I am getting the following error when building in Xcode 10.0 with swift 4.2:
Moving the folders around the inspector can cause the error "Build input file cannot be found"
SWIFT 5
In Swift 5, the error came up but the identity showed no errors.
Go under build settings and select packaging.
Delete the current paths for Debug and Release and enter your new path where the info.plist is kept.
For example [APPROJECTNAME]/[THEINFOPLISTFOLDER]/info.plist
In the screenshot below, the path is API-client/Resources/info.plist
SWIFT 4
To fix it, go to the general tab and under identity reselect the info.plist that you like
Build input file cannot be found
How To fix This issue :
Go in the project-navigator, select your project
Select Build Phases tab
In Compile Sources section, check for the file(s) that Xcode is demanding of
Notice that the file(s) have the wrong path, and delete them by clicking on the minus icon
Re-add the file(s) by clicking the plus icon and search in the project.
Product > Clean Build Folder
Build
A most common error when you move Info.plist in another folder.
To fix this error you can select the Info.plist and choose Relevant to Project from file inspector.
Next step, go to Build settings and search for info.plist and fix the file path.
I got this issue after resolving the conflicts in project.pbxproj.
Step 1: Removing the "Build input files cannot be found" files from BuildPhases -> Copy Bundle resources and adding them back worked for me.
If the above Step 1 doesn't work, search for "Recovered References" folder in your project structure and remove the files that are causing this issue and repeat Step 1
For build file missing i.e. info.Plist :
Under Project navigator,
select(click) Project name and icon,
In middle pane, click target
click blue General tab on top
click / Targets
click [Choose info.plist File] button
in pop-up window, select the info.Plist file
I had the same problem with a missing view controller file that couldn't be found after cloning a project in a new folder. I deleted the view controller but the compiler continue asking for a file in a path that doesn't exist anymore.
I solved the problem as follows:
Select the project target in the Project-navigator,
Go to Build Phases tab
In Compile Sources section, check for the file that the compiler is asking for. You can filter by the name at the top right of the screen.
The deleted file is still on the list with a wrong path, delete it by clicking on the minus icon. You have to do it for all the target you may have.
In the case that you still use the file, add it on a new path by clicking the plus icon.
Clean Build Folder in the Product Menu.
It should work now :D
(Objective-C Project / Xcode Version 10.2.1 (10E1001))
This works if you get the 'Build input file cannot be found error message' and also have files that are red in the inspector:
Open your project folder in Finder
Make a copy of the affected files onto your Desktop
Delete the affected files in Xcode and then close Xcode
Re-Open Xcode and drag your copied files into your Xcode project
This worked for me. Before I got the error message I was re-organising files in the file inspector which gave me that error message and made the files I was moving around turn red. Hope this helps !!
I tried going to Compile Sources in the Build Phases tab and deleting and re-adding the selected file (and cleaning and rebuilding)but it didn't work :( Instead, this following answer worked for me if you get the 'Build input file cannot be found' error message:
Delete the affected files in Xcode (I right-clicked->Delete'd in the Navigator)
Re-add the affected file (mine was .mlmodel) and I selected "Copy items if needed" under Destination.
Cmd-shift-k to clean and then Cmd-b to build
and voila! The file was recognized and error gone!
Hope this helps!
For me this worked:
Click the app name under TARGETS
Build Settings -> Packaging -> Info.plist File
There change the file location of the Info.plist File to the new location.
DemoApp/Info.plist to DemoApp/Assets/Info.plist
I got this error when I moved my Info.plist into a folder.
When I took Info.plist out of the folder, I no longer got an error.
Change the build setting to legacy
First, open your project in XCode by double-clicking on ios/<YourApp.xcodeproj>
Then go to File > Project Settings...
Change the Build System to Legacy Build System in Per-User Project Settings:
Select general tab and under identity select the info.plist you want for your development
For me something totally different worked:
Go to Target>Build Settings>Architectures
My valid architectures before: arm64 arm64e armv7 armv7s (Defaults)
Changed it to: armv7 i386 arm64 armv7s
In my case I got this error when I renamed a ViewController name using Refactor. The view controller name occurrences were changed but the real file not.
I tried to do what #ajji said but it didn't work. So I changed the name of the real file. After that all worked like a charm
If your file(s) - that couldn't find - icon color is pale. And you right click on it and "Show in Finder" does not open Finder. It means your file name is not same as what you see in the Navigator.
to Solve it, go to where your file exist, and change its name to be same as what you see in the Navigator.
I also faced same issue while building my xcode project - "Build input file cannot be found:"
Cause: I renamed my entire project but not the build setting.
Solution: In my project's build setting--> Packaging, I updated the path of the info.plist file. Now working fine.
If all else fails:
In Xcode. Remove references of files in question from your project.
Open your project.pbxproj file as a file in Xcode. This is in .xcodeproj
Delete all lines containing the name of said files. Save.
Back in Xcode. Re-add files to your project in Xcode.
In my case the file wasn't at the right path, Xcode was expecting to find the input file at a path like /Users/Malloc/Projects/MyProject/Info.plist while in reality the file was located at a different path like /Users/Malloc/Projects/MyProject/Subfolder/Info.plist.
A quick fix to this is to simply right click on the file then select Show in Finder, then drag the file to the correct path Xcode is expecting.
I got this error when i renamed a ViewController name using "Refactor". The view controller name occurrences were changed but an old reference was somewhere still existing.
Deleting derived data & Clean build folder worked for me.
Here's how to delete Derived data:
File>Workspace settings> Click arrow & remove all folders inside Derived Data.
In my case, it was due to localization.
Here's how to fix it.
How to localise a string inside the iOS info.plist file?
Update for Projects w/ Swift Packages
How did the errors happen?
I ran into this issue when I had imported Swift Packages into my project but later cleaned DerivedData to fix an unrelated app caching issue. My existing project was not a local Swift Package but an iOS app project.
Note that we can still encounter the same issue in local Swift Package projects.
What is the reason for the errors?
Swift Packages are checked out into DerivedData and are not referenced from the ModuleCache.noindex subfolder. Thus, cleaning the app's folder in DerivedData or DerivedData itself breaks dependency resolution within Xcode for Swift Packages.
This is a misleading build error since there may be nothing wrong with the app code you've written or your dependency resolution graph. The only thing required is to refresh the dependencies.
How can I resolve the build errors?
Xcode now has nice options within the IDE itself to resolve Swift Packages. These options trigger a new checkout into DerivedData:
We can use three options, as shown in the image above depending on our use case:
Reset Package Caches: Trigger a re-install of your existing Package dependencies w/ same versions.
Resolve Package Versions: Use this option for updating Package checkouts when fixing Package Versions for cross-compatibility (in Project Settings).
Update to Latest Package Versions: Use this to update all Swift Package dependencies to the latest versions. This option may be a local breaking change if the API changes.
NOTE: Apple's documentation recommends to use Xcode for dependency resolution when working with Xcode projects excluding CLTs.
Other solutions
We can also fix the error by restarting Xcode, but I find this step breaks my workflow and is tedious.
If we are running from the command line (local Swift Package executable), we can stick with a swift build variant without jumping to Xcode at all (Source). swift build doesn't work as easily out of the box in other projects, however.
Use xcodebuild:
xcodebuild -resolvePackageDependencies
I prefer staying in Xcode for simplicity but YMMV.
Goto Project Navigator.
Click on project.
Click on Targets.
Goto Build Settings.
Search Prefix.pch.
Change the location of this file (input the updated location).
This will resolve the issue as mine.
Had the same problem with swift files. Select files that are not recognised and Delete with Remove Reference option. Right click in the folder and Add files again.
In some cases, if you Refactor your existing ViewController files or any other files using right-click -> Refactor option within the Xcode workspace then on compiling this error will come since the File name is not changed in original place but reference is updated, so in that you need to also manually change the old file to new name.
When I checked out the code first time from the Git I faced the same issue for few pod file. Updating the pod file solved my issue.
Open the project folder in the terminal window
Run 'pod update'
Clean the XCode and run.
I just had to open the project in finder and drag/drop the appropriate files in the project folder
Build input file cannot be found
How to fix this issue?
My Approach:
1.From Project Navigator ->Files ->Add Files to Lowes ->In Finder View, check to which folder this lost referenced file is moved
to and check with your team members if anyone moved it for a reason.If it occurred by mistake
then follow below steps
2.From Project navigator, directly tap on the file which is causing issue.This is the same file that XCode shows as not found in
error .So clearly this file has lost reference and we need to
restore it back
3.The Swift bird folder icon appears in light red color which is an indication of lost reference
4.Right click on it and Delete it
5.Next from Project navigator -> Files ->Add Files to Lowes -> Finder View go to the folder where this referenced file is moved to
and tap on ADD button in popup window
6.Now if you look at the Project Navigator this file swift bird icon appears in bright red , but you will also find an extra file
with the same name at the top of the Project Navigator
7.Make sure you have this file in the right folder if not move it to right folder
8.Now right click to delete the very top redundant file, here do not select " Move to Trash" option.Just select "Remove References" option
This fixed my issue.
Adjust the file path according to that provided in the Xcode Error
My issue was a missing SettingsController file.
I copied a file from projectA to projectB but forgot to tick Copy items if needed. Unbeknownst to me a couple of weeks later when I deleted projectA the SettingsController file in projectB got deleted along with it. Afterwards in projectB the error Build input file cannot be found ... path/Folder/toSomeFile was shown.
To fix it I closed Xcode, went to the main folder that it was in, opened the folder and right clicked on the blue Xcode icon with the extension .xcodeproj, then I choose Show Package Contents
From there I double clicked on the project.pbxproj icon
Once the project.pbxproj file was opened I pressed command+f and in the search field I entered the path part of the error path/Folder/toSomeFile
It took me to 1-2 lines of code that looked like this
Once I deleted those 1-2 lines, when I went back to the projectB and opened it the error was gone.
Just for a little more clarity the exact path of the error was whogotgame_42/whogotgame/Controllers/SettingsController.swift. So that is what I exactly entered in the project.pbxproj search field to get to those 1-2 lines that you see in the picture.
I got this error when I put the Info.plist file inside a folder. Then when I extracted the file to public view, the error went away.
For some reason Xcode has stopped copying files to an app when I try running it.
In the past, I've dragged in a file, kept the "Copy items into destination group's folder (if needed)" option ticked, and all has been well.
Recently, however, I've had to go into the Targets / Build Phases / Copy Bundle Resources and manually add each file for it to be added to the app.
Is there a solution?
In the same view where you check "Copy items to destination group's folder" you have to check the targets you want to have access to the files!
If something like this happens, perform the following.
Close the project, not Xcode.
Open Organizer. Go to Projects ->
Delete the derived data for the required project.
Quit Xcode.
Go to the Project folder in the Finder. Open the package of your ---.xcodeproj
file. Other than the project settings file, delete all the files.
Now open Xcode and your project. First it will do some indexing of your
project. Then build and run.
Now it will add all the files.
I have an iphone project that is a "base" project. I want to copy this project, rename it and change a couple of files so as to create the final version of each application I want. How can I copy and rename a project in xcode 4.3+ without having any issues (like lost targets or so) ?
Click on your Project,
enter name of your project and prees enter,
it will ask,
Rename Project Content Items ?
say Rename then it will ask you for snapshot, click on Enable
and then press OK
Done !
You could also just create a new project and import only the header and code files you need.
I'm trying to 'import' my existing C++ codebase into my XCode iOS project.
Problem is, xCode won't compile (and therefore not link) my code.
This is what I've done so far:
File > Add files to "Project". I don't tick 'Copy files' since it's a shared codebase for multiple platforms and multiple copies of source code is not an option.
I've added appropriate path to the "Header Search Path" project settings. Including header files works, I can #include "stuff.h" from my Objective-C++ (.mm) file.
However, I can't find any way of actually telling XCode to compile the .cpp files?
A few points:
I'm not looking for a way to pre compile it into a library and linking that way
The project is a standard iOS Objective-C project. The C++ code is called from it (that's not a problem)
Update
I've added the codebase directory to the target's "Compile Sources". I actually have to click "Add other..." in the dialog that pops up, since I can't select the directory reference to my codebase.
When I add it, XCode asks me if I want to "Create external build system project". I leave it ticked and the two fields with the default values "/usr/bin/make" and "$(ACTION)". However, my codebase doesn't get compiled during the build. Do I have to write my own Makefile ?
If I don't select "Create external build system project" then a directory reference is created under the target, but not compiled during the build and a warning is emitted:
warning: no rule to process file '$(PROJECT_DIR)/../codebase'
of type folder for architecture i386
Even if you don't check Copy Files you have to check Add to Targets when adding the files to the project.
If you forgot to do that, you can select the target, go to the Build Phases tab and add the files to Compile Sources.
If you go to your Targets -> Build Phases -> Compile Sources -> "+" -> "Add Others" -> (select your external source folder) -> Select: Create Group for any added folders -> Unchecked: Copy items into destination.
Now your folder will be in XCode, mimic the structure. If you add source files to that folder in XCode the source files will be added to your external source directory just fine. So the ease of using multiple IDEs and having to manage source linkage is solved.
The catch. You still have to manually add files into the "Compile Sources" area. This is rather simple. Just click and drag your source files from the group directory in XCode right into the Compile Sources window. So there is an extra step when you add a source file now. Forgetting to add them to the Compile Sources window will yield unresolved symbols compile errors.
When I create a new project in Xcode 4 it does not create the resources folder like Xcode 3 used to do. Is there a setting in Xcode 4 to make this work?
As badcat indicates in his comments, the Resources folder was merely a group within the project template. To create your own Resources group, either right-click on the project explorer view and choose New Group, or go to the menu option File | New | New Group.
If you want to make sure that items which should be resources are copied into the correct location in your application bundle, you can click on the name of your project in the project explorer on the left of the screen and go to the Build Phases tab. You can expand the Copy Bundle Resources build phase (or whatever it's called in your project) and see the files that will be copied over. If something is missing, you can drag it into that list from the project explorer.
Not sure what you mean by "Resources" folder, but maybe this answer helps you with that:
Where is build output going?
Check out this question if you don't just want the group but also the physical folder on your filesystem: How do I get the resources folder back in Xcode 4?
