When I compile my code on Xcode Version 8.0 beta 4 (8S188o) I get this single error bringing the compilation to failure:
Command
/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc
failed with exit code 1
I tried to clean the project and wipe the derived folder but that did not change things.
What is it and how may I know more about it?
When I try to compile on the terminal the error being reported is:
Invalid bitcast\n %.asUnsubstituted = bitcast %swift.error* %13 to
i2, !dbg !438\nLLVM ERROR: Broken function found, compilation
aborted!\n
Happened to me, when I had two classes with the same name in my project. After deleting the redundant one, error disappeared.
If you look above the error, Xcode will tell you which ViewController is added/declared twice, navigate to it and remove the reference. Build and you're good to go.
I am going to tell you my silly mistake, the error is showing the issue and It took 3 hours to me to understand. look into below error
look into above 2 lines of error, the problem is shown, Obviously, In my case Xcode is complaining that Location.swift and Customer.swift file is missing, look into my project hierarchy, the same issue can understand.
It's my advice to everyone that first understand the error and then look into issues. I removed my desktop files, which were referenced in the project, and therefore compile error occurred.
Clean your project that fixed my project
Product/clean
I got this error for core data models that i've created manually.And it got resolved by changing particular entity's 'Codegen' attribute to 'Manual/None' under Data Model Inspector.
If you change any file folder location or change any Objective-C Bridging file path. Then it's happened some time.
Update your Bridging path.
Clean your project alt + Shift + Command + K
Quit Xcode completely Command + Q
Open project again and wait for Xcode to index files.
I got this error when I was trying to run an xcode project. A swift file wasn't being found and complied correctly, even though clearly in the xcode project file you can see the swift file and when you click on it in finder the file comes up as a separate xcode swift file. I solved this by:
Deleting the problematic swift file
Creating a new swift file with the same name
Xcode prompts that the file is already created, press replace
copy/replace the code/etc. in the file
Clean the project (for good measure)
Run the project
The problem went away by itself for mysterious reasons. Instead of the whimsical linking error I got a new bunch of errors due to Swift 3 fling which the app compiles and run fine.
The solution that worked for me is I had to delete the .xcdatamodeld file in my project and create a new one. This solved it.
I got this error and resolved by changing Xcode command line tools,
Goto Xcode -> Preferences -> Choose Locations tab
Choose required Command Line Tools from drop down, run the project error has been fixed.
In my case the error triggered when Xcode could not find a file/folder from the external Framework and dependency. In such a case just pod update / pod install do the job.
Try removing inactive file(deleted file) from Build phases...
Based on #Mohammed Rizwan N answer
If error not gone, do the clean project and close Xcode. Then click right button on .xcodeproj/.xcworkspace file and choose appropriate Xcode version.
In my case, I tried to run a project in Xcode9/Swift4, while the project was written on Xcode8/Swift3
1.Go to build settings and check the path of the info.plist file and bridging header file.
2.If not sure they are correct , from the left side drag and drop the files into respective fields .This creates the path automatically .
Clean the project and build again .
I created 3 new groups and put my MainVC under one of those groups. After I deleted one of the new groups I created, the error went away after I cleaned my project.
Please update your entire log which suggests the error, mine is telling me I have duplicated classes in file
Try closing Xcode, cleaning the project and building again.
At first, cleaning wasn't enough. I had to actually close it and try again.
I faced this issue when I resolved git conflict for the project file, which was for adding and removing some files.
What I found out is Xcode creates the folder named folder named "Recovered References", just search this from bottom left search option from Xcode and delete it. After you delete it you will only get an error for missing files. Resolve that by adding files again by right-clicking and selecting add files option. Once you are done with it project compiles with no error.
Happened to me when I found two swift files with the same name within the project, even if the classes have different names.
In my case error came when I moved my bridging-Header.h file from one folder to another. and when I checked in Build Settings -> Objective-C Bridging Header it was showing old path. Then I moved that file back to previous folder.
My problem was that my machine was running out of available space. Restarting it cleaned up ~8GB of temporary files, but I guess you can also delete something instead.
This is mainly because xcode is not getting the exact path of any file or duplication of file name under linking area.
In my case I have added bridge header file under Resources file and added the path in
BuildSettings->Objective-C bridge header-> bridgehearfilename.h
You should specify the exact path of that file in this section.
eg: BuildSettings->Objective-C bridge header-> Projectfolder/Resources/bridgehearfilename.h
Correct your file paths in the build settings then Clean and build the project.
For me it was ,
Product > alt + Clean Build Folder
OR
alt + Shift + Command + K
Do these 3 steps:
Clean Project: Shift+Command+K
Make sure low disk space shouldn't be on your mac
Focus on the upper lines of this error...Try reading them again...Paste those files that are missing or having some light icon in xcode project navigator and delete those files with light icon.
Hope you will fix the error.
I tried to run a project in Xcode12/Swift4, while the project was written on Xcode8/Swift3
so I install Xcode version 11.7 and run this work for me.
I was trying to convert syntax of old Swift project to new one as per few suggestion on Stack Overflow I tried converting it through Edit > Convert > To latest Syntax that did not work properly instead I started getting new errors shown as below
Command/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc
failed with exit code 1
And
Command /usr/bin/ditto failed with exit code 1
I tried Xcode 6.0.1 Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 1, but it's a different situation.
Have you tried to do clean with Clean build folder?
The combination keys is:
ALT + SHIFT + COMMAND + K
Try delete Derived Data folder and Build it.
Go to Xcode -> Preferences -> Locations for get the derived data path
Clean Xcode. (cmd+shift+k)
Quit Xcode completely.
Open project again.
Wait for Xcode to indexing files.
Now run your project.
Just had the same issue. For me it was because I had renamed some of the project directories. I had a ton of red files in my project navigator. To solve, follow these steps:
click on the directory in project navigator where many files show as red
Under "Identity and Type" in the File Inspector (on the right side), click Containing directory
Select the new directories
Rebuild - command shift K, command B
As far as I know there can be multiple reasons why a compiler fails. Although cmd+alt+shift+k will help most of the time. If this fails, then click on the error message and try to debug it.
For example in the image below, if you read the message, we get to know that, there has been a name duplication. Fixing the name duplication will fix the issue.
Just remove inactive file(deleted file) from Build phases
then
Clean Xcode. (cmd+shift+k)
delete Derived Data folder and Build it.
Go to Xcode -> Preferences -> Locations for get the derived data path or cmd+Alt+shift+k
OR
Just remove inactive file(deleted file) from Build phases
Cleaning the project wasn't working for me, this is because I didn't pay attention to the message right above (Xcode highlights only the final command).
In my case it was
<unknown>:0: error: filename "FileDuplicated.swift" used twice: '/../filepath/FileDuplicated.swift' and '/../filepath/FileDuplicated.swift'
<unknown>:0: note: filenames are used to distinguish private declarations with the same name
Command /../bin/swiftc failed with exit code 1
I had to change the name of one of the two files and it was solved.
Hope this can help someone, cheers
In my case it was due to the few swift files which has been showed grayed out in the Build Phases section. After removing those files it was successful.
In my case I deleted few files from project and when try to commit the code, the files was showing there . To solve this issue.
1. Open terminal
2. Type git clean -n // it will show you list of files which are deleted from project but still are saved somewhere
3. Type git clean -f // All unwanted files will be removed
In my case, it was "Other swift flags". I had declared a flag there but not -D, so this was not getting recognized and resulted in the same error
In my case swift development snapshot was selected instead of xcode 9.2. here are the steps and image.
xcode on screen and click on xcode top menu bar.
Than go to toolchains option and check on xcode 9.2. thats it.
Note: If no toolchain found in your xcode than download from Here and install it. (after installation restart xcode).
Happy Coding!!!
Ok, my turn now. In my case I had an existing project. I copied in a few files from another project. One of the files I brought in was SettingsViewController.swift and there was already a file by the same name I was not aware of. The files were in different directories of the project so no duplicate message was shown. The compile/link messages offered no clue to this. I figured out the issue by adding one file at a time to the project (there were 12 total) and the building each time until I found the offending file. I renamed the new file and project builds now.
In my case it was a compiler flag change that didn't work well. It took a few compiles before it actually started failing though! Xcode caches what it compiles.
I just had this issue. It's due to path references. Have you been moving files around and/or copying folders? Check if .xcodeproj is inside or outside of the main project folder. Also, make sure that the project's file and directory structure are intact.
/yourFolderProjectName/ <-- contains your .xcodeproj file AND folder with Xcode project name
/yourProjectFolder <-- here are .swift, info.plist, assets folder, etc.
/yourProjectXcodeFile.xcodeproj
Another thing to check:
In my case I had deleted a row in the "Other Swift Flags" section in the Build Settings screen under the Release setting.
That row had been a value for a compiler flag key/value pair. So the key was there but not the value.
Once I deleted the key as well, then the build worked again.
This issue is happening because of pods
So Follow the below steps to resolve this issue
Remove all the pods and re-install again.
Remove all the pods using below this command (rm -rf "pwd/Pods/")
Quit the Xcode and open it again and build the app with device (generic iOS device).
Now check this issue will be resolved.
I had this error when Xcode found two .swift files with same name. Rename one of them and build again.
Wait for completing the indexing and run the project again. You must get an error then check it which may be Objective-c bridging file not found error. This error comes if you are using any Objective-C library or code directly in the project and your project unable to find the bridging file in the system. This issue basically caused by, if project is unable to find any file in the system which is using in the project (path issue).
I faced this issue while using the Swift auto-generated header file in my project (named as 'TargetName'-swift.h) to use Swift classes in Objective-C.
There was a typo in the file where I had imported this swift header. Correcting the typo helped me resolve the issue.
Clean the build in Xcode cmd+shift+k.
Update the pods.
look the where errors showing.
Add the missing files in Xcode.
After Run the Code. Working fine.
Try below if none of the above working for you.
My project location was desktop/my_project_folder
I tried all above then i made simple change.
I create one more folder on desktop past my project
.
then...
Cause of problem in my case:
This problem occurred when i change my project name in xcode & project folder name from desktop.
I was working on a private pod and was also pointing to it locally. I had made some file name changes.
Hence I was getting this error.
All I had to do was to run pod install so it would reflect the file name changes. After that it compiled.
In my case I copied a core data entity and only renamed the entity but not the class.
So go to your xcdatamodel and select the enitity > rename also the class name
Had the same issue but with duplicate file references.
Deleting Derived Data and cleaning had no success. But I got it fixed by doing this:
Navigate to your project.pbxproj -> open with your text editor of choice(I use atom).
Command+F and find the duplicate file sources and then delete them.
Build/Run and should be fixed.
For me, it was the keychainAccess problem as described in this answer (my error messages were completely opaque, all I had to go by was 'failed with exit code 1')
I recently added the iOS-Charts framework to my Xcode Project. The project would build before I added the framework to my project, but will not afterwards. I am not even using any of the framework's features yet, it is not imported anywhere, I have just added it in embedded binaries according to the instructions here.
The build fail message: could not read data from .../AppName/Supporting Files/Info.plist': The file "Info.plist" couldn't be opened because there is no such file.
This does not make sense because nothing has been moved and if I remove the framework from the embedded binaries section the project does build.
Help will be much appreciated, thank you.
The error message has said clearly: The file "Info.plist" couldn't be opened because there is no such file. When you see this, double check the Info.plist file in your disk, to make sure it does exists.
If you removed the library and it start building again, it's more like the Info.plist is modified but broken. You may want to google and do some testing, like creating a new project and import the library to give a try. If the new project has the same issue, file an issue on its github page.
Turns out the project file for iOS Charts was moved when I was setting it up. The project file had to be dragged into the Xcode interface, not actually moved into the project directory.
I have met the same problem with you, as it said "no such file", and it provides the path of it. So I realized that I forget to copy "Supporting Files" to folder.
Notice the file in this screenshot:
the missing Info.plist
Then in your project: TARGET -> Building Settings -> Packaging -> Info.plist File
By the way, due to the bug of Xcode, you should build before import Charts.
Good Luck!
I just copied my project over to a new mac (xcode/iOS up-to-date). However, I'm getting Swift Compiler Error when I try to build/run.
<unknown>:0: error: opening import file for module 'Swift': Permission denied
Looks like its an issue with my bridger file. So I tried the following
Deleted the old reference under Build Settings > Swift Compiler > Objective-C Bridging Header
Added a new objective-c file and created a new bridge.
However, the error still persists.
Any clue what might be causing this?
Try looking the user permissions of your files and add your new user as the owner of those files. Make sure it applies to all descendent items using the finder get info Owner permissions
Possibly one of the most inefficient solutions: I ended up creating a new project and importing all files, frameworks, plist settings, build settings over. Took a while (the project is fairly large), but ended up compiling.
In my case the "Framework Search Paths" was wrong. There was absolute paths from another computer.
First of all, i'm now on this site so really sorry if i'm commiting some error posting this question.I'm trying to use the zipArchive class to manage zip files in an ipad project.
What steps will reproduce the problem?
Create a project.
Add the ZipArchive folder with their files.
Add the libz.1.2.3.dylib
What is the expected output? What do you see instead?
I have all the code (about ziparchive) commented, so i only have the #import #import "ZipArchive/ZipArchive.h" in my viewcontroller, and i expect to build the project without errors.
I see the following error in the compiler:
ld: warning: ignoring file /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2/Symbols/usr/lib/libSystem.dylib, missing required architecture i386 in file
ld: in /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2/Symbols/usr/lib/libobjc.A.dylib, missing required architecture i386 in file for architecture i386
collect2: ld returned 1 exit status
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/llvm-gcc-4.2 failed with exit code 1
What version of the product are you using? On what operating system?
I'm using xcode 4 a project for the ipad with the 4.2 ipad simulator on a Mac os X version 10.6.7
Please provide any additional information below.
I think the problem is with the libz.1.2.3.dylib library, and I have some guest of where might be the problem:
The libz.1.2.3.dylib path error is on iPhoneSimulator.platform, it is valid for ipad too?? If is not, which lib could i use for the same purpose with the ipad??
I'm not sure i'm adding the libz.1.2.3.dylib lib correctly. What I have done is: right-click on Resources folder -> add files to "myproject" -> search for the libz.1.2.3.dylib and add the 4.2 version of it from the path u could see in the compiler errors. I also try to add to the frameworks folder with the same results.
I'm reading lots of posts about how to fix similar problems but no one could help me.
Any idea of what I have to do to fix my problem??
Really thanks!!
You need to do this:
Delete libz.1.2.3 from your local Frameworks folder. You don't need it.
Select your project at the top of the Project Navigator.
Select your application target.
Open "Link Binary With Libraries".
Click the "+"
Search for "libz".
Select "libz.dylib".
If you are using Xcode 4.5.2 the screenshots below may aide you in proceeding through steps 2 through 5. I'm not sure if other versions of Xcode are the same or not.
If you are using xcode 4 or upper version of it than it seems that libz.1.2.3.dylib is not included in iOS5 sdk. Here is simple method to fix this:
Open your project in XCode 4.2
Remove libz.1.2.3.dylib from framework
Add new framework libz.1.2.5
Run you app
It works fine.
libz.dylib is an alias to the latest version (currently libz.1.2.5) so you can also navigate to the file's location in Terminal and create a symlink called "libz.1.2.3.dylib".
cd /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/usr/lib/
sudo ln -s libz.1.2.5.dylib libz.1.2.3.dylib
You could also link to libz.dylib, which I would expect to always point to the actual latest version, which is why Tricon recommends changing the project to just include libz.dylib. I'm not sure I'd delete anything, although it's not a whole lot different from adding a new symlink...you're still mucking around deep inside the guts of Xcode....
