Building for iOS Simulator, but the linked and embedded framework ‘XX.framework‘ was built for

My App uses a static framework A (built as a dependency) which itself uses a static framework B. In Xcode 9 this built and worked fine. In Xcode 10 I get Undefined symbols for architecture x86_64 followed by a list of symbols used in A defined in B. However, nm shows the symbols are present in A:nm -m -arch x86_64 A | grep <missing symbol> (undefined) external <missing symbol>Why is this only failing in Xcode 10?

I can't build project with a new version of the opencv 3.0.0 framework (version 2 DID NOT have this problem).Xcode 7 does not compile c++ sources as c++.Here's the simplest setup that is not building:1. Download the 3.0.0 framework from here http://netix.dl.sourceforge.net/project/opencvlibrary/opencv-ios/3.0.0/opencv2.framework.zip2. Create the simplest ios project with Swift language.3. Drag-and-drop the framework to the project.4. Create the `Objective-C++` source and headers and add them to the project.5. Create the bridging header.Here's the setup:http://i.stack.imgur.com/vWp0X.pnghttp://i.stack.imgur.com/nQi8C.png6. Build.And here's what the compiler says:opencv2.framework/Headers/core/base.hpp:49:4: error: base.hpp header must be compiled as C++http://i.stack.imgur.com/Ak69F.pngWhy is that? I've got the `.mm` file and it is supposed to compile as the Objective-C++ source.

After upgrading to El Capitan, I now get this error when running my simulator for 7.1 using Xcode 6.3.2 (8.3 simulators are fine)1) I checked for /etc/launchd.conf and there is none2) I tried deleting the 7.1 runtime and reinstalling it from xcode / preferences / components3) I tried deleting and readding the simulator for the devices (4s, 5, etc)3) I tried Xcode 7 BetaHere are some logs from https://forums.developer.apple.com/message/5474#5474-Jun 16 11:55:30 com.apple.iphonesimulator[18024] <Error>: Error Domain=NSPOSIXErrorDomain Code=60 Unable to boot the iOS Simulator.

Hi,is there a way to recover the swift files of my App from a build version on the iOS Simulator or my iOS Device? I sadly lost a substatial amount of my code, due to errors in my backups. The last version i got is from February so i would apreachate any help i could get from you guys.Regards Adarkas

How to get iOS 12.5 for simulator in Xcode? I looked under Preferences - Components but 12.5 is not there and i could not find any documentation related on internet. I checked it on Xcode versions 12.2 and 12.4.

I am on macOS 14.3 Release Candidate with Xcode 15.2 and iOS 17.2 simulators installed. If I attempt to use iOS 17 features such as the SwiftData framework, it throws an error despite running my project on an iOS 17 simulator with an error such as 'model context' is only available in iOS 17.0 or newer. I am in an iOS App Playground but I don't believe that this will change much (correct me if I'm wrong). How could I fix this issue so I can use these features in my application? Thanks

I was recently running into an issue where I have a compiled framework that I embed into another application. This framework has both Objective-C and Swift code in it. The problem I was having was that none of my swift subclasses of UIKit based objects, such as UIViewController or UICollectionViewCell, were showing up for usage inside interface builder in my main project. All of the classes were available through use direclty in code though.After several days I finally discovered that the issue was if ANY of my swift UIKit classes used extensions, custom or things like UICollectionViewDelegate, then none of my siwft classes would be available in interface builder. However, if I moved the protocol implementations inside the class itself rather than an extension everything becomes available.I am assuming this has something to do with the compilation process of the code that it is generating something that makes interface builder unable to detect any of the swift UIKit classes.I was curious if

I am unable to run my app out of Xcode. I have been able to run my app off of my iPhone and simulators in the past so I am not sure what is happening. I continue to get this error: rsync: [sender] link_stat /Users/myusername/Desktop/ProjectName/GitHub Repo/packageName/node_modules/expo-structured-headers/ios/EXStructuredHeaders.xcframework/ios-arm64/* failed: No such file or directory (2) but i can see that the file does exist I also have updated my rsync and have done the usual delete pod.lock file and then do pod update, pod install, I have also tried pod deintegrate and pod install. I have tried my physical phone as well as a phone simulator. I have tried clearing the simulator cache, creating a brand new simulator, changing the directory name, upgrading the expo package, upgrading all of the outdated packages....not sure what else to do. Any help would be appreciated.

I've got a makefile that creates a library of object files using ar r mylib.a myobj1.o myobj2.o etc. Then I link with gcc main.o mylib.a -o myexe and I get the error above. Clear the error is complete garbage - it's complaining that I'm attempting to link with the architecture I've built for which is what you're supposed to do this isn't an error anyway! If I link directly with the object files it all works fine, so those objects are OK as is everything else. Something about putting them in a static library seems to hit a bug in ld therefore - evidenced by the garbage error message. The only other example I've found of this on google was 'fixed' by the poster using a more up-to-date version of the application he was compiling, so no help in what was the cause nor fix for the error. Anyone else come across this? Any thoughts on how to debug it further? Thanks.

- I have an iOS app that targets iOS 8.- It includes an Intent Extension (for Siri Shortcuts).- It runs perfectly fine on iOS 12 (device + simulator) and 10 (simulator).- It crashes immediately in the iOS 8 simulator and outputs the following: dyld: Library not loaded: /System/Library/Frameworks/CoreServices.framework/Versions/A/CoreServices Referenced from: /System/Library/Frameworks/Intents.framework/Intents Reason: no suitable image found. Did find: /System/Library/Frameworks/CoreServices.framework/Versions/A/CoreServices: mach-o, but not built for iOS simulatorI realize that I won't be able to use the Intents Extension on older versions of iOS, but I still want my main app to work. From what I've read online, I should still be able to target 8 even though I use SiriKit. Any Intent related code has been guarded against when iOS < 12.My project is configured like this:- Project De
