I have a framework, it's developed in Swift and Objective-C. I created a fat framework for both and if I try to use it in a project, I am getting the error like:
Could not find module for architecture x86_64 found arm64,arm,arm7
for both frameworks. I am using Xcode 10.2.
If you’re building a framework containing Swift code and using lipo to create a binary that supports both device and simulator platforms, you must also combine the generated Framework-Swift.h headers for each platform to create a header that supports both device and simulator platforms. (48635615)
For example, if you’ve built:
- iOS/Framework.framework
- iOS Simulator/Framework.framework
Take:
- iOS/Framework.framework/Headers/Framework-Swift.h
- iOS Simulator/Framework.framework/Framework-Swift.h
Create a new:
- iOS + iOS Simulator/Framework.framework/Headers/Framework-Swift.h
The contents of the new Framework-Swift.h should be:
#if TARGET_OS_SIMULATOR
<contents of original iOS Simulator/Framework.framework/Framework-Swift.h>
#else
<contents of original iOS/Framework.framework/Framework-Swift.h>
#endif

Just run into the same issue, was able to fix it using the script stored here:
https://gist.github.com/quangDecember/9f7d65964b7df8d71c4a1cfd4f95c0ee
Just replace your script that creates a fat framework with the one from the link. This works perfect for me. XCode 10.2
I have the same issue, the only option was to ran the app in a real device. But if you just want to build the project, then choose the "Generic iOS Device" option and no the "iPhone 6", "iPhone 7" or others.
There's not really a solution for this except ask for the framework's owner to release a version with an architecture x86_64.

I have a simple C library that I'd like to distribute as a single framework for all three platforms — iOS, Mac, and the iOS Simulator. I'm aware of the fact that it's possible to configure Xcode (or use lipo) to generate a fat framework that contains the arm architectures and the i386/x86 architectures, but from my testing it appears that the overlap between the shared architectures of the iOS Simulator and Mac leaves room for only one or the other (Xcode gives warnings when using the Mac x86_64/i386 binary compiled for the simulator.)
Is this at all possible?
xcframework is new in Xcode 11, and may make this possible. From the Xcode 11 Beta Release Notes:
XCFramework make it possible to bundle a binary framework or library for multiple platforms —including iOS devices, iOS simulators, and Mac Catalyst — into a single distributable .xcframework bundle that your developers can use within their own applications. An .xcframework bundle can be added to an Xcode target’s Link Libraries phase and Xcode uses the right platform’s version of the included framework or library at build time.
And you already linked to the relevant talk from WWDC 2019
I have a swift framework and I use on objective c project. I create a fat framework with script. It works till Xcode 10.2.
I try to create fat framework on Xcode 10.2. It compiled successful but when I added on my objective-c project it not working on simulator.
Apple's release notes include my error but I didn't work. (https://developer.apple.com/documentation/xcode_release_notes/xcode_10_2_release_notes in known issues)
How can I create fat framework headers file for simulator?
Try this one

This use the workaround proposed by Apple
I just upgraded from Xcode 6 Beta 2 to Xcode Beta 3 and am now getting the following warning when building my project:
ld: warning: relocatable dylibs (e.g. embedded frameworks) are only supported on iOS 8.0 and later (#rpath/libswift_stdlib_core.dylib)
It is a warning but seems to mean my current setup will not work on iOS 7.1, which is my deployment target. How can I track down which frameworks are embedded, and how can I fix this for iOS < 8.0?
This appears to be a bug of Beta 3. As pointed out by Apple Engineer on this post.
I have also been living with this warning when running apps on iOS 7.1 device.
You see and add them on the project page when you select the target: tab General->Embedded Binaries (and they then appear in Build Phases->Embed Frameworks).
Embedded frameworks for OSX were available in Xcode 5, but not for iOS.
WWDC session regarding new features in Xcode 6 specifically promised dynamic frameworks for iOS 8 (someone please add citation when developer center comes back online). So far, with all Xcode 6 betas, I have had no problems compiling and debugging an app with frameworks on iOS 7.
But since this wasn't promised, frameworks for iOS7 is something you cannot depend on (e.g. this may stop working in later betas; an app with embedded framework for iOS 7 may be rejected, etc.). That may explain why they added an explicit warning.
There's not much you can do if this feature turns out to be indeed unsupported, other than remove the frameworks from the target and use static libraries as we did with Xcode 5. Or go the iOS8-only route.
After using XCode 6.1.1 I am able to put the code on iOS 8+ iOS7.1.2 and iOS 6.1.3 Although the warning is still there but the app works absolutely fine on all the 3 OSs
======================
Lucky guy... My project keeps failing to compile after I referenced the PushKit framework.
The project is a new project created by Xcode with only 3 new functions for testing Push Notification.
The workaround is to put the PushKit framework as "embedded", but this is not a good solution since my working Xcode project will be generated from Unity3d. Making the changes manually will break the auto build process.
I had this error after adding a C++ framework (DeepBelief) to a project. Adding an empty .cpp file to the project fixed it.
I'm using Beta4, and found the answer on the DeepBelief github site:
XCode may be skipping the standard C++ library, and that's needed by
the DeepBelief.framework code. One workaround I've found is to include
an empty .mm or .cpp file in the project to trick XCode into treating
it as a C++
project.
Read this github post from ReactiveCocoa
The bug is still present in XCode6 GM and so XCode6 final release:
Well, I get the exact same issue in xcode6GM no matter whether I
create framework for swift OR objc :-[[[[[[[[[[[[[[[
According to Apple Extension Programming Guide:
You can make a containing app available to users running iOS 7 or earlier, but then must take precautions to safely link embedded frameworks when running in iOS 8 or later.
talking about app extensions, but if you read it, you can understand that this applies to embedded frameworks in general.
this is happening because one of your embedded binaries's deployment target is lower than your applications target. lower your embeded binaries's building target and be fine.
this was the error cause in xcode 6.1.1
i was using xcglogger with deployment target ios 8.0, and my application's deployment target 7.0. set the xcglogger's deployment target ios 7.0 and problem solved.
After using XCode 6.1.1 I am able to put the code on iOS 8+ iOS7.1.2 and iOS 6.1.3
Although the warning is still there but the app works absolutely fine on all the 3 OSs
Yes not able to submit the app for review.
Had to do by changing the modern frameworks to Static libs.
I have a Xcode project, that includes a Static Library project, that uses another static library that does not support the iOS simulator architecture (Vuforia SDK: libQCAR.a).
Vuforia SDK documentation states:
Vuforia applications must be deployed to a device to run; they cannot be run in the iOS simulator.
This is my project structure:
MyApp.xcodeproj
Classes
MyStaticLibrary.xcodeproj
Classes that depends on libQCAR.a
Frameworks
libMyStaticLibrary.a
libQCAR.a
My problem is that MyApp.xcodeproj does not build for the iOS Simulator because libQCAR.a is not built for the i386 architecture.
Is there anyway to make MyApp.xcodeproj ignore the libQCAR.a library when building for i386? I would be able to disable all the code that depends on the library with #if !(TARGET_IPHONE_SIMULATOR)
You can use a conditional build settings to specify the library you want to link only on a given platform, instead of adding the library to your project in the usual ways. Specifically, you will need to specify:
-lQCAR
in "Other Linker Flags".
Have a look at the attached image that should make things more clear (in the picture I am linking only for the simulator, you will want to select a device, I guess).
Also, do not forget to add the path to the directory containing the library to "Library Search Path" build setting (this does not need to be conditional; it would not do any harm on the simulator).
This issue seems very similar to: Xcode: Conditional Build Settings based on architecture (Device (ARM) vs Simulator (i386))
I believe sergio's solution is very close, but have you tried specifying the full path to the library under Other Linker Flags (potentially without "-l" - just the path)?
In my case, it should specify clearly which SDK uses which flags.
So in Any iOS Simulator SDK, you should not include the library.
In Any iOS SDK, you should include it. In my case, it's -lCloudReco.
The latest release notes indicates 4.2.1 and lower will not be supported, we now have to use 2 version of Xcode to develop when supporting older devices?? This is going to be difficult to support older devices if we want to develop iOS6 AND support 4.2 and lower.
I don't think Xcode 4.4 will support iOS6. So this is the issue. How would developers easily support these platform without so much hassle?
You can do this, but it requires some minor Xcode hacking, and some sacrifices. Depending on what you mean by "support iOS 6", this may or may not be sufficient for you. If you just want your app to run on iOS 6, then this should work. If you also need your app to incorporate new iOS 6 features, then it won't.
(Note for others who don't have a problem using multiple versions of Xcode: this similar question has answers that do allow you to also use new iOS 6 APIs and directly target armv7s)
See basic instructions on chpwn's blog here (but read the rest of this below, too!)
Basically, you can use Xcode 4.5 to build for iOS 4 and above, but then you can't take advantage of the new iOS 6 only features. So, you're really building for iOS 4 and 5, and assuming that the app will run fine on iOS 6 (which should be true, but you'll need to test this yourself).
You'll need to copy the iOS 5 SDK folder
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.*.sdk
from an old Xcode installation (which you'll need to keep around briefly, or reinstall to a non-standard location). You'll then set the Deploy Target in your Build Settings to iOS 4.0 (or whatever minimum OS you want). You may need to open the project.pbxproj file in a text editor to set this manually:
IPHONEOS_DEPLOYMENT_TARGET = 4.0;
You'll also need to set the Architectures to armv6 and armv7. You cannot directly also target armv7s. But, that doesn't mean your app won't run on iPhone 5. armv7 executables should run on iPhone 5, simply without any optimizations added in armv7s. It's just that compatibility doesn't work in the other direction (e.g. armv7 executables don't run on an armv6 iPhone 3G).
There's also a step that might be necessary, that's not mentioned in chpwn's blog. You may get these warnings (which really are errors, because Xcode won't generate your executable properly):
warning: no rule to process file '$(PROJECT_DIR)/main.m' of type sourcecode.c.objc for architecture armv6
In order to fix this, you'll need to setup a custom Build Rule for your target that tells Xcode to use LLVM GCC 4.2 to generate armv6 code. Define the rule for files matching the pattern *.[mc]:
This will be a different compiler than the Xcode default, and you may need to adjust some of the syntax in your Objective-C code. Even though many people wanting to do this probably wrote their apps before ARC, it is important to note that LLVM gcc 4.2 does not support ARC.
Finally, you probably will still see warnings from Xcode about iOS deploy targets less than 4.3, and armv6 not being supported. Those, I found, were not problems, and could be ignored:
Running lipo -info on my app executable after this shows the desired result:
lipo -info MyAppName
Architectures in the fat file: MyAppName are: armv6 armv7
Xcode 4.5 makes iOS 4.3 the earliest supported operating system, which effectively orphans the original iPhone and the 3G.
If you want to support iOS versions earlier than 4.3, you will need to keep around a 4.4 version of Xcode.
To be a bit clearer : you cannot easily (meaning Xcode does not out-of-the-box) support pre-4.3 devices and use iOS 6 features in the same app. That's because iOS 6 features require XCode 4.5 which also sets iOS 4.3 as the minimum supported OS.
So, you have 3 choices :
Continue using XCode 4.4. You'll be able to target pre-4.3 iOS. You won't be able to take advantage of iOS 6 features, but your app should run fine on it assuming you perform adequate testing on actual iOS 6 devices.
Migrate to XCode 4.5. You won't be able to target pre-4.3 iOS, but you'll be able to take advantage of iOS 6 features.
Make two versions your app. Build one version with XCode 4.4 (as in option 1), and the other with 4.5 (as in option 2). From the point of view of distribution, these will be 2 separate apps, they'll each have their own bundle ID, etc. You will have two entries in the app store.
If you are comfortable going beyond what is supported directly by Xcode, see Nate's answer.
The original iPhone and iPhone 3G are the only devices that don't support iOS 5. The iPhone 3G is now 4 years old. You may want to consider dropping support for iOS 4. If you don't want to do that, I think you'll have to develop in two different versions of Xcode.
I assume that the dropped support for iOS 4.2.1 is not the core problem. In fact, I tried to work around this and do the following:
Build the app with iOS 6 SDK, setting deployment target to iOS 4.2.1 (which works).
Pack the app for ad hoc installation and install the app on an iOS 4.2.1 device (iPod touch 2G).
Test the app.
However, installation fails. The reason here is - afaik - not the iOS version. The reason is the architecture. XCode 4.5 no longer allows you to build for armv6. It only builds for armv7. On the other hand: all device which have armv7 or better can run iOS 5. The only devices which do not support armv7 are iPhone, iPhone 3G, iPod touch 1G and iPod touch 2G.
So for me the question is: can you build for armv6 with XCode 4.5 and iOS 6 as base SDK?
Edit: Which you cannot do, because the iOS 6 base SDK is not available for armv6. Right?
Try to set the project settings manually using IPHONEOS_DEPLOYMENT_TARGET=4.0. However, I don't know if there is any side effect.
I think that targeting to 4.3 is the best choice, according to ios version statistics
