of Xcode, but the copyright status is iffy; there’s an argument to be made in light of Google v. Oracle but I didn’t want to take any chances.

rushiiMachine•8mo ago
That makes sense, thanks!

I'm excited for the possibility of this being integrated with multiplatform frameworks like KMP. I wouldn't need to boot up my hackintosh anymore :)

lwouis•8mo ago
I've been developing a fairly popular macOS app for years. I consider myself in the community for that reason.

Apple has bundled everything together in a big mess.

- Only certain macOS versions can run certain XCode versions

- Only certain XCode versions contain certain SDK versions

- XCode embeds "Command line tools" which contains things like gcc, ruby, python, installed as a package, and conflicting with other versions on the machine

- Interface Builder is built into XCode and has its own compatibility story

It's a big messy blob and you can't pick-and-choose parts. You have to update your whole machine to move to the latest OS so they will let you run the latest XCode, so your app can compile on the latest platform for your users. It's not the best experience for sure. Many ecosystems have SDKs that you can download as you wish. I don't need to update my OS to download a version of the JDK for example.

That being all said, if you require users to download XCode, regardless of which part of it is necessary, i don't think you should mention "XCode free experience" or "XCode replacement".

I'm already developing a macOS app without launching the XCode GUI. I use the xcodebuild CLI that ships with XCode. My IDE is AppCode. I also use xcodebuild on CI to build the app headless. I would never call that a XCode free experience though, as i suffer from all the issues i mentionned above with version upgrades and XCode issues

firecall•8mo ago
JetBrains used to develop AppCode:

  AppCode

  A smart IDE for iOS/macOS development

  AppCode is no longer available as a commercial product as of December 14, 2022.

  https://www.jetbrains.com/objc/
lwouis•8mo ago
It seems that Fleet will support building XCode apps. It looks like a big regression from AppCode. As of today Fleet doesn't compile my macOS app. I try regularly on new updates. No alternatives, unfortunately
sandebert•8mo ago
What's Fleet?
tomcam•8mo ago
https://www.jetbrains.com/fleet/
Larrikin•8mo ago
Fleet will also most likely get abandoned as people who pay for an IDE highly prefer the older one and people who want VSCode use VSCode

I also think any revival of AppCode is also dead as JetBrains is all in on Kotlin everywhere. iOS multiplatform support hit stable recently.

BrandonSmith•8mo ago
JetBrains already announced it is no longer targeting Fleet as its iOS strategy for Kotlin Multiplatform. Instead it will be realizing its strategy through IntelliJ IDEA and Android Studio.
mdaniel•8mo ago
It likely doesn't help the ObjC part of that story, but they moved the Swift part out into a CLion plugin https://plugins.jetbrains.com/plugin/8240-swift

Regrettably I didn't see that they did anything with the ObjC part, choosing to /dev/null it

pharaohgeek•8mo ago
Unfortunately, even that isn't supported any longer. I do a lot of server-side Swift development and would LOVE to be able to ditch Xcode for CLion and the Swift plugin.

Yes, because the tool itself is just a command line app, replacing the build tools, but not the IDE. You edit the code in your tool of choice.

I see the Github org is "xtool-org". I wonder if XTool the company (makes laser engravers and other creative/crafting tech) will take issue.

Would be cool to have similar tooling (de-attached from XCode) for live previewing interfaces built with Swift UI.
novoreorx•8mo ago
Reminds me of Sweetpad (https://sweetpad.hyzyla.dev/), which is a bit tedious to setup, XTool seems to provide a better DX, huge wish for this project to grow!
novoreorx•8mo ago
Also it shares something in common with XcodeGen (https://github.com/yonaskolb/XcodeGen), especially on using a yaml format to define the project's information
