My application was working perfectly fine, then I started integrating SDK for push notification and stop the integration in between. I even deleted the SDK from my project and trying to archive or run the app, it gives me the error:
lipo Error!! can't open input file.
Any help would be appreciated a lot, I have given enough time to solve this but failed.
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/lipo: can't open input file: /Users/XYZ/Library/Developer/Xcode/DerivedData/MyAPP-hjbmqpnmsoruqxbwlayqkjsojccv/Build/Intermediates/MyAPP.build/Debug-iphoneos/MyAPP.build/Objects-normal/armv7s/MyAPP (No such file or directory)
I got it to work, I just made a simple change in my Project target-> Build setting-> Build Active Architecture only and set this Build Active Architecture only to YES. And it's working fine now..
update After 6 months:
Again i face this issue after updating to Xcode5. This time i have to update Project target-> Build setting->Valid Architecture to armv7. I removed armv7s and arm64.
By Setting "Enable Bitcode" to "No" works for me.
Now i able to Run on Device and submit to App store as well.
Note that I got this when switching from Carthage to CocoaPods. Solution was to delete the "Remove Unneeded Architectures" in the Build Phases section.
This happened to me because I'm using cocoapods and the Pods project in the workspace had a different setting for "Build Active Architecture Only" than my main project (YES and NO respectively). When I set both to "NO" I was able to build and run on my device.
Try removing file(s) that you've deleted from Project target -> Build Phases -> Compile Sources.
Hope that helps.
Try to remove connected iPad/iPhone if there. This worked for my case.
In my case, I executed my application after some updates, then tried to commit it on git, and conflicts ruined my code. That was sad story.
But luckily I had one backup on my system and I replaced ruined code with my local code.
Now while executing I felt same problem. Then cleaning the project was the magical stick for me. I cleaned the project and I was good to go.
This was a cocoapods issue for me. I'm running 0.35.0, Xcode 6.1.1, and apparently I need to mention my targets in my podfile in order for all my cocoapods to work correctly with my targets.
At the bottom of my podfile, I added:
link_with 'Target A', 'Target B' ...
Add all your target names, close Xcode, run pod install, open Xcode, and it should build for you.
Here's the github issue: https://github.com/CocoaPods/CocoaPods/issues/2627
That error occurred, when I've decided to clean up my Derived data folder.
I had to call carthage update --platform iOS then call Clean in Xcode and build again.
Hope that can help someone
For me, this occurred because my main executable and a library I was statically linking with had different settings in Build Settings > Architectures. The library was set to only "Standard architectures" but the main exe was set to "Standard architectures (including 64-bit)."
I think what was happening was that when the build process went to link everything, it found it was missing the 64-bit versions of the libraries, causing this error.
Setting them all to the same value (either with or without 64-bit) resolved the issue for me.
I get this error when disconnect device from my Mac, press my project on my project name (near play/stop build button in upper left corner), select device -> [iOS Device] and press product -> build Also I want to mention that project has a lot of 3rd party libs and some libraries installed with pods.
I had this error after a rebase put a bunch of inaccessible directories (over and over) in my framework search paths. Someone did not import the frameworks they were working on until the very end, and left references to their own directory in the code. Solved by comparing branches and removing offending code from the pbxproj
None of that worked for me.
After a bit of digging (git reset, etc.) I found that my workspace was corrupted. I deleted the content of the project.xcworkspace and all went back to normal.
Reason why even reset didn't work is because the .xcworskpace is in my .gitignore (like many I guess).
In my case, the problem occurred because I had an object (AVAudioPlayer) instance variable declared with the same name in two controllers - the app delegate and one other controller. Strange, but the problem disappeared when I renamed one of them.
New potential answer for Swift: we isolated this error down to a single usage of the nil coalescing operator (??) in a category file. The operator is used elsewhere in our project without a problem, but in this specific file, removing it fixed the lipo error.
you must have to add .m files in Compile Sources of Bundle Target.
I updated one framework in my project but somehow missed committing/pushing its one file 'info.plist'(because of some problem in my gitignore file). Since then everybody else started getting this error. So just committing the missed info.plist file fixed the problem. Hope this helps someone.
i tried to re-select provisioning profile signing for both debug and release. this did fix the issue.
This generally happens after changing the Deployment Targets in XCode and is easily solved by "Product > Clean" before attempting a Build.
I'm using both Carthage and Cocoa Pods and this is how I fixed the issue without deleting "Remove Unneeded Architectures" in the Build Phases section:
• Go to "Build Phases" tab within your target
• Drag the "Remove Unneeded Architectures" (or whatever you called your script) to a higher row (e.g. above "Compile Sources").
• Clean and Build
Hope that helps!
Go to your project directory, find build folder and delete it. Then do a build clean and then build project.
I hope this helps
